Xfsdump/Xfsrestore Troubleshooting Questions ============================================ SGI Support (relevant for IRIX customers only) ---------------------------------------------- * What is the customer support case number? * Is there an associated engineering bug number? * Do you have any existing contacts within SGI? General ------- * Have you run xfsdump or xfsrestore before? * Is this a new problem? And if so, what has changed since xfsdump or xfsrestore last worked correctly? Operating System (OS) --------------------- * What versions of the OS are you using now and when the dump was made ? (IRIX: uname -Ra or Linux: uname -a, cat /etc/issue) * What patches were installed for the OS ? * If Linux, what version of the xfsdump package are you using? (rpm -q xfsdump) * Is there anything in the /var/adm/SYSLOG file for the period that xfsdump or xfsrestore was run? File System (FS) ---------------- * How big is the filesystem being dumped ? (df -kl) * Does the filesystem have quotas enabled ? (mount) * Is the filesystem managed with DMF ? * Does the file system use Security attributes such as ACLs ? * Are extended attributes used in the filesystem ? * Is the filesystem controlled by CXFS, or the host part of a cluster? Tape System ----------- * Is TMF or Openvault used to manage the tapes ? If so, which versions? * What kind of tape drive is used ? * On IRIX, what kind of tape driver is used - tpsc or ts ? (eg. attr -g _drivername /dev/rmt/tps4d6) * Is the drive used in variable or fixed block mode ? (IRIX: look at the path for the tape specification) (Linux: mt -f /dev/st0 status; and report the blocksize) * How many tapes were used for the dump ? Dump/restore commands --------------------- * What was the xfsdump/xfsrestore command lines used ? * What was the output from the commands ? * If the FS is not too large, what is the output with the -v5 option ? * How big was the dump ? * What drive strategy was used in the commands? (xfsdump -v3 ... |grep "instantiat") (xfsrestore -v3 ... |grep "instantiat") If you have the -v5 output, then just grep for "instantiat". * If dumping/restoring to/from a remote host, what is the OS version of that host? * If xfsdump/xfsrestore seem to take a really long time, use the -p option to get progress output. * What is the output of 'xfsdump -I' ?

Dumps created with version 3.1.2 where extended attributes are in use failed to restore with v3.1.0 due to file header checksum errors. Thanks to Fugazzi for reporting. - Refactored release scripts to conform to using git archive. - Changed the build process so that 'make deb' uses the same process of creating a source tree as the release script. xfsdump-3.1.2 (13 December 2012) - Update release script to create a source tarball. xfsdump-3.1.1 (31 October 2012) - Save and restore 32 bit project ids correctly. - German translation, thanks to Chris Leick. - A few fixups to the German translation, thanks to Stefan Ring. - An initial Polish translation, thanks to Jakub Bogusz. - Various build system cleanups, thanks to Mike Frysinger, and Jan Engelhardt. xfsdump-3.1.0 (22 March 2012) - Fix metadata restore on split files. - Add a -D option to skip a recursive scan of the filesystem when dumping. - Fix a 1 byte overflow with empty lists, thanks to Mike Frysinger. - Enable multi-stream support on Linux using pthreads. - Fix handling of Ctrl-D in prompts. - Obsolete SGI_XFSDUMP_SKIP_FILE extended attribute for excluding files from dump. - Fix restoration of extended attributes on the root directory. - Use the full 32-bit inode generation number instead of 12-bit generation number. Bump the dump format version to 3. - Do not create parent directories for orphaned files during list-only (-t option) restore. xfsdump-3.0.6 (14 October 2011) - Unconditionally add checksums to various dump headers in xfsdump. - Verify dump header checksums if present in xfsrestore. - Convert to using the POSIX signal API. - Remove restriction of 8 options in dialogs. - Various refactoring and internal cleanups to xfsdump and xfsrestore. - Build system fixes, thanks to Ted Ts'o. xfsdump-3.0.5 (30 March 2011) - Release tags will now be digitally signed - Quota files will now be dumped, regardless of the maxsize setting - The new "-s sessid" flag allows inventory sessions to be pruned by their session ID. - Fixed a bug in handling long dump filenames, and dropped (undocumented) support for encoding certain parameters within the dump filename - NODECHK is now off by default, meaning xfsrestore will now support 16 times more directory entries (4 billion) - nrh_t is now 64 bits wide, allowing xfsrestore to support dumps with up to 4 billion directory entries - nix_t is no longer useful, and has been eliminated - Memory use in xfsrestore is better managed now. Segments of nodes are now power-of-2 sized, and allocated nodes are no longer needlessly zeroed and linked into the free list. - Pathname resolution in xfsrestore has a number of performance improvements - Better checking has been implemented for compatibility when resuming a cumulative restore - Build system output has been cleaned up considerably - Dead "namreg" code has been removed - Build dependencies are now determined automatically - Other miscellaneous build system improvements, as well bug fixes thanks to Mike Frysinger and Arkadiusz MiÅ›kiewicz. xfsdump-3.0.4 (13 January 2010) - Improve xfsinvutil man page and argument processing. - Fix timestamp handling on 64-bit architectures in xfsinvutil. - Various build system improvements. xfsdump-3.0.2 (9 May 2009) - Update the Debian packaging and resolve xfsprogs dependencies. xfsdump-3.0.1 (5 May 2009) - Update the Makepkgs script to generate proper source tarballs. - Small specfile improvements, thanks to Jan Engelhardt. - Fix parallel builds, thanks to Mike Frysinger. - Various autoconf/libtool fixes, thanks to Andreas Gruenbacher. xfsdump-3.0.0 (4 February 2009) - Bump major package version number to signify changed dependencies and moved binaries (xfs_fsr and estimate have moved into xfsprogs). - xfsdump should no longer make use of internal XFS headers and libraries, in particular no use of libxfs is permitted in this package anymore (such detailed on-disk format knowledge is the realm of xfsprogs). - Fix xfsdump/xfsrestore to work on systems with 64k page size. xfsdump-2.2.49 (17 Feb 2008) - Fix up error handling in _rmt_open in librmt. Warnings reported by Michal Marek xfsdump-2.2.48 (07 Feb 2008) - Prune dump sessions with 0 media files even when using -m. xfsdump-2.2.47 (01 Feb 2008) - Correctly detect whether a tape device is in variable or fixed block mode when using the TS tape driver. xfsdump-2.2.46 (24 Aug 2007) - Specify mode on all open(2) calls that use O_CREAT. xfsdump-2.2.45 (24 May 2007) - Change fsr's temp directory mode to 0700 to deny full access. - Update fsr's usage text. xfsdump-2.2.44 (01 February 2007) - Fix use of getopt's optopt variable. Thanks to Kouta Ooizumi. - Initialize xfsdump's logging facility earlier. Thanks to Kouta Ooizumi. - Log a message for each quota file restored, not just the first. - When using -z, check a file's size against the max dump file size just before dumping the file, rather than only during the initial scan, to account for changes during the dump. - A sync needs to be issued before the first inode scan to avoid potentially skipping modified files in an incremental dump. xfsdump-2.2.43 (02 October 2006) - Change the inode scans to seek to the next inode of interest, rather than always doing a full scan. Useful for dumps that contain only a subset of the inodes in a filesystem (incrementals, subtree dumps, etc.). - Produce a more accurate dump size estimate when it is worthwhile to do so (when using multiple dump streams or when skipping files based on size). xfsdump-2.2.42 (08 August 2006) - Rework code to remove the DMAPI build and run-time dependency. xfsdump-2.2.41 (14 July 2006) - Fix issues with makedepend on libtool libraries. - Fix issues with symbolic link handling in Makefiles. xfsdump-2.2.40 (05 July 2006) - Update translation Makefile to work better with the Ubuntu translation system. Thanks to feedback from Martin Pitt. - Fix annoying "ignores datarootdir" warning from configure. - Fix issues with makedepend build infrastructure. xfsdump-2.2.39 (21 June 2006) - Fix for parallel compiles, thanks to Robin H. Johnson. xfsdump-2.2.38 (06 June 2006) - Performance improvements for dumping subtrees. xfsdump-2.2.37 (24 May 2006) - Fix xfs_fsr memory and file descriptor leaks. - Fix xfs_fsr handling some of the extended inode flags and fields (like project IDs, extsize, realtime, etc). - Fix Debian packaging for libc-dev build dependency. - Fix up auto lib64 install detection for x86_64 platforms. - Use -O2 optimisation by default now like everywhere else. - Default to using a single media file for each strategy. Multiple media files can be enabled on tape strategies by using the -d option. - Fix a bug in restoring multiple links to files with the immutable bit set. - Fix a regression that caused xfsrestore to fail when restoring files that were changing during the dump. - Remove some overhead in restoring files that were dumped in multiple extent groups (> 16 MiB). - Add simple interface to HSM-specific code in xfsrestore, similar to that already in xfsdump. - Fix fsr mishandling directories given as arguments. - Fix build dependency on recent xfsprogs header files. xfsdump-2.2.36 (15 February 2006) - Debian packaging updates (debmake out, debhelper in). - Minor man page fixups with respect to hyphenation. xfsdump-2.2.35 (07 February 2006) - Merge some minor changes in from IRIX. xfsdump-2.2.34 (31 January 2006) - Updated the spec file to correctly set package user/group. - Optimizations to increase the performance of xfsdump and xfsrestore, especially on filesystems with millions of inodes. Many small changes were made to minimize the number of system calls required per inode. - Significant changes to xfsdump: o Cache the gen number of each inode during the initial inode scan so that a bulkstat single does not need to be done for each inode when dumping directories. o No longer retrieve the DMF attribute when estimating the dump size of a file. Use information from the bulkstat instead. o Retrieve DMF attribute by handle instead of doing open/attr_getf/close. o In determining where to split multi-stream dumps, take into consideration the number of files and not just the file size. This allows filesystems with large amounts of inodes but relatively little data (DMF filesystem) to be split correctly. - Significant changes to xfsrestore: o Buffer writes to the namreg file to eliminate 2 very small write system calls per directory entry. o Buffer writes to dirattr file to eliminate a small write system call per directory. o Speedup the check to see if a particular window of the tree file is mapped. This allows xfsrestore to use more, smaller windows which is beneficial if we can't fit them all in memory and have to start unmapping them. This also makes the -w option obsolete so that option now has no effect. o Change the hash function to give a better distribution among the hash buckets. o Do not make an unnecessary unlink call if the file being restored does not already exist. xfsdump-2.2.33 (16 December 2005) - Add option to allow dump time to be overridden. Useful if doing incremental dumps of snapshots. Thanks to David Brown. xfsdump-2.2.32 (29 November 2005) - Dump and restore project ids and project quotas. - Remove xfsdq(8) and xfsrq(8); use xfs_quota(8) to dump and restore quotas now. - Fix the setting of extended inode flags during restore. Some flags must be set before writing file data, and others must be set after writing file data and extended attributes. xfsdump-2.2.31 (10 November 2005) - Sync up build system (m4 macros, etc) with other projects - Update SGI copyright/licence notices xfsdump-2.2.30 (27 July 2005) - Fix some problems in the xfsrq(8) script, thanks to Kim Hansen. xfsdump-2.2.29 (23 June 2005) - Change xfsrestore to retry a write that fails with ENOSPC after issuing a fdatasync call. If it still fails, issue a sync call and retry once more. xfsdump-2.2.28 (03 June 2005) - removal of unnecessary stat64_to_xfsbstat function xfsdump-2.2.27 (08 March 2005) - Fix compilation with gcc4, from Andreas Jochens. xfsdump-2.2.26 (09 February 2005) - Fix xfsrestore so that it can restore to non-XFS filesystems again. xfsdump-2.2.25 (13 October 2004) - Bump the version to deal with the mixup in 2.2.23-lbs (that fix was missing from the 2.2.23/2.2.24 versions). xfsdump-2.2.23-lbs (04 October 2004) - Fix a problem dumping DMF filesystems when files change from dual-state to offline during the dump. xfsdump-2.2.24 (29 Sep 2004) - Update m4 macros, incorporating some portability changes. xfsdump-2.2.23 (21 Jul 2004) - Fix up xfs_fsr and xfsdump to prevent possible crashes on 64 bit machines such as Alphas, when using a 64 bit count passed to bulkstat when only 32 bits of it have been set by bulkstat. Suggestion came from Jan-Jaap van der Heijden. See http://oss.sgi.com/bugzilla/show_bug.cgi?id=346 for details. xfsdump-2.2.22 (19 Jul 2004) - Add support for new DMF attribute format. - Fix bug in HSM code where a DMF attribute could be generated for both the root and secure extended attribute namespaces. xfsdump-2.2.21 (15 Apr 2004) - Always allocate a filesystem handle on restore instead of doing so only when restoring DMAPI events, as the filesystem handle is also needed if restoring extended attrs. - Remove path_to_fshandle calls in tree.c. These existed to ensure that we always had a fshandle before calling open_by_handle. These calls are extraneous since we now allocate a fshandle during context_init. - Change open_by_fshandle calls to open_by_handle since we are passing a file handle, not a fshandle. xfsdump-2.2.20 (31 March 2004) - fix up "xfs_invutil -i" which was getting segmentation faults on presumably long session labels. See http://oss.sgi.com/bugzilla/show_bug.cgi?id=320. Become paranoid and convert all sprintf's to snprintf's. xfsdump-2.2.19 (23 March 2004) - rearrange fsr algorithm to not copy data unless extent count has been improved. Suggested by Chris Wedgwood and Utz Lehmann xfsdump-2.2.18 (25 February 2004) - add support for the security extended attributes namespace xfsdump-2.2.17 (13 February 2004) - modify calls to libhandle subroutines to account for changes to the libhandle library. xfsdump-2.2.16 (05 December 2003) - fix xfsrestore to restore new XFS inode flags: immutable, append, sync, noatime and nodump. The inode flags have also been added to the _mk_fillconfig_ea() routine in common.dump, called by QA test 063 to test inode flags and xattrs. - fix xfsdump to honor the new nodump xflag, "XFS_XFLAG_NODUMP", (in conjunction with -e). The original method to skip files, -e plus extended attribute "SGI_XFSDUMP_SKIP_FILE", is still supported. Admins may choose which method to use. The xfsdump man page has been updated to document these changes. - update man pages with a more detailed description of the inventory media file that gets written to the end of each dump. - remove 'miniroot' reference from xfsdump man page. xfsdump-2.2.15 (18 December 2003) - a mod was added in 2.2.13 to fix the way xfsdump handles multiple dump sessions to a single tape. The mod fixed problems that the TS tape driver was hitting but actually broke multiple backup functionality using the ST tape driver. Both problems (ST and TS) are fixed in 2.2.15. xfsdump-2.2.14 (18 October 2003) - update Debian packaging to require latest dmapi packages. xfsdump-2.2.13 (21 July 2003) - fix ST/TS tape driver compatibility issues in drive_scsitape. - fix multiple backups to a single tape (TS AND ST). xfsdump-2.2.12 (29 May 2003) - fix up an invutil Makefile botch which was effectively disabling the optional ncurses support (interactive mode). xfsdump-2.2.11 (26 April 2003) - rework configure.in to make use of shared macros. - fix up #include lines to allow compilation of sources with installed headers rather than local headers. - update Debian packaging. - fix up a botch in the RPM packaging from 2.2.8. xfsdump-2.2.10 (14 April 2003) - fix configure tests that used AC_PATH_PROG incorrectly. - switch from using mktemp to using mkstemp for xfs_copy log. - use a FHS compliant name for the xfs_copy log file. xfsdump-2.2.9 (27 March 2003) - add -f option to xfsdq(8) to specify an output file instead of using the standard output stream. This file is created by xfsdq and xfsdq will fail to run if it exists already. The file is also created with a more appropriate mode than whatever the umask happened to be when xfsdump(8) was run. xfsdump-2.2.8 (27 March 2003) - cleanups to the build process, in particular the automatic rpm package generation Makefile and spec file template. - Makepkgs script can now propagate failures back from make. xfsdump-2.2.7 (13 March 2003) - add initial support for TS tape driver. (19 February 2003) - fix xfsdump -I option to set correct fsid. xfsdump-2.2.6 (19 December 2002) - add initial internationalisation support. xfsdump-2.2.5 (19 December 2002) - fix build fallout from macro changes in XFS headers. - add a configure check so that we don't attempt to build against old versions of the headers. xfsdump-2.2.4 (08 November 2002) - configure now looks for, and xfsinvutil uses, the ncurses header and library rather than the curses version - this resolves an issue in those distributions that don't make the compatibility library available. xfsdump-2.2.3 (31 October 2002) - minor update to Debian packaging dependencies. - inventory related bugfix. xfsdump-2.2.2 (03 October 2002) - Remove fork/setuid from fsr. Just chown temp. file to owner. This gets fsr working again with the restricted RESVSP ioctl. Chris Wedgwood xfsdump-2.2.1 (24 September 2002) - minor troff-version-specific fixups for xfsrestore(8). xfsdump-2.2.0 (03 September 2002) - force use of version 1 XFS geometry ioctl everywhere in xfsdump package, so that these tools can still work on older kernels (they don't need the additional information in the new ioctl). - added new config.h.in and configure changes to implement this. - do some additional cleanup after autoconf has run. xfsdump-2.1.5 (14 August 2002) - minor build fix when using relatively old versions of glibc which don't provide the SYS_getdents64 symbol. xfsdump-2.1.4 (01 August 2002) - xfsinvutil -m option added (merge from IRIX). - add missing GPL/copyright headers to several xfsinvutil files. - correct several uses of uuid_compare in xfsinvutil. xfsdump-2.1.3 (30 July 2002) - small xfsinvutil fixups to preserve compatibility with old -n option. - fixed all new xfsinvutil warnings on 64bit platforms xfsdump-2.1.2 (29 July 2002) - xfsinvutil interactive mode - merge of a dump/restore fix from IRIX - test if a child exited with error and if a child did, set the exit_code to EXIT_ERROR. xfsdump-2.1.1 (04 July 2002) - build infrastructure updates so that configure options can be used to specify paths rather than semi-hard-coded path names controlled by the ROOT/ROOT_PREFIX environment variables; eg. now allows /lib64 and /lib32 xfsdump-2.1.0 (14 June 2002) - new fsinfo system call used, mostly changing version to differentiate this. xfsdump-2.0.4 (14 June 2002) - fix xfsrestore/xfsdump version output to report both their version and the respective dump format version. They will report their version from cmd/xfsdump/VERSION. - changed the messages printed out for the xfsrestore interactive mode to emphasize the restore is interactive. xfsdump-2.0.3 (08 May 2002) - fix xfsdump so that it does not cause segmentation fault when media specific object id (OPT_MOBJID) is specified with -I option. - fix similar code for filesystem id (OPT_FSID) option. xfsdump-2.0.2 (08 May 2002) - in xfsdump, check for ERANGE as well as E2BIG for testing of the existence of the SGI_XFSDUMP_SKIP_FILE extended attribute. This only affects dumping using the -e option. This was motivated by an XFS kernel change from returning E2BIG into returning ERANGE. - fix "xfsdump -v silent" to really be silent xfsdump-2.0.1 (13 April 2002) - minor build system updates xfsdump-2.0.0 (07 February 2002) - rework all code dealing with extended attributes to use the new system calls (requires attr-2.0.0 or greater) - also, the attrctl-by-handle ioctl is history, replaced by libhandle routines - more like what we have in IRIX (requires xfsprogs-2.0.0 or greater) - effectively no-op change (cleanup) - switch over to using XFS_IOC_FSGEOMETRY instead of XFS_IOC_GETFSUUID ioctl, so we can deprecate that "special" UUID ioctl in the kernel. - add -q description to xfsdump/xfsrestore man pages and usage text. - change failed bulkstat WARNING to a TRACE message to that it doesn't bother people. - avoid a possible assertion failure for cumulative restores with -B option. xfsdump-1.1.14 (16 January 2002) - fix xfsrestore so that cumulative restores (with -r) will successfully delete removed directories whose files have also been removed. Previously, the files weren't removed until later, which meant that early directory removal failed. SGI bug#844219. xfsdump-1.1.13 (11 January 2002) - fix xfsdump so that if an inode# is reused in the time between building the inode map and pruning the inode map (in phase 3 when some dirs are marked as not changed), that it no longer aborts with an assertion failure. SGI bug#846374. xfsdump-1.1.12 (14 December 2001) - add new -B option to xfsrestore to correctly assign ownership and permissions of the dump root directory to the destination directory xfsdump-1.1.11 (13 December 2001) - port back IRIX changes primarily to xfsrestore for improving performance when one has over a million files - some extra mlogs (messages) for dump estimates, dir tree diagnostics, type of dump format being used - various fixes for restore with multiple threads and extended attributes (note: multiple threads not implemented on Linux yet) xfsdump-1.1.10 (10 December 2001) - fix xfsdump to endian convert all of the record header fields properly just prior to writing the header out (in particular first_mark_offset). This caused do_next_mark() assertion failures at some sites. xfsdump-1.1.9 (28 November 2001) - fix xfsrestore so that it doesn't delete hardlinks on alternate cumulative restores xfsdump-1.1.8 (14 November 2001) - allow xfsdump to exclude files based on whether they have a certain extended attribute set - don't include /var/lib/xfsdump in the dump xfsdump-1.1.7 (18 October 2001) - xfsrestore -t will no longer fail if the current working directory is not xfs - xfsrestore will no longer issue (harmless) warnings related to space pre-allocation if it is writing to a non-xfs filesystem xfsdump-1.1.6 (03 October 2001) - get rid of useless stkchk abstraction (will no longer get stack info messages with -v proc=debug) - FHS compliance for inventory directory (/var/lib/xfsdump), and existing installations will continue to work as is. - A future xfsdump release will have an updated xfsinvutil to allow the old directory to be migrated to the new manually, without corrupting the inventory (its one or the other only though, not both, and this is enforced by the tools) xfsdump-1.1.5 (28 September 2001) - changes for ia64 (e.g. time32_t, getdents, librmt mtget changes) - fix dump/restore to be able to use drive_scsitape with devfs xfsdump-1.1.4 (18 September 2001) - fix librmt to allow a remote path without "/dev" in its name - this allows xfsdump/xfsrestore to remote file - fix librmt for remote uname to use env variable RSH - add some diagnostics to xfsdump xfsdump-1.1.3 (27 July 2001) - fixes for (hopefully) the last few nits in libtool usage xfsdump-1.1.2 (24 July 2001) - merge in phase 3 changes from review and further testing - merge in code to specify maximum file size for xfsdump (-z) - merge in code to specify media file size for xfsdump (-d) - merge in code to request single media file for xfsdump (-S) - merge a couple of minor bug fixes from IRIX xfsdump-1.1.1 (23 July 2001) - look for libtool archives in /usr/lib, not /lib xfsdump-1.1.0 (18 July 2001) - rework package to use libtool - merge fsr bug fixes from IRIX - merge xfsdump phase 3 performance fixup from IRIX - enable use of (shared) libhandle.so and libattr.so - re-enable use of libdm.so for DMAPI support - remove some more unused "common" files - man page updates for xfsdump and xfsrestore - moved certain binaries from /usr/sbin into /sbin to be available for recovery when only root is mounted xfsdump-1.0.12 (13 July 2001) - Fix mistake introduced in 1.0.10 whereby xfsdump/xfsrestore to remote tape drives will cause rmt debug messages to be written to the remote machine in: /server.XXX (where XXX = pid). These files will no longer be created via xfsdump/xfsrestore. The fix is in librmt - it should have only written out warning messages and not debug messages. If the debug environment variable is turned on for librmt then the debug file will go to /tmp/librmt_debug.XXX. xfsdump-1.0.11 (12 July 2001) - correctly restore block and character device major numbers xfsdump-1.0.10 (05 July 2001) - produce librmt warning messages from xfsdump/xfsrestore without needing to set an environment variable xfsdump-1.0.9 (15 May 2001) - correctly [xfs]restore the suid and guid mode bits xfsdump-1.0.8 (12 May 2001) - added build dependency for Debian on latest devel package xfsdump-1.0.7 (07 May 2001) - fix warnings, remove last -Wall filter - configure script default man path now /usr/share/man - support realtime files in dump/restore - cleanup arch-specific code, esp. the byteswab routines - as a result, move to -O1 as default for extern inlines - fix bug dumping to remote tape device with given user xfsdump-1.0.6 (01 May 2001) - remove spurious warnings when dumping quota information xfsdump-1.0.5 (09 April 2001) - fix use of an uninitialised variable in dump - fix a number of compiler warnings xfsdump-1.0.4 (03 April 2001) - added xfsdump support for dumping quota information xfsdump-1.0.3 (28 March 2001) - minor rpm spec file changes - added xfsdq and xfsrq for dumping quota information xfsdump-1.0.2 (10 January 2001) - support extended attributes in xfsdump and xfsrestore xfsdump-1.0.1 (30 January 2001) - minor rpm and deb packaging work xfsdump-1.0.0 (15 January 2001) - dump, restore, fsr and co. abstracted from xfs-cmds package - completed Debian packaging - late beta code

Linux Caveats

These notes are written for xfsdump and xfsrestore in IRIX. Therefore, it refers to some features that aren't supported in Linux. For example, the references to multiple streams/threads/drives do not pertain to xfsdump/xfsrestore in Linux. Also, the DMF support in xfsdump is not yet useful for Linux.

What's in a dump

Xfsdump is used to dump out an XFS filesystem to a file, tape or stdout. The dump includes all the filesystem objects of:
  • directories (S_IFDIR)
  • regular files (S_IFREG)
  • sockets (S_IFSOCK)
  • symlinks (S_IFLNK)
  • character special files (S_IFCHR)
  • block special files (S_IFBLK)
  • named pipes (S_FIFO)
  • XENIX named pipes (S_IFNAM)
but not mount point types (S_IFMNT). It also does not dump files from /var/xfsdump which is where the xfsdump inventory is located. Other data which is stored:
  • file attributes (stored in stat data) of owner, group, permissions, and date stamps
  • any extended attributes associated with these file objects
  • extent information is stored allowing holes to be reconstructed on restoral
  • actual file data of the extents

Dump Format

The dump format is the layout of the data for storage in a dump. This is mostly done at an abstraction above the media dump format (tape or data file). The tape format, for example, will have extra header records. The tape format will be done in multiple media files, whereas the data file format will use 1 media file.

Media Files

Media files are probably used to provide a way of recovering more data in xfsrestore(1) should there be some media error. They provide a self-contained unit for restoration. If the dump media is a disk file (drive_simple.c) then I believe that only one media-file is used. Whereas on tape media, multiple media files are used depending upon the size of the media file. The size of the media file is set depending on the drive type (in IRIX): QIC: 50Mb; DAT: 512Mb; Exabyte: 2Gb; DLT: 4Gb; others: 256Mb. This value (media file size) is now able to be changed by the "-d" option. . Also, on tape, the dump is finished by an inventory media file followed by a terminating null media file.

A global header is placed at the start of each media file. 

global_hdr_t (4K bytes)
magic# = "xFSdump0"
version#
checksum
time of dump
ip address
dump id
hostname
dump label
pad to 1K bytes
drive_hdr_t (3K bytes)
    drive count
    drive index
    strategy id = on-file, on-tape, on-rmt-tape
    pad to 512 bytes

    specific (512 bytes)
        tape:
	    rec_hdr
	    magic# - tape magic = 0x13579bdf02468acell
	    version#
	    block size
	    record size
	    drive capabilities
	    record's byte offset in media file
	    byte offset of rirst mark set
	    size (bytes) of record containing user data
	    checksum (if -C used)
	    ischecksum (= 1 if -C used)
	    dump uuid
	    pad to 512 bytes

    upper: (2K bytes)
	media_hdr_t
	media-label
	previous media-label
	media-id
	previous media-id
	5 media indexes - (indices of object/file within stream/media-object)
	strategy id = on-file, on-tape, on-rmt-tape
	strategy specific data:
	  field to denote if media file is a terminator (old fmt)
	upper: (to 2K)

Note that the strategy id is checked on restore so that the dump strategy and the strategy used by restore are the same with the exception that drive_scsitape matches with drive_minrmt. This strategy check has caused problems with customers in the past. In particular, if one sends xfsdump's stdout to a tape (i.e. xfsdump -L test -M test - / >/dev/tape) then one can not restore this tape using xfsrestore by specifying the tape with the -f option. There was also a problem for a time where if one used a drive with the TS tape driver, xfsdump wouldn't recognise this driver and would select the drive_simple strategy.

Inode Map

Directories

Non-directory files


Regular files, as can be seen from above, have a list of extents followed by the file's extended attributes. If the file is large and/or the dump is to multiple streams, then the file can be dumped in multiple records or extent groups. (See Splitting a Regular File).

Format on Tape

At the beginning of each tape record is a header. However, for the first record of a media file, the record header is buried inside the global header at byte offset 1536 (1K + 512), as is shown in the global header diagram. Reproduced again: 
rec_hdr
magic# - tape magic = 0x13579bdf02468acell
version#
block-size
record-size
drive capabilities
record's byte offset in media file
byte offset of rirst mark set
size (bytes) of record containing user data
checksum (if -C used)
ischecksum (= 1 if -C used)
dump uuid
pad to 512 bytes

I can not see where the block-size ("tape_blksz") is ever used ! The record-size ("tape_recsz") is used as the byte count to do the actual write and read system calls.

There is another layer of s/ware for the actual data on the tape. Although, one may write out an inode-map or directory entries, one doesn't just give these record buffers straight to the write system call to write out. Instead, these data objects are written to buffers (akin to <stdio>). Another thread reads from these buffers (unless its running single-threaded) and writes them to tape. Specifically, inside a loop, one calls do_get_write_buf, copies over the data one wants stored and then calls do_write_buf, until the entire data buffer has been copied over.

Run Time Structure

This section reviews the run time structure and failure handling in dump/restore (see IRIX PV 784355). The diagram below gives a schematic of the runtime structure of a dump/restore session to multiple drives. 


1.           main process	main.c
	       /  |   \
	      /   |    \
2.	stream  stream  stream	dump/content.c restore/content.c
       manager  manager manager
	   |      |      |
3.	 drive  drive   drive	common/drive.[hc]
	object  object  object
	   |      |      |
4.	   O      O      O	ring buffers common/ring.[ch]
           |      |      |
5.	 slave  slave   slave	ring_create(... ring_slave_entry ...)
	thread  thread  thread
	   |      |      |
6.	 drive  drive   drive	physical drives
	device  device  device

Each stream is broken into two threads of control: a stream manager; and a drive manager. The drive manager provides an abstraction of the tape device that allows multiple classes of device to be handled (including normal files). The stream manager implements the actual dump or restore functionality. The main process and stream managers interact with the drive managers through a set of device ops (e.g.: do_write, do_set_mark, ... etc).

The process hierachy is shown above. main() first initialises the drive managers with calls to the drive_init functions. In addition to choosing and assigning drive strategies and ops for each drive object, the drive managers intialise a ring buffer and (for devices other than simple UNIX files) sproc off a slave thread that that handles IO to the tape device. This initialisation happens in the drive_manager code and is not directly visible from main().

main() takes direct responsibility for initialising the stream managers, calling the child management facility to perform the sprocs. Each child begins execution in childmain(), runs either content_stream_dump or content_stream_restore and exits with the return code from these functions.

Both the stream manager processes and the drive manager slaves set their signal disposition to ignore HUP, INT, QUIT, PIPE, ALRM, CLD (and for the stream manager TERM as well).

The drive manager slave processes are much simpler, and are initialised with a call to ring_create, and begin execution in ring_slave_func. The ring structure must also be initialised with two ops that are called by the spawned thread: a ring read op, and a write op. The stream manager communicates with the tape manager across this ring structure using Ring_put's and Ring_get's.

The slave thread sits in a loop processing messages that come across the ring buffer. It ignores signals and does not terminate until it receives a RING_OP_DIE message. It then exits 0.

The main process sleeps waiting for any of its children to die (ie. waiting for a SIGCLD). All children that it cares about (stream managers and ring buffer slaves) are registered through the child manager abstraction. When a child dies wait status and other info is stored with its entry in the child manager. main() ignores the deaths of children (and grandchildren) that are not registered through the child manager. The return status of these subprocesses is checked and in the case of an error is used to determine the overall exit code.

We do not expect slave threads to ever die unexpectedly: they ignore most signals and only exit when they receive a RING_OP_DIE at which point they drop out of the message processing loop and always signal success.

Thus the only child processes that can affect the return status of dump or restore are the stream managers, and these processes take their exit status from the values returned by content_stream_dump and content_stream_restore.

xfsdump

Control Flow of xfsdump

Below is a higher level summary of the control flow. Further details are given later.
  • initialize the drive strategy for a tape, file, minimal remote tape
  • create the global header

content_init (xfsdump version)

Do up to 5 phases, which create and prune the inode map, calculate an estimate of the file data size and using that create inode-ranges for multi-stream dumps if pertinent.

  • phase 1: create a subtree list based on the -s subtree spec.
  • phase 2: create the inode map
    The inode map stores the type of the inode: directory or non-directory, and a state value to say whether it has changed or not. The inode map is built by processing each inode (using bulkstat) and in order to work out if it should be marked as changed, by comparing its date stamp with the date of the base or interrupted dump. We also update the size for non-dir regular files (bs_blocks * bs_blksize)
  • phase 3: prune the unneeded subtrees due to the set of unchanged directories or the subtrees specified in -s (phase 1). This works by marking higher level directories as unchanged (MAP_DIR_NOCHNG) in the inode map.
  • phase 4: estimate non-dir (file) size if pruning was done since phase 2. It calculates this by processing each inode (using bulkstat) and looking up the inode map to see if it is a changed non-dir (file). If it is then it uses (bs_blocks * bs_blksize) as in phase 2.
  • phase 5: if we have multiple streams, then it splits up the dump to try to give each stream a set of inodes which has an equal amount of file data. See the section on "Splitting a dump over multiple streams" below.
  • if 1 stream, then we call content_stream_dump and if multi stream, then we create children sprocs which call content_stream_dump.

content_stream_dump

  • write global header
  • loop dumping media files
    • dump the changed/needed directories by processing all inodes from bulkstat
      • dump the filehdr based on the bulkstat structure
      • dump the directory entries (using getdents())
      • dump a null dirent terminator
      • dump extended attributes on directory if it has them
    • dump the changed/needed files by processing all inodes from bulkstat (check the multistream range to see if it should be dumped by this particular stream)
      • dump the filehdr
      • dump the extents (called extent groups - max at 16Mb)
        • align to page boundary by dumping EXTENTHDR_TYPE_ALIGN records
        • dump data as EXTENTHDR_TYPE_DATA records
      • dump a null terminator, EXTENTHDR_TYPE_LAST
    • if not EOM then write null file header
    • end the media file
    • update online inventory
  • if multiple-media dump (i.e. tape dump and not file dump) then
    • dump the session inventory to a media file
    • dump the terminator to a media file
The main function of xfsdump
* drive_init1 - initialize drive manager for each stream
  - go thru cmd options looking for -f device
  - each device requires a drive-manager and hence an sproc 
    (sproc = IRIX lightweight process)
  - if supposed to run single threaded then can only
    support one device

  - ?? each drive but drive-0 can complete file from other stream
  - allocate drive structures for each one -f d1,d2,d3
  - if "-" specified for std out then only one drive allowed

  - for each drive it tries to pick best strategy manager
    - there are 3 strategies 
      1) simple - for dump on file
      2) scsitape - for dump on tape
      3) minrmt - minimal protocol for remote tape (non-SGI)
    - for given drive it is scored by each strategy given
      the drive record which basically has device name,
      and args
    - set drive's strategy to the best one and
      set its strategy's mark separation and media file size
    - instantiate the strategy
      - set flags given the args
      - for drive_scsitape/ds_instantiate
	  - if single-threaded then allocate a buffer of
	    STAPE_MAX_RECSZ page aligned
	  - otherwise, create a ring buffer
      - note if remote tape (has ":" in name)
      - set capabilities of BSF, FSF, etc.

Splitting a Regular File

If a regular file is greater than 16Mb (maxextentcnt = drivep->d_recmarksep = recommended max. separation between marks), then it is broken up into multiple extent groups each with their own filehdr_t's. A regular file can also be split, if we are dumping to multiple streams and the file would span the stream boundary.

Splitting a dump over multiple streams (Phase 5)

If one is dumping to multiple streams, then xfsdump calculates an estimate of the dump size and divides by the number of streams to determine how much data we should allocate for a stream. The inodes are processed in order from bulkstat in the function cb_startpt. Thus we start allocating inodes to the first stream until we reach the allocated amount and then need to decide how to proceed on to the next stream. At this point we have 3 actions:
Hold
Include this file in the current stream.
Bump
Start a new stream beginning with this file.
Split
Split this file across 2 streams in different extent groups.

Persistent Inventory and State File

The persistent inventory is found inside the "state" file. The state file is an mmap'ed file called $dstdir/xfsrestorehousekeepingdir/state. The state file (struct pers from content.c) contains a header of:
  • command line arguments from 1st session,
  • partial registry data structure for use with multiple streams and extended attributes,
  • various session state such as dumpid, dump label, number of inodes restored so far, etc.

Followed by pages for the subtree selections and then the persistent inventory.
So the 3 main sections look like: 
"state" mmap file
---------------------
| State Header      |
| (number of pages  |
|  to hold pers_t)  |
| pers_t:           |

|   - etc...        |

|   - dumpid        |

Restore's directory entry tree

As can be seen in the directory dump format above, part of the dump consists of directories and their associated directory entries. The other part consists of the files which are just identified by their inode# which is sourced from bulkstat during the dump. When restoring a dump, the first step is reconstructing the tree of directory nodes. This tree can then be used to associate the file with it's directory and so restored to the correct location in the directory structure.

The tree is an mmap'ed file called $dstdir/xfsrestorehousekeepingdir/tree. Different sections of it will be mmap'ed separately. It is of the following format: 

--------------------
|  Tree Header     | <--- ptr to root of tree, hash size,...
|  (pgsz = 16K)    |
--------------------
|  Hash Table      | <--- inode# ==map==> tree node
--------------------
|  Node Header     | <--- describes allocation of nodes
|  (pgsz = 16K)    |
--------------------
|  Node Segment#1  | <--- typically 1 million tree nodes
--------------------
|  ...             |
|                  |
--------------------
|  Node Segment#N  |
--------------------

The tree header is described by restore/tree.c/treePersStorage, and it has such things as pointers to the root of the tree and the size of the hash table. 

        ino64_t p_rootino - ino of root
        nh_t p_rooth - handle of root node
        nh_t p_orphh - handle to orphanage node
        size64_t p_hashsz - size of hash array
        size_t p_hashmask - hash mask (private to hash abstraction)
        bool_t p_ownerpr - whether to restore directory owner/group attributes
        bool_t p_fullpr - whether restoring a full level 0 non-resumed dump
        bool_t p_ignoreorphpr - set if positive subtree or interactive
        bool_t p_restoredmpr - restore DMI event settings

The hash table maps the inode number to the tree node. It is a chained hash table with the "next" link stored in the tree node in the n_hashh field of struct node in restore/tree.c. The size of the hash table is based on the number of directories and non-directories (which will approximate the number of directory entries - won't include extra hard links). The size of the table is capped below at 1 page and capped above at virtual-memory-limit/4/8 (i.e. vmsz/32) or the range of 2^32 whichever is the smaller.

The node header is described by restore/node.c/node_hdr_t and it contains fields to help in the allocation of nodes. 

        size_t nh_nodesz -  internal node size
        ix_t nh_nodehkix -
        size_t nh_nodesperseg - num nodes per segment
        size_t nh_segsz - size in bytes of segment
        size_t nh_winmapmax - maximum number of windows
                              based on using up to vmsz/4
        size_t nh_nodealignsz - node alignment
        nix_t nh_freenix - pointer to singly linked freelist
        off64_t nh_firstsegoff - offset to 1st segment
        off64_t nh_virgsegreloff - (see diagram)
                 offset (relative to beginning of first segment) into
                 backing store of segment containing one or
                 more virgin nodes. relative to beginning of segmented
                 portion of backing store. bumped only when all of the
                 nodes in the segment have been placed on the free list.
                 when bumped, nh_virginrelnix is simultaneously set back
                 to zero.
        nix_t nh_virgrelnix - (see diagram)
                 relative node index within the segment identified by
                 nh_virgsegreloff of the next node not yet placed on the
                 free list. never reaches nh_nodesperseg: instead set
                 to zero and bump nh_virgsegreloff by one segment.

All the directory entries are stored in a node segment. Each segment holds around 1 million nodes (NODESPERSEGMIN). The value is greater because the size in bytes must be a multiple of the node size and the page size. However, the code handling the number of nodes was changed recently due to problems at a site. The number of nodes is now based on the value of dircnt+nondircnt in an attempt to fit most of the entries into 1 segment. As the value of dircnt+nondircnt is an approximation to the number of directory entries, we cap below at 1 million entries as was done previously.

Each segment is mmap'ed separately. In fact, the actual allocation of nodes is handled by a few abstractions. There is a node abstraction and a window abstraction. At the node abstraction when one wants to allocate a node using node_alloc(), one first checks the free-list of nodes. If the free list is empty then a new window is mapped and a chunk of 8192 nodes are put on the free list by linking each node using the first 8 bytes (ignoring node fields).

Window Abstraction
The window abstraction manages the mapping and unmapping of the segments (of nodes) of the dirent tree. In the node allocation, mentioned above, if our node-freelist is empty we call win_map() to map in a chunk of 8192 nodes for the node-freelist.

Consider the win_map(offset, return_memptr) function: 

One is asking for an offset within a segment.
It looks up its bag for the segment (given the offset), and 
if it's already mapped then 
    if the window has a refcnt of zero, then remove it from the win-freelist
    it uses that address within the mmap region and
    increments refcnt.
else if it's not in the bag then
    if win-freelist is not empty then
        munmap the oldest mapped segment
	remove head of win-freelist
        remove the old window from the bag 
    else /* empty free-list */
        allocate a new window
    endif
    mmap the segment
    increment refcnt
    insert window into bag of mapped segments
endif

The window abstraction maintains an LRU win-freelist not to be confused with the node-freelist. The win-freelist consists of windows (stored in a bag) which are doubly linked ordered by the time they were used. Whereas the node-freelist, is used to get a new node in the node allocation.

Note that the windows are stored in 2 lists. They are doubly linked in the LRU win-freelist and are also stored in a bag. A bag is just a doubly linked searchable list where the elements are allocated using calloc(). It uses the bag as a container of mmaped windows which can be searched using the bag key of window-offset. 


BAG:  |--------|     |--------|     |--------|     |--------|     |-------|
      | win A  |<--->| win B  |<--->| win C  |<--->| win D  |<--->| win E |
      | ref=2  |     | ref=1  |     | ref=0  |     | ref=0  |     | ref=0 |
      | offset |     | offset |     | offset |     | offset |     | offset|
      |--------|     |--------|     |--------|     |--------|     |-------|
                                      ^                               ^
                                      |                               |
                                      |                               |
                     |----------------|       |-----------------------|
LRU             |----|---|               |----|---|
win-freelist:   | oldest |               | 2nd    |
                | winptr |<------------->| oldest |<----....
                |        |               | winptr |

Call Chain
Below are some call chain scenarios of how the allocation of dirent tree nodes are done at different stages. 

1st time we allocate a dirent node:

applydirdump()
  Go thru each directory entry (dirent)
    tree_addent()
      if new entry then
         Node_alloc()
           node_alloc()
             win_map()
               mmap 1st segment/window
               insert win into bag
	       refcnt++
             make node-freelist of 8192 nodes (linked list)
             remove list node from freelist
             win_unmap()
               refcnt--
               put win on win-freelist (as refcnt==0)
             return node

2nd time we call tree_addent():

      if new entry then
         Node_alloc()
           node_alloc()
             get node off node-freelist (8190 nodes left now)
             return node
 
8193th time when we have used up 8192 nodes and node-freelist is emtpy:

      if new entry then
         Node_alloc()

Pseudo-code of snippets of directory tree creation functions (from notes) gives one an idea of the flow of control for processing dirents and adding to the tree and other auxiliary structures: 

content_stream_restore()
  ...
  Get next media file
  dirattr_init() - initialize directory attribute structure
  namereg_init() - initialize name registry structure
  tree_init() - initialize dirent tree
  applydirdump() - process the directory dump and create tree - see below
  treepost() - tree post processing where mkdirs happen
  ...

applydirdump()
  ...
  inomap_restore_pers() - read ino map 
  read directories and their entries
    loop 'til null hdr
       dirh = tree_begindir(fhdr, dah) - process dir filehdr
       loop 'til null entry
         rv = read_dirent()
         tree_addent(dirh, dhdrp->dh_ino, dh_gen, dh_name, namelen)
       endloop
       tree_enddir(dirh)
    endloop
  ...

tree_beginddir(fhdrp - fileheader, dahp - dirattrhandle)
  ...
  ino = fhdrp->fh_stat.bs_ino
  hardh = link_hardh(ino, gen) - lookup inode in tree
  if (hardh == NH_NULL) then
    new directory - 1st time seen
    dah = dirattr_add(fhdrp) - add dir header to dirattr structure
    hardh = Node_alloc(ino, gen,....,NF_ISDIR|NF_NEWORPH)
    link_in(hardh) - link into tree 
    adopt(p_orphh, hardh, NRH_NULL) - put dir in orphanage directory
  else
    ...
  endif

tree_addent(parent, inode, size, name, namelen)
  hardh = link_hardh(ino, gen)
  if (hardh == NH_NULL) then
    new entry - 1st time seen
    nrh = namreg_add(name, namelen)
    hardh = Node_alloc(ino, gen, NRH_NULL, DAH_NULL, NF_REFED)
    link_in(hardh)
    adopt(parent, hardh, nrh)
  else
    ...
  endif

Cumulative Restore

A cumulative restore seems a bit different than one might expect. It tries to restore the state of the filesystem at the time of the incremental dump. As the man page states: "This can involve adding, deleting, renaming, linking, and unlinking files and directories." From a coding point of view, this means we need to know what the dirent tree was like previously compared with what the dirent tree is like now. We need this so we can see what was added and deleted. So this means that the dirent tree, which is stored as an mmap'ed file in restoredir/xfsrestorehousekeepingdir/tree should not be deleted between cumulative restores (as we need to keep using it).

So on the first level 0 restore, the dirent tree is created. When the directories are restored and the files are restored, the corresponding tree nodes are marked as NF_REAL. On the next level cumulative restore, when it is processing the dirents, it looks them up in the tree (created on previous restore). If the entry alreadys exists then it marks it as NF_REFED.

In case a dirent has gone away between times of incremental dumps, xfsrestore does an extra pass in the tree preprocessing which traverses the tree looking for non-referenced (not NF_REFED) nodes so that if they exist in the FS (i.e. are NF_REAL) then they can be deleted (so that the FS resembles what it was at the time of the incremental dump). Note there are more conditionals to the code than just that - but that is the basic plan. It is elaborated further below.

Cumulative Restore Tree Postprocessing

After the dirent tree is created or updated from the directory dump cumulative restoral, it does a 4 step postprocessing (treepost):

Steps of Tree Postprocessing
FunctionWhat it does
1. noref_elim_recurse
  • remove deleted dirs
  • rename moved dirs to orphanage
  • remove extra deleted hard links
  • rename moved non-dirs to orphanage
2. mkdirs_recurse
  • mkdirs on (dir & !real & ref & sel)
3. rename_dirs
  • rename moved dirs from orphanage to destination
4. proc_hardlinks
  • rename moved non-dirs from orphanage to destination
  • remove deleted non-dirs (real & !ref & sel)
  • create a link on rename error (don't understand this one)

Step 1 was changed so that files which are deleted and not moved are deleted early on, otherwise, it can stop a parent directory from being deleted. The new step is:

FunctionWhat it does
1. noref_elim_recurse
  • remove deleted dirs
  • rename moved dirs to orphanage
  • remove extra deleted hard links
  • rename moved non-dirs to orphanage
  • remove deleted non-dirs which aren't part of a rename

One will notice that renames are not performed directly. Instead entries are renamed to the orphanage, directories are created, then entries are moved from the orphanage to the intended destination. This would be done as renames may not succeed until directories are created. And the directories are not created first as we may be able to create the entry by just moving an existing one. The step of "removing deleted non-dirs" in proc_hardlinks should not happen now since it is done earlier.

Partial Registry

The partial registry is a data structure used in xfsrestore for ensuring that files which have been split into multiple extent groups, do not restore the extended attributes until the entire file has been restored. The reason for this is apparently so that DMAPI attributes aren't restored until we have the complete file. Each extent group dumped has the identical copy of the extended attributes (EAs) for that file, thus without this data-structure we could apply the first EAs we come across.

The data structure is of the form: 

Array of M entries:
-------------------
0: inode#
   Array for each drive
     drive1:  
     ...
     driveN:  
-------------------
1: inode#
   Array for each drive
-------------------
2: inode#
   Array for each drive
-------------------
...
-------------------
M-1: inode#
     Array for each drive
-------------------

Where N = number of drives (streams); M = 2 * N - 1
There can only be 2*N-1 entries for the partial registry because each stream can contribute an entry for its current inode and one for a previous inode which is split - except for the 1st inode which cannot have a previous split. 
      stream 1        stream 2         stream 3      ...  stream N
  |---------------|----------------|-------------------|------------|
  |            ------   -----   ------   -----      -------  -----  |
  |            C  | P     C        | P     C           |  P    C    |
  |---------------|----------------|-------------------|------------|

       current       prev.+curr.        prev.+curr.      prev.+curr.

Where C = current; P = previous
So if an extent group is processed which doesn't cover the whole file, then the extent range for this file is updated with the partial registry. If the file doesn't exist in the array then a new entry is added. If the file does exist in the array then the extent group for the given drive is updated. It is worth remembering that one drive (stream) can have multiple extent groups (if it is >16Mb) in which case the extent group is just extended (they are split up in order).

A bug was discovered in this area of code, for DMF offline files which have an associated file size but no data blocks allocated and thus no extents. The Offline files were wrongly added to the partial registry because on restore they did not complete the size of the file (because they are offline!). These types of files which do not restore data are now special cased.

Drive Strategies

The I/O which happens when reading and writing the dump can be to a tape, file, stdout or to a tape remotely via rsh(1) (or $RSH) and rmt(1) (or $RMT). There are 3 pieces of code called strategies which handle the dump I/O:
  • drive_scsitape
  • drive_minrmt
  • drive_simple
There is an associated data structure - below is one for drive_scsitape: 
    drive_strategy_t drive_strategy_scsitape = {
	    DRIVE_STRATEGY_SCSITAPE,        /* ds_id */
	    "scsi tape (drive_scsitape)",   /* ds_description */
	    ds_match,                       /* ds_match */
	    ds_instantiate,                 /* ds_instantiate */
	    0x1000000ll,                    /* ds_recmarksep  16 MB */
	    0x10000000ll,                   /* ds_recmfilesz 256 MB */
    };
The choice of the strategy to use is done by a scoring scheme which is probably not warranted IMHO. (A direct cmd option would be simpler and less confusing.) The scoring function is called ds_match.
strategyIRIX scoringLinux scoring
drive_scsitape score badly with -10 if:
  • stdio pathname
  • if colon (':') in pathname (assumes remote) and
    • open on pathname fails
    • MTIOCGET ioctl fails
  • or not colon and drivername is not "tpsc" or "ts_"
else if syscalls complete ok then we score 10. 		score like IRIX but instead of checking drivername associated with path (not available on Linux), score -10 if the following:
  • stat fails
  • it is not a character device
  • its real path does not contain "/nst", "/st" nor "/mt".
drive_minrmt
  • score badly with -10 if stdio pathname
  • score 10 if have all of the following:
    • colon is in the pathname (assumes remote from this)
    • blocksize set with -b option
    • minrmt chosen with -m option
  • otherwise score badly with -10
score like IRIX but do not require a colon in the pathname; i.e. one can use this strategy on Linux without requiring a remote pathname
drive_simple
  • score badly with -1 if
    • stat fails on local pathname
    • pathname is a local directory
  • otherwise score with 1
identical to IRIX

Each strategy is organised like a "class" with functions/methods in the data structure: 

        do_init,                
        do_sync,                
        do_begin_read,          
        do_read,                
        do_return_read_buf,     
        do_get_mark,            
        do_seek_mark,           
        do_next_mark,           
        do_end_read,            
        do_begin_write,         
        do_set_mark,            
        do_get_write_buf,       
        do_write,               
        do_get_align_cnt,       
        do_end_write,           
        do_fsf,                 
        do_bsf,                 
        do_rewind,              
        do_erase,               
        do_eject_media,         
        do_get_device_class,    
        do_display_metrics,     
        do_quit,

Drive Scsitape

This strategy is the main one used for dumps to tape and dumps to a remote tape. This strategy on IRIX can be used for remote dumps to another IRIX machine. On Linux, this strategy is used for remote dumps to Linux or IRIX machines. Remote dumping uses the librmt library, see below.

If xfsdump/xfsrestore is running single-threaded (-Z option) or is running on Linux (which is not multi-threaded) then records are read/written straight to the tape. If it is running multi-threaded then a circular buffer is used as an intermediary between the client and slave threads.

Initially drive_init1() calls ds_instantiate() which if dump/restore is running multi-threaded, creates the ring buffer with ring_create which initialises the state to RING_STAT_INIT and sets up the slave thread with ring_slave_entry. 

ds_instantiate()
  ring_create(...,ring_read, ring_write,...)
    - allocate and init buffers
    - set rm_stat = RING_STAT_INIT
    start up slave thread with ring_slave_entry
The slave spends its time in a loop getting items from the active queue, doing the read or write operation and placing the result back on the ready queue. 
slave
======
ring_slave_entry()
  loop
    ring_slave_get() - get from active queue
    case rm_op
      RING_OP_READ -> ringp->r_readfunc
      RING_OP_WRITE -> ringp->r_writefunc
      ..
    endcase
    ring_slave_put() - puts on ready queue
  endloop

Reading
Prior to reading, one needs to call do_begin_read(), which calls prepare_drive(). prepare_drive() opens the tape drive if necessary and gets its status. It then works out the tape record size to use (set_best_blk_and_rec_sz) using current max blksize (mtinfo.maxblksz from ioctl(fd,MTIOCGETBLKINFO,minfo)) on the scsi tape device in IRIX.

On IRIX (from set_best_blk_and_rec_sz):

  • local tape -> tape_recsz = min(STAPE_MAX_RECSZ = 2 Mb, mtinfo.maxblksz)
    which typically would mean 2 Mb.
  • remote tape -> tape_recsz = STAPE_MIN_MAX_BLKSZ = 240 Kb

On Linux:

  • local tape ->
    • tape_recsz = STAPE_MAX_LINUX_RECSZ = 1 Mb
    • or if -b cmdlineblksize specified then
      tape_recsz = min(STAPE_MAX_RECSZ = 2 Mb, cmdlineblksize)
      which typically would mean cmdlineblksize.
  • remote tape -> tape_recsz = STAPE_MIN_MAX_BLKSZ = 240 Kb

If we have a fixed size device, then it tries to read initially at minimum(2Mb, current max blksize) but if it reads in a smaller number of bytes than this, then it will try again for STAPE_MIN_MAX_BLKSZ = 240 Kb data. 

prepare_drive()
  open drive (repeat & timeout if EBUSY)
  get tape status (repeat 'til timeout or online)
  set up tape rec size to try
  loop trying to read a record using straight Read()
      if variable blksize then
	 ok = nread>0 & !EOD & !EOT & !FileMark
      else fixed blksize then
	 ok = nread==tape_recsz & !EOD & !EOT & !FileMark
      endif
      if ok then 
	validate_media_file_hdr()
      else
        could be an error or try again with newsize
        (complicated logic in this code!)
      endif
  endloop

For each do_read call in the multi-threaded case, we have two sides to the story: the client which is coming from code in content.c and the slave which is a simple thread just satisfying I/O requests. From the point of view of the ring buffer, these are the steps which happen for reading:

  1. client removes msg from ready queue
  2. client wants to read, so sets op field to READ (RING_OP_READ) and puts on active queue
  3. slave removes msg from active queue, invokes client read function, sets status field: OK/ERROR, puts msg on ready queue
  4. client removes this msg from ready queue

The client read code looks like the following: 

client
======
do_read()
  getrec()
    singlethreaded -> read_record() -> Read()
    else -> 
      loop 'til contextp->dc_recp is set to a buffer
	Ring_get() -> ring.c/ring_get()
	  remove msg from ready queue
	      block on ready queue - qsemP( ringp->r_ready_qsemh )
	      msgp = &ringp->r_msgp[ ringp->r_ready_out_ix ];
	      cyclic_inc(ringp->r_ready_out_ix)
        case rm_stat: 
	  RING_STAT_INIT, RING_STAT_NOPACK, RING_STAT_IGNORE
            put read msg on active queue
		contextp->dc_msgp->rm_op = RING_OP_READ
		Ring_put(contextp->dc_ringp,contextp->dc_msgp);
          RING_STAT_OK
            contextp->dc_recp = contextp->dc_msgp->rm_bufp
          ...
        endcase
      endloop

Librmt

Librmt is a standard library on IRIX which provides a set of remote I/O functions:
  • rmtopen
  • rmtclose
  • rmtioctl
  • rmtread
  • rmtwrite
On linux, a librmt library is provided as part of the xfsdump distribution. The remote functions are used to dump/restore to remote tape drives on remote machines. It does this by using rsh or ssh to run rmt(1) on the remote machine. The main caveat, however, comes into play for the rmtioctl function. Unfortunately, the values for mt operations and status codes are different on different machines. For example, the offline command op on IRIX is 6 and on Linux it is 7. On Linux, 6 is rewind and on IRIX 7 is a no-op. So for the Linux xfsdump, the rmtiocl function has been rewritten to check what the remote OS is (e.g. rsh host uname) and do appropriate mappings of codes. As well as the different mt op codes, the mtget structures differ for IRIX and Linux and for Linux 32 bit and Linux 64 bit. The size of the mtget structure is used to determine which structure it is and the value of mt_type is used to determine if endian conversion needs to be done.

Drive Minrmt

The minrmt strategy was written based (copied) on the scsitape strategy. It has been simplified so that the state of the tape driver is not needed (i.e. status of EOT, BOT, EOD, FMK,... are not used) and the current blk size of the tape driver is not used. Instead error handling is based on the return codes from reading and writing and the blksize must be give as a parameter. It was designed for talking to remote NON-IRIX hosts where the status codes can vary. However, as was mentioned in the discussion of librmt on Linux, the mt operations vary on foreign hosts as well as the status codes. So this is only a limited solution.

Drive Simple

The simple strategy was designed for dumping to files or stdout. It is simpler in that it does NOT have to worry about:
  • the ring buffer
  • talking to the scsitape driver with various operations and status
  • multiple media files

Online Inventory

xfsdump keeps a record of previous xfsdump executions in the online inventory stored in /var/xfsdump/inventory or for Linux, /var/lib/xfsdump/inventory. This inventory is used to determine which previous dump a incremental dump should be based on. That is, when doing a level > 0 dump for a filesystem, xfsdump will refer to the online inventory to work out when the last dump for that filesystem was performed in order to work out which files will be included in the current dump. I believe the online inventory is also used by xfsrestore in order to determine which tapes will be needed to completely restore a dump.

xfsinvutil is a utility originally designed to remove unwanted information from the online inventory. Recently it has been beefed up to allow interactive browsing of the inventory and the ability to merge/import one inventory into another. (See Bug 818332.)

The inventory consists of three types of files:

Inventory files
Filename Description
fstab There is one fstab file which contains the list of filesystems that are referenced in the inventory.
*.InvIndex There is one InvIndex file per filesystem which contain pointers to the StObj files sorted temporaly.
*.StObj There may be many StObj files per filesystem. Each file contains information about, up to five, individual xfsdump executions. The information relates to what tapes were used, which inodes are stored in which media files, etc.

The files are constructed like so:

The data structures above converted to a block diagram look something like this:

The source code for accessing the inventory is contained in the inventory directory. The source code for xsfinvutil is contained in the invutil directory. xfsinvutil only uses some header files from the inventory directory for data structure definitions -- it uses its own code to access and modify the inventory.

Questions and Answers

How is -a and -z handled by xfsdump ?
If -a is NOT used then it looks like nothing special happens for files which have dmf state attached to them. So if the file uses too many blocks compared to our maxsize param (-z) then it will not get dumped. No inode nor data. The only evidence will be its entry in the inode map (which is dumped) which says its the state of a no-change-non-dir and the directory entry in the directories dump. The latter will mean that an ls in xfsrestore will show the file but it can not be restored.

If -a is used and the file has some DMF state then we do some magic. However, the magic really only seems to occur for dual-state files (or possibly also unmigrating files).

A file is marked as dual-state/unmigrating by looking at the DMF attribute, dmfattrp->state[1]. i.e = DMF_ST_DUALSTATE or DMF_ST_UNMIGRATING If this is the case, then we set, dmf_f_ctxtp->candidate = 1. If we have such a changed dual-state file then we mark it as changed in the inode-map so it can be dumped. If it is a dual state file, then its apparent size will be zero, so it will go onto the dumping stage.

When we go to dump the extents of the dual-state file, we do something different. We store the extents as only 1 extent which is a hole. I.e. this is the "NOT dumping data" bit.

When we go to dump the file-hdr of the dual-state file, we set, statp->bs_dmevmask |= (1< When we go to dump the extended-attributes of the dual-state file, we skip dumping the DMF attribute ones ! However, at the end of dumping the attributes, we then go and add a new DMF attribute for it: 

        dmfattrp->state[1] = DMF_ST_OFFLINE;
        *valuepp = (char *)dmfattrp;
        *namepp = DMF_ATTR_NAME;
        *valueszp = DMF_ATTR_LEN;

Summary:
  • dual state files (and unmigrating files) dumped with -a, cause magic to happen:
    • if file has changed then it will _always_ be marked to be dumped out (irrespective of file size/blocks)
    • its extent data will be dumped as 1 extent with a hole
    • its DMF attributes won't be dumped but a replacement DMF attribute will be dumped in its place
    • the stat buf's bs_devmask will be or'ed with DM_EVENT_READ
  • for all other cases, if the file has changed and its blocks cause it to exceed the maxsize param (-z) then the file will be marked as NOT-CHANGED in the inode map and so will NOT be dumped at all

How does it compute estimated dump size ?
A dump consists of media files (only 1 in the case of a dump to a file, and usually many when dumped to a tape (depending on device type)). A media file consists of:
  • global header
  • inode map (inode# + state(e.g.dump or not?) )
  • directories
  • non-directory files

A directory consists of a header, directory-entry-headers for its entries and extended-attribute header and attributes.

A non-directory file consists of a file header, extent-headers (for each extent), file data and extended-attribute header and attributes. Some types of files don't have extent headers or data.

The xfsdump code says: 

        size_estimate = GLOBAL_HDR_SZ
                        +
                        inomap_getsz( )
                        +
                        inocnt * ( u_int64_t )( FILEHDR_SZ + EXTENTHDR_SZ )
                        +
                        inocnt * ( u_int64_t )( DIRENTHDR_SZ + 8 )
                        +
                        datasz;
So this accounts for the:
  • global header
  • inode map
  • all the files
  • all the direntory entries ( "+8" presumably to account for average file name length range, where 8 chars already included in header; as this structure is padded to the next 8 byte boundary, it accounts for names with lengths between 8-15 chars)
  • data

What estimate doesn't seem to account for (that I can think of):

  • no extended attributes
  • assumes that a file will only have one extent
  • no tape block headers (for tape media)

"Datasz" is calculated by adding up for every regular inode file, its (number of data blocks) * (block size). However, if "-a" is used, then instead of doing this, if the file is dualstate/offline then the file's data won't be dumped and it adds zero for it.

Is the "dump size (non-dir files) : 910617928 bytes" the actual number of bytes it wrote to that tape ?
It is the number of bytes it wrote to the dump for the non-directory files' extents (not including file header nor extent header terminator). (I don't think this includes the tape block headers for a tape dump either.) It includes for each file:
  • any hole hdrs
  • alignment hdrs
  • alignment padding
  • extent headers for data
  • actual _data_ of extents
From code: 
    bytecnt += sizeof( filehdr_t );
    dump_extent_group(...,&bc,...);
	bytecnt = 0;
	bytecnt += sizeof( extenthdr_t );  /* extent header for hole */
	bytecnt += sizeof( extenthdr_t );  /* ext. alignment header */
	bytecnt += ( off64_t )cnt_to_align /* alignment padding */
	bytecnt += sizeof( extenthdr_t );  /* extent header for data */
	bytecnt += ( off64_t )actualsz;    /* actual extent data in file */  
	bytecnt += ( off64_t )reqsz; /* write padding to make up extent size */
    sc_stat_datadone += ( size64_t )bc;
It doesn't include the initial file header: 
    rv = dump_filehdr( ... );
    bytecnt += sizeof( filehdr_t );
nor the extent hdr terminator: 
    rv = dump_extenthdr( ..., EXTENTHDR_TYPE_LAST,...);
    bytecnt += sizeof( extenthdr_t );
    contextp->cc_mfilesz += bytecnt;
It only adds this data size into the media file size.

Outstanding Questions

  • How is the inode map on the tape used by xfsrestore ?
  • Is the final inventory media file on the media ever used/restored ?
  • How are tape marks used and written ?
  • What is the difference between a record and a block ?
    • I don't think there is a difference.
  • Where are tape_recsz and tape_blksz used ?
    • Tape_recsz is used for the read/write byte cnt but I don't think tape_blksz is used.
  • What is the persistent inventory used for ?

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. ---------------------------------------------------------------------- xfsdump-3.1.6+nmu1/doc/INSTALL0000644000000000000000000000275012607344125012557 0ustar This document describes how to configure and build the open source XFS commands and utilites ("xfsdump") from source, and how to install and run them. 0. If you have the binary rpm, simply install it and skip to step 2 (below). The rpm command to do this is: # rpm -Uvh xfsdump The Debian command to do this is: # dpkg -i xfsdump or, if you have apt configured (don't need the binary package): # apt-get install xfsdump 1. Configure, build and install the package The xfsdump package uses autoconf/configure and expects a GNU build environment (your platform must at least have both autoconf and gmake). You will also need to have installed either the e2fsprogs-devel package (on an RPM based system) or the uuid-dev package (on a Debian system) as some of the commands make use of the UUID library provided by these. To build the package and install it manually, use the following steps: # make # su root # make install [and optionally, for the development libraries and headers] # make install-dev Note that there are so many "install" variants out there that we wrote our own script (see "install-sh" in the top level directory). If you wish to turn off debugging asserts in the command build and turn on the optimizer then set the shell environment variables: OPTIMIZER=-O1 DEBUG=-DNDEBUG before running make or Makepkgs. 2.

.in .. .SH DESCRIPTION .I xfsdump backs up files and their attributes in a filesystem. The files are dumped to storage media, a regular file, or standard output. Options allow the operator to have all files dumped, just files that have changed since a previous dump, or just files contained in a list of pathnames. .P The .IR xfsrestore (8) utility re-populates a filesystem with the contents of the dump. .P Each invocation of .I xfsdump dumps just one filesystem. That invocation is termed a dump session. The dump session splits the filesystem into one or more dump streams, one per destination. The split is done in filesystem inode number (ino) order, at boundaries selected to equalize the size of each stream. Furthermore, the breakpoints between streams may be in the middle of very large files (at extent boundaries) if necessary to achieve reasonable stream size equalization. Each dump stream can span several media objects, and a single media object can contain several dump streams. The typical media object is a tape cartridge. The media object records the dump stream as one or more media files. A media file is a self-contained partial dump, intended to minimize the impact of media dropouts on the entire dump stream at the expense of increasing the time required to complete the dump. By default only one media file is written unless a media file size is specified using the .B \-d option. Other techniques, such as making a second copy of the dump image, provide more protection against media failures than multiple media files will. .P .I xfsdump maintains an online dump inventory in \f2/var/lib/xfsdump/inventory\f1. The .B \-I option displays the inventory contents hierarchically. The levels of the hierarchy are: filesystem, dump session, stream, and media file. .P The options to .I xfsdump are: .TP 5 .B \-a Specifies that files for which the Data Migration Facility (DMF) has complete offline copies (dual-state files) be treated as if they were offline (OFL). This means that the file data will not be dumped by xfsdump, resulting in a smaller dump file. If the file is later restored the file data is still accessible through DMF. If both '\-a option' and '\-z option' are specified, the '\-a option' takes precedence (see '\-z option' below). .TP 5 \f3\-b\f1 \f2blocksize\f1 Specifies the blocksize, in bytes, to be used for the dump. The same blocksize must be specified to restore the tape. If the \f3\-m\f1 option is not used, then \f3\-b\f1 does not need to be specified. Instead, a default blocksize of 1Mb will be used. .TP 5 \f3\-c\f1 \f2progname\f1 Use the specified program to alert the operator when a media change is required. The alert program is typically a script to send a mail or flash a window to draw the operator's attention. .TP 5 \f3\-d\f1 \f2filesize\f1 Specifies the size, in megabytes, of dump media files. If not specified, xfsdump will dump data to tape using a single media file per media object. The specified media file size may need to be adjusted if, for example, xfsdump cannot fit a media file onto a single tape. .TP 5 \f3\-e\f1 Allow files to be excluded from the dump. This will cause xfsdump to skip files which have the "no dump" file attribute set. See the "Excluding individual files" section below for details on setting this file attribute. .TP 5 \f3\-f\f1 \f2dest\f1 [ \f3\-f\f1 \f2dest\f1 ... ] Specifies a dump destination. A dump destination can be the pathname of a device (such as a tape drive), a regular file or a remote tape drive (see \f2rmt\f1(8)). This option must be omitted if the standard output option (a lone .B \- preceding the source filesystem specification) is specified. .TP 5 \f3\-l\f1 \f2level\f1 Specifies a dump level of 0 to 9. The dump level determines the base dump to which this dump is relative. The base dump is the most recent dump at a lesser level. A level 0 dump is absolute \- all files are dumped. A dump level where 1 <= \f2level\f1 <= 9 is referred to as an incremental dump. Only files that have been changed since the base dump are dumped. Subtree dumps (see the .B \-s option below) cannot be used as the base for incremental dumps. .TP 5 .B \-m Use the minimal tape protocol for non-scsi tape destinations or remote tape destinations which are not scsi Linux tape drives nor IRIX tape drives. This option cannot be used without specifying a blocksize to be used (see .B \-b option above). .TP 5 .B \-o Overwrite the tape. With this option, .I xfsdump does not read the tape first to check the contents. This option may be used if .I xfsdump is unable to determine the block size of a tape . .TP 5 \f3\-p\f1 \f2interval\f1 Causes progress reports to be printed at the specified interval. .I interval is given in seconds. The progress report indicates how many files have been dumped, the total number of files to dump, the percentage of data dumped, and the elapsed time. .TP 5 \f3\-q\f1 Destination tape drive is a QIC tape. QIC tapes only use a 512 byte blocksize, for which \f2xfsdump\f1 must make special allowances. .TP 5 \f3\-s\f1 \f2pathname\f1 [ \f3\-s\f1 \f2pathname\f1 ... ] Restricts the dump to files contained in the specified pathnames (subtrees). A \f2pathname\f1 must be relative to the mount point of the filesystem. For example, if a filesystem is mounted at \f2/d2\f1, the \f2pathname\f1 argument for the directory \f2/d2/users\f1 is ``users''. A \f2pathname\f1 can be a file or a directory; if it is a directory, the entire hierarchy of files and subdirectories rooted at that directory is dumped. Subtree dumps cannot be used as the base for incremental dumps (see the .B \-l option above). .TP 5 \f3\-t\f1 \f2file\f1 Sets the dump time to the modification time of \f2file\f1 rather than using the current time. .I xfsdump uses the dump time to determine what files need to be backed up during an incremental dump. This option should be used when dumping snapshots so that the dump time matches the time the snapshot was taken. Otherwise files modified after a snapshot is taken may be skipped in the next incremental dump. .TP 5 \f3\-v\f1 \f2verbosity\f1 .PD 0 .TP 5 \f3\-v\f1 \f2subsys\f1=\f2verbosity\f1[,\f2subsys\f1=\f2verbosity\f1,...] .PD Specifies the level of detail used for messages displayed during the course of the dump. The \f2verbosity\f1 argument can be passed as either a string or an integer. If passed as a string the following values may be used: \f3silent\f1, \f3verbose\f1, \f3trace\f1, \f3debug\f1, or \f3nitty\f1. If passed as an integer, values from 0\-5 may be used. The values 0\-4 correspond to the strings already listed. The value 5 can be used to produce even more verbose debug output. The first form of this option activates message logging across all dump subsystems. The second form allows the message logging level to be controlled on a per-subsystem basis. The two forms can be combined (see the example below). The argument \f2subsys\f1 can take one of the following values: \f3general\f1, \f3proc\f1, \f3drive\f1, \f3media\f1, \f3inventory\f1, \f3inomap\f1 and \f3excluded_files\f1. For example, to dump the root filesystem with tracing activated for all subsystems: .EX # xfsdump \-v trace \-f /dev/tape / .EE To enable debug-level tracing for drive and media operations: .EX # xfsdump \-v drive=debug,media=debug \-f /dev/tape / .EE To enable tracing for all subsystems, and debug level tracing for drive operations only: .EX # xfsdump \-v trace,drive=debug \-f /dev/tape / .EE To list files that will be excluded from the dump: .EX # xfsdump \-e \-v excluded_files=debug \-f /dev/tape / .EE .TP 5 \f3\-z\f1 \f2size\f1 Specifies the maximum size, in kilobytes, of files to be included in the dump. Files over this size, will be excluded from the dump, except for DMF dual-state files when '\-a option' is specified (see '\-a option' above). When specified, '\-a option' takes precedence over '\-z option'. The size is an estimate based on the number of disk blocks actually used by the file, and so does not include holes. In other words, size refers to the amount of space the file would take in the resulting dump. On an interactive restore, the skipped file is visible with xfsrestore's 'ls' and while you can use the 'add' and 'extract' commands, nothing will be restored. .TP 5 .B \-A Do not dump extended file attributes. When dumping a filesystem managed within a DMF environment this option should not be used. DMF stores file migration status within extended attributes associated with each file. If these attributes are not preserved when the filesystem is restored, files that had been in migrated state will not be recallable by DMF. Note that dumps containing extended file attributes cannot be restored with older versions of \f2xfsrestore\f1(8). .TP 5 \f3\-B\f1 \f2session_id\f1 Specifies the ID of the dump session upon which this dump session is to be based. If this option is specified, the .B \-l (level) and .B \-R (resume) options are not allowed. Instead, .B xfsdump determines if the current dump session should be incremental and/or resumed, by looking at the base session's level and interrupted attributes. If the base session was interrupted, the current dump session is a resumption of that base at the same level. Otherwise, the current dump session is an incremental dump with a level one greater than that of the base session. This option allows incremental and resumed dumps to be based on any previous dump, rather than just the most recent. .TP 5 .B \-D Controls which directories are backed up during an incremental dump. By default unchanged directories are dumped if files or directories beneath them have changed. This results in a self-contained dump -- if a base dump is lost, or you know the file(s) you wish to restore is in an incremental dump, you can restore just that dump without loading the base dump(s) first. However, this method requires a potentially expensive traversal through the filesystem. When .B \-D is specified, unchanged directories are not dumped. This results in a faster dump, but files will end up in the .IR xfsrestore (8) .I orphanage directory unless the base dump(s) is loaded first. .TP 5 .B \-E Pre-erase media. If this option is specified, media is erased prior to use. The operator is prompted for confirmation, unless the .B \-F option is also specified. .TP 5 .B \-F Don't prompt the operator. When .I xfsdump encounters a media object containing non-xfsdump data, .I xfsdump normally asks the operator for permission to overwrite. With this option the overwrite is performed, no questions asked. When .I xfsdump encounters end-of-media during a dump, .I xfsdump normally asks the operator if another media object will be provided. With this option the dump is instead interrupted. .TP 5 .B \-I Displays the \f2xfsdump\f1 inventory (no dump is performed). .I xfsdump records each dump session in an online inventory in \f2/var/lib/xfsdump/inventory\f1. .I xfsdump uses this inventory to determine the base for incremental dumps. It is also useful for manually identifying a dump session to be restored. Suboptions to filter the inventory display are described later. .TP 5 .B \-J Inhibits the normal update of the inventory. This is useful when the media being dumped to will be discarded or overwritten. .TP 5 .B \-K Generate a format 2 dump instead of the current format. This is useful if the dump will be restored on a system with an older .I xfsrestore which does not understand the current dump format. Use of this option is otherwise not recommended. .TP 5 \f3\-L\f1 \f2session_label\f1 Specifies a label for the dump session. It can be any arbitrary string up to 255 characters long. .TP 5 \f3\-M\f1 \f2label\f1 [ \f3\-M\f1 \f2label\f1 ... ] Specifies a label for the first media object (for example, tape cartridge) written on the corresponding destination during the session. It can be any arbitrary string up to 255 characters long. Multiple media object labels can be specified, one for each destination. .TP 5 \f3\-O\f1 \f2options_file\f1 Insert the options contained in \f2options_file\f1 into the beginning of the command line. The options are specified just as they would appear if typed into the command line. In addition, newline characters (\en) can be used as whitespace. The options are placed before all options actually given on the command line, just after the command name. Only one \f3\-O\f1 option can be used. Recursive use is ignored. The source filesystem cannot be specified in \f2options_file\f1. .TP 5 .B \-R Resumes a previously interrupted dump session. If the most recent dump at this dump's level (\f3\-l\f1 option) was interrupted, this dump contains only files not in the interrupted dump and consistent with the incremental level. However, files contained in the interrupted dump that have been subsequently modified are re-dumped. .TP 5 .B \-T Inhibits interactive dialogue timeouts. When the .B \-F option is not specified, .I xfsdump prompts the operator for labels and media changes. Each dialogue normally times out if no response is supplied. This option prevents the timeout. .TP 5 \f3\-Y\f1 \f2length\f1 Specify I/O buffer ring length. .I xfsdump uses a ring of output buffers to achieve maximum throughput when dumping to tape drives. The default ring length is 3. However, this is not currently enabled on Linux yet, making this option benign. .TP 5 .B \- A lone .B \- causes the dump stream to be sent to the standard output, where it can be piped to another utility such as \f2xfsrestore\f1(8) or redirected to a file. This option cannot be used with the .B \-f option. The .B \- must follow all other options and precede the filesystem specification. .P The filesystem, \f2filesystem\f1, can be specified either as a mount point or as a special device file (for example, \f2/dev/dsk/dks0d1s0\f1). The filesystem must be mounted to be dumped. .SH NOTES .SS Dump Interruption A dump can be interrupted at any time and later resumed. To interrupt, type control-C (or the current terminal interrupt character). The operator is prompted to select one of several operations, including dump interruption. After the operator selects dump interruption, the dump continues until a convenient break point is encountered (typically the end of the current file). Very large files are broken into smaller subfiles, so the wait for the end of the current file is brief. .SS Dump Resumption A previously interrupted dump can be resumed by specifying the .B \-R option. If the most recent dump at the specified level was interrupted, the new dump does not include files already dumped, unless they have changed since the interrupted dump. .SS Media Management A single media object can contain many dump streams. Conversely, a single dump stream can span multiple media objects. If a dump stream is sent to a media object already containing one or more dumps, .I xfsdump appends the new dump stream after the last dump stream. Media files are never overwritten. If end-of-media is encountered during the course of a dump, the operator is prompted to insert a new media object into the drive. The dump stream continuation is appended after the last media file on the new media object. .SS Inventory Each dump session updates an inventory database in \f2/var/lib/xfsdump/inventory\f1. .I xfsdump uses the inventory to determine the base of incremental and resumed dumps. .P This database can be displayed by invoking .I xfsdump with the .B \-I option. The display uses tabbed indentation to present the inventory hierarchically. The first level is filesystem. The second level is session. The third level is media stream (currently only one stream is supported). The fourth level lists the media files sequentially composing the stream. .P The following suboptions are available to filter the display. .TP 5 \f3\-I depth=\f1\f2n\f1 (where .I n is 1, 2, or 3) limits the hierarchical depth of the display. When .I n is 1, only the filesystem information from the inventory is displayed. When .I n is 2, only filesystem and session information are displayed. When .I n is 3, only filesystem, session and stream information are displayed. .TP 5 \f3\-I level=\f1\f2n\f1 (where .I n is the dump level) limits the display to dumps of that particular dump level. .P The display may be restricted to media files contained in a specific media object. .TP 5 \f3\-I mobjid=\f1\f2value\f1 (where .I value is a media ID) specifies the media object by its media ID. .TP 5 \f3\-I mobjlabel=\f1\f2value\f1 (where .I value is a media label) specifies the media object by its media label. .P Similarly, the display can be restricted to a specific filesystem. .TP 5 \f3\-I mnt=\f1\f2mount_point\f1 (that is, [hostname:]pathname), identifies the filesystem by mountpoint. Specifying the hostname is optional, but may be useful in a clustered environment where more than one host can be responsible for dumping a filesystem. .TP 5 \f3\-I fsid=\f1\f2filesystem_id\f1 identifies the filesystem by filesystem ID. .TP 5 \f3\-I dev=\f1\f2device_pathname\f1 (that is, [hostname:]device_pathname) identifies the filesystem by device. As with the .B mnt filter, specifying the hostname is optional. .P More than one of these suboptions, separated by commas, may be specified at the same time to limit the display of the inventory to those dumps of interest. However, at most four suboptions can be specified at once: one to constrain the display hierarchy depth, one to constrain the dump level, one to constrain the media object, and one to constrain the filesystem. .P For example, .B \-I depth=1,mobjlabel="tape 1",mnt=host1:/test_mnt would display only the filesystem information (depth=1) for those filesystems that were mounted on \f2host1:/test_mnt\f1 at the time of the dump, and only those filesystems dumped to the media object labeled "tape 1". .P Dump records may be removed (pruned) from the inventory using the .I xfsinvutil program. .P An additional media file is placed at the end of each dump stream. This media file contains the inventory information for the current dump session. Its contents may be merged back into the online inventory database at a later time using .IR xfsrestore (1M). .P The inventory files stored in .I /var/lib/xfsdump are not included in the dump, even if that directory is contained within the filesystem being dumped. Including the inventory in the dump may lead to loss or corruption of data, should an older version be restored overwriting the current version. To backup the .I xfsdump inventory, the contents of .I /var/lib/xfsdump should be copied to another location which may then be safely dumped. Upon restoration, those files may be copied back into .IR /var/lib/xfsdump , overwriting whatever files may be there, or .IR xfsinvutil (1M) may be used to selectively merge parts of the restored inventory back into the current inventory. Prior to version 1.1.8, .I xfsdump would include the .I /var/lib/xfsdump directory in the dump. Care should be taken not to overwrite the .I /var/lib/xfsdump directory when restoring an old dump, by either restoring the filesystem to another location or by copying the current contents of .I /var/lib/xfsdump to a safe place prior to running .IR xfsrestore (1M). .P .SS Labels The operator can specify a label to identify the dump session and a label to identify a media object. The session label is placed in every media file produced in the course of the dump, and is recorded in the inventory. .P The media label is used to identify media objects, and is independent of the session label. Each media file on the media object contains a copy of the media label. An error is returned if the operator specifies a media label that does not match the media label on a media object containing valid media files. Media labels are recorded in the inventory. .SS UUIDs UUIDs (Universally Unique Identifiers) are used in three places: to identify the filesystem being dumped (using the filesystem UUID, see .IR xfs (5) for more details), to identify the dump session, and to identify each media object. The inventory display (\f3\-I\f1) includes all of these. .SS Dump Level Usage The dump level mechanism provides a structured form of incremental dumps. A dump of level \f2level\f1 includes only files that have changed since the most recent dump at a level less than \f2level\f1. For example, the operator can establish a dump schedule that involves a full dump every Friday and a daily incremental dump containing only files that have changed since the previous dump. In this case Friday's dump would be at level 0, Saturday's at level 1, Sunday's at level 2, and so on, up to the Thursday dump at level 6. .P The above schedule results in a very tedious restore procedure to fully reconstruct the Thursday version of the filesystem; \f2xfsrestore\f1 would need to be fed all 7 dumps in sequence. A compromise schedule is to use level 1 on Saturday, Monday, and Wednesday, and level 2 on Sunday, Tuesday, and Thursday. The Monday and Wednesday dumps would take longer, but the worst case restore requires the accumulation of just three dumps, one each at level 0, level 1, and level 2. .SS Quotas If the filesystem being dumped contains user quotas, .I xfsdump will use .IR xfs_quota (8) to store the quotas in a file called .I xfsdump_quotas in the root of the filesystem to be dumped. This file will then be included in the dump. Upon restoration, .I xfs_quota (8) can be used to reactivate the quotas for the filesystem. Note, however, that the .I xfsdump_quotas file will probably require modification to change the filesystem or UIDs if the filesystem has been restored to a different partition or system. Group and project quotas will be handled in a similar fashion and saved in files called .I xfsdump_quotas_group and .I xfsdump_quotas_proj , respectively. .SS Excluding individual files It may be desirable to exclude particular files or directories from the dump. The .B -s option can be used to limit the dump to a specified directory, and the .B -z option can be used to exclude files over a particular size. Additionally, when .I xfsdump is run with the .B -e option, files that are tagged with the "no dump" file attribute will not be included in the dump. The .IR chattr (1) command can be used to set this attribute on individual files or entire subtrees. To tag an individual file for exclusion from the dump: .EX $ chattr +d file .EE To tag all files in a subtree for exclusion from the dump: .EX $ chattr \-R +d directory .EE Note that any new files or directories created in a directory which has the "no dump" attribute set will automatically inherit this attribute. Also note that .I xfsdump does not check directories for the "no dump" attribute. .PP Care should be taken to note which files have been tagged. Under normal operation, .I xfsdump will only report the number of files it will skip. The .B "\-v excluded_files=debug" option, however, will cause .I xfsdump to list the inode numbers of the individual files affected. .SH EXAMPLES To perform a level 0, single stream dump of the root filesystem to a locally mounted tape drive, prompting for session and media labels when required: .EX # xfsdump \-f /dev/tape / .EE To specify session and media labels explicitly: .EX # xfsdump \-L session_1 \-M tape_0 \-f /dev/tape / .EE To perform a dump to a remote tape using the minimal rmt protocol and a set blocksize of 64k: .EX # xfsdump \-m \-b 65536 \-f otherhost:/dev/tape / .EE To perform a level 0, multi-stream dump to two locally mounted tape drives: .EX # xfsdump \-L session_2 \-f /dev/rmt/tps4d6v \-M tape_1 \e \-f /dev/rmt/tps5d6v \-M tape_2 / .EE To perform a level 1 dump relative to the last level 0 dump recorded in the inventory: .EX # xfsdump \-l 1 \-f /dev/tape / .EE To copy the contents of a filesystem to another directory (see \f2xfsrestore\f1(8)): .EX # xfsdump \-J \- / | xfsrestore \-J \- /new .EE .SH FILES .TP 25 /var/lib/xfsdump/inventory dump inventory database .SH SEE ALSO attr(1), rmt(8), xfsrestore(8), xfsinvutil(8), xfs_quota(8), attr_get(2). .SH DIAGNOSTICS The exit code is 0 on normal completion, non-zero if an error occurs or the dump is terminated by the operator. .P For all verbosity levels greater than 0 (\f3silent\f1) the final line of the output shows the exit status of the dump. It is of the form: .EX xfsdump: Dump Status: \f2code\f1 .EE Where \f2code\f1 takes one of the following values: \f3SUCCESS\f1 (normal completion), \f3INTERRUPT\f1 (interrupted), \f3QUIT\f1 (media no longer usable), \f3INCOMPLETE\f1 (dump incomplete), \f3FAULT\f1 (software error), and \f3ERROR\f1 (resource error). Every attempt will be made to keep both the syntax and the semantics of this log message unchanged in future versions of xfsdump. However, it may be necessary to refine or expand the set of exit codes, or their interpretation at some point in the future. .PP The message ``xfsdump: WARNING: unable to open directory: ino N: Invalid argument'' can occur with filesystems which are actively being modified while .I xfsdump is running. This can happen to either directory or regular file inodes \- affected files will not end up in the dump, files below affected directories will be placed in the .I orphanage directory by .IR xfsrestore . .SH BUGS .I xfsdump does not dump unmounted filesystems. .PP The dump frequency field of \f2/etc/fstab\f1 is not supported. .PP .I xfsdump uses the alert program only when a media change is required. .PP .I xfsdump requires root privilege (except for inventory display). .PP .I xfsdump can only dump XFS filesystems. .PP The media format used by \f2xfsdump\f1 can only be understood by \f2xfsrestore\f1. .PP \f2xfsdump\f1 does not know how to manage CD-ROM or other removable disk drives. .PP \f2xfsdump\f1 can become confused when doing incremental or resumed dumps if on the same machine you dump two XFS filesystems and both filesystems have the same filesystem identifier (UUID). Since \f2xfsdump\f1 uses the filesystem identifier to identify filesystems, \f2xfsdump\f1 maintains one combined set of dump inventories for both filesystems instead of two sets of dump inventories. This scenario can happen only if .I dd or some other block-by-block copy program was used to make a copy of an XFS filesystem.

The .B \-I option of xfsdump displays the inventory contents hierarchically. The levels of the hierarchy are: filesystem, dump session, stream, and media file. .P .I xfsinvutil is a utility to check this inventory database for consistency, to remove entries of dump sessions which may no longer be of relevance, and to browse the contents of the inventory. .P The following command line options are available: .TP 5 \f3\-F\f1 Don't prompt the operator. When .I xfsinvutil encounters a matching dump session, .I xfsinvutil will normally ask the operator for permission to delete the entry. With this option the deletion is performed, no questions asked. .TP 5 \f3\-i\f1 Interactive mode. Causes .I xfsinvutil to run in a mode that will allow the operator to browse and modify the contents of the inventory. Please refer to the .B "Interactive Mode" section below for more information. .TP 5 \f3\-M\f1 \f2mount_point mm/dd/yyyy\f1 Prunes dump sessions identified by the given mount point which were created prior to the specified date. Optionally \f3\-m\f1 may be be specified to further limit the matching dump sessions by media label. .I xfsinvutil will prompt the operator prior to pruning a dump session unless the \f3\-F\f1 or \f3\-i\f1 options are given. .TP 5 \f3\-u\f1 \f2UUID mm/dd/yyyy\f1 Like \f3\-M\f1, except the matching filesystem is specified using its universally unique identifier (UUID) instead of its mount point. .TP 5 \f3\-m\f1 \f2media_label\f1 If specified, only sessions with at least one media file whose label matches this value will be eligible for pruning. This restriction is in addition to those imposed by the date and the \f3\-M\f1 or \f3\-u\f1 options. This option allows the pruning of all inventory references to media which may have been overwritten or lost. Note that this option does not apply to sessions with no media files. .TP 5 \f3\-s\f1 \f2SESSION_ID\f1 Prunes the dump session identified by the given session id. .I xfsinvutil will prompt the operator prior to pruning a dump session unless the \f3\-F\f1 option is given. .TP 5 .B \-C With this option, .I xfsinvutil performs consistency checks for all entries in the inventory database. It fixes any problems found. If no consistent entries are found , the corresponding inventory database file is removed. .SS Interactive Mode When run with \f3-i\f1, .I xfsinvutil will present the operator with a hierarchical representation of the .I xfsdump inventory. In this mode, the operator can use the arrow keys (or the .B h .B j .B k .B l keys) to navigate the inventory and also use the following keys and functionality: .TP 5 \f3+\f1 Expand a branch of the tree. .TP 5 \f3-\f1 Collapse a branch of the tree. .TP 5 \f3*\f1 Fully expand a branch of the tree. .TP 5 \f3%\f1 Fully collapse a branch of the tree. .TP 5 \f3h\f1 Move selection to the parent entry. .TP 5 \f3l\f1 Move selection to the child entry. .TP 5 \f3j\f1 Move selection to next entry. .TP 5 \f3k\f1 Move selection to previous entry. .TP 5 \f3d\f1 Mark the current record, and all sub-records, to be deleted. .TP 5 \f3u\f1 Clear the current record and all parent records from being deleted. .TP 5 \f3i\f1 Import another .I xfsdump inventory. .TP 5 \f3?\f1 Show help window. .TP 5 \f3x\f1 Commit any changes made to the inventory, and exit the program. .TP 5 \f3q\f1 Exit the program without committing any changes to the inventory. .P Inventories from other hosts can be imported to create a larger common inventory. It is recommended that the contents of .I /var/lib/xfsdump/inventory on the remote host be copied to a temporary local directory prior to running .IR xfsinvutil . When .I xfsinvutil is run in interactive mode, and the operator hits .BR i , they will be prompted for the path to the inventory to be imported. .I xfsinvutil will then add the contents of the imported inventory to the main window, and all entries will be marked as imported. The operator can then delete any of these entries that are not to be imported. When the operator commits the changes, .I xfsinvutil will import any entries which were not marked as deleted. Deleted entries are not actually deleted from the original imported inventory. .SH NOTES .SS Inventory Each dump session updates an inventory database in \f2/var/lib/xfsdump/inventory\f1. .I xfsdump uses the inventory to determine the base of incremental and resumed dumps. .P This database can be displayed by invoking .I xfsdump with the .B \-I option. The display uses tabbed indentation to present the inventory hierarchically. The first level is filesystem. The second level is session. The third level is media stream (currently only one stream is supported). The fourth level lists the media files sequentially composing the stream. .SH FILES .TP 25 /var/lib/xfsdump/inventory dump inventory database .SH SEE ALSO xfsdump(8), xfsrestore(8). xfsdump-3.1.6+nmu1/man/man8/xfsrestore.80000644000000000000000000006135412607344125014701 0ustar .TH xfsrestore 8 .SH NAME xfsrestore \- \&XFS filesystem incremental restore utility .SH SYNOPSIS .nf \f3xfsrestore\f1 \-h \f3xfsrestore\f1 [ options ] \-f \f2source\f1 [ \-f \f2source\f1 ... ] \f2dest\f1 \f3xfsrestore\f1 [ options ] \- \f2dest\f1 \f3xfsrestore\f1 \-I [ subopt=value ... ] .fi .\" .\" Macro EX: bold constant width example .de EX \" start bold constant width .in +.5i .ie t .ft CB .el .ft B .ie t .sp .5v .el .sp .ta \\w' 'u*8 .nf .. .de EE \" end bold constant width .fi .ie t .sp .5v .el .sp .ft R .in .. .SH DESCRIPTION .I xfsrestore restores filesystems from dumps produced by \f2xfsdump\f1(8). Two modes of operation are available: simple and cumulative. .P The default is simple mode. .I xfsrestore populates the specified destination directory, \f2dest\f1, with the files contained in the dump media. .P The .B \-r option specifies the cumulative mode. Successive invocations of .I xfsrestore are used to apply a chronologically ordered sequence of delta dumps to a base (level 0) dump. The contents of the filesystem at the time each dump was produced is reproduced. This can involve adding, deleting, renaming, linking, and unlinking files and directories. .P A delta dump is defined as either an incremental dump (\f2xfsdump\f1 .B \-l option with level > 0) or a resumed dump (\f2xfsdump\f1 .B \-R option). The deltas must be applied in the order they were produced. Each delta applied must have been produced with the previously applied delta as its base. .P .I xfsrestore keeps state information in the .IR xfsrestorehousekeepingdir , to inform subsequent invocations when used in cumulative mode, or in the event a restore is interrupted. To ensure that the state information can be processed, a compatible version of .I xfsrestore must be used for each subsequent invocation. Additionally, each invocation must run on a system of the same endianness and page size. .P The options to .I xfsrestore are: .TP 5 \f3\-a\f1 \f2housekeeping\f1 Each invocation of \f2xfsrestore\f1 creates a directory called .IR xfsrestorehousekeepingdir . This directory is normally created directly under the \f2dest\f1 directory. The .B \-a option allows the operator to specify an alternate directory, \f2housekeeping\f1, in which .I xfsrestore creates the .I xfsrestorehousekeepingdir directory. When performing a cumulative (\f3\-r\f1 option) restore or resuming (\f3\-R\f1 option) a restore, each successive invocation must specify the same alternate directory. .TP 5 \f3\-b\f1 \f2blocksize\f1 Specifies the blocksize, in bytes, to be used for the restore. For other drives such as DAT or 8 mm , the same blocksize used for the xfsdump operation must be specified to restore the tape. The default block size is 1Mb. .TP 5 \f3\-c\f1 \f2progname\f1 Use the specified program to alert the operator when a media change is required. The alert program is typically a script to send a mail or flash a window to draw the operator's attention. .TP 5 \f3\-e\f1 Prevents .I xfsrestore from overwriting existing files in the \f2dest\f1 directory. .TP 5 \f3\-f\f1 \f2source\f1 [ \f3\-f\f1 \f2source\f1 ... ] Specifies a source of the dump to be restored. This can be the pathname of a device (such as a tape drive), a regular file or a remote tape drive (see \f2rmt\f1(8)). This option must be omitted if the standard input option (a lone .B \- preceding the \f2dest\f1 specification) is specified. .TP 5 .B \-i Selects interactive operation. Once the on-media directory hierarchy has been read, an interactive dialogue is begun. The operator uses a small set of commands to peruse the directory hierarchy, selecting files and subtrees for extraction. The available commands are given below. Initially nothing is selected, except for those subtrees specified with \f3\-s\f1 command line options. .RS .TP 15 \f3ls\f1 [\f2arg\f1] List the entries in the current directory or the specified directory, or the specified non-directory file entry. Both the entry's original inode number and name are displayed. Entries that are directories are appended with a `/'. Entries that have been selected for extraction are prepended with a `*'. .TP \f3cd\f1 [\f2arg\f1] Change the current working directory to the specified argument, or to the filesystem root directory if no argument is specified. .TP \f3pwd\f1 Print the pathname of the current directory, relative to the filesystem root. .TP \f3add\f1 [\f2arg\f1] The current directory or specified file or directory within the current directory is selected for extraction. If a directory is specified, then it and all its descendents are selected. Entries that are selected for extraction are prepended with a `*' when they are listed by .BR ls . .TP \f3delete\f1 [\f2arg\f1] The current directory or specified file or directory within the current directory is deselected for extraction. If a directory is specified, then it and all its descendents are deselected. The most expedient way to extract most of the files from a directory is to select the directory and then deselect those files that are not needed. .TP \f3extract\f1 Ends the interactive dialogue, and causes all selected subtrees to be restored. .TP \f3quit\f1 .I xfsrestore ends the interactive dialogue and immediately exits, even if there are files or subtrees selected for extraction. .TP \f3help\f1 List a summary of the available commands. .RE .TP 5 .B \-m Use the minimal tape protocol. This option cannot be used without specifying a blocksize to be used (see .B \-b option above). .TP 5 \f3\-n\f1 \f2file\f1 Allows .I xfsrestore to restore only files newer than \f2file\f1. The modification time of \f2file\f1 (i.e., as displayed with the \f3ls \-l\f1 command) is compared to the inode modification time of each file on the source media (i.e., as displayed with the \f3ls \-lc\f1 command). A file is restored from media only if its inode modification time is greater than or equal to the modification time of \f2file\f1. .TP 5 \f3\-o\f1 Restore file and directory owner/group even if not root. When run with an effective user id of root, .I xfsrestore restores owner and group of each file and directory. When run with any other effective user id it does not, unless this option is specified. .TP 5 \f3\-p\f1 \f2interval\f1 Causes progress reports to be printed at intervals of \f2interval\f1 seconds. The interval value is approximate, \f2xfsrestore\f1 will delay progress reports to avoid undue processing overhead. .TP 5 \f3\-q\f1 Source tape drive is a QIC tape. QIC tapes only use a 512 byte blocksize, for which \f2xfsrestore\f1 must make special allowances. .TP 5 \f3\-r\f1 Selects the cumulative mode of operation. The .B \-a and .I destination options must be the same for each invocation. .TP 5 \f3\-s\f1 \f2subtree\f1 Specifies a subtree to restore. Any number of .B \-s options are allowed. The restore is constrained to the union of all subtrees specified. Each subtree is specified as a pathname relative to the restore \f2dest\f1. If a directory is specified, the directory and all files beneath that directory are restored. .TP 5 .B \-t Displays the contents of the dump, but does not create or modify any files or directories. It may be desirable to set the verbosity level to \f3silent\f1 when using this option. .TP 5 \f3\-v\f1 \f2verbosity\f1 .\" set inter-paragraph distance to 0 .PD 0 .TP 5 \f3\-v\f1 \f2subsys\f1=\f2verbosity\f1[,\f2subsys\f1=\f2verbosity\f1,...] .PD Specifies the level of detail used for messages displayed during the course of the restore. The \f2verbosity\f1 argument can be passed as either a string or an integer. If passed as a string the following values may be used: \f3silent\f1, \f3verbose\f1, \f3trace\f1, \f3debug\f1, or \f3nitty\f1. If passed as an integer, values from 0\-5 may be used. The values 0\-4 correspond to the strings already listed. The value 5 can be used to produce even more verbose debug output. The first form of this option activates message logging across all restore subsystems. The second form allows the message logging level to be controlled on a per-subsystem basis. The two forms can be combined (see the example below). The argument \f2subsys\f1 can take one of the following values: \f3general\f1, \f3proc\f1, \f3drive\f1, \f3media\f1, \f3inventory\f1, and \f3tree\f1. .ne 2 For example, to restore the root filesystem with tracing activated for all subsystems: .EX # xfsrestore \-v trace \-f /dev/tape / .EE .ne 2 To enable debug-level tracing for drive and media operations: .EX # xfsrestore \-v drive=debug,media=debug \-f /dev/tape / .EE .ne 2 To enable tracing for all subsystems, and debug level tracing for drive operations only: .EX # xfsrestore \-v trace,drive=debug \-f /dev/tape / .EE .TP 5 .B \-A Do not restore extended file attributes. When restoring a filesystem managed within a DMF environment this option should not be used. DMF stores file migration status within extended attributes associated with each file. If these attributes are not preserved when the filesystem is restored, files that had been in migrated state will not be recallable by DMF. Note that dumping of extended file attributes is also optional. .TP 5 .B \-B Change the ownership and permissions of the destination directory to match those of the root directory of the dump. .TP 5 .B \-D Restore DMAPI (Data Management Application Programming Interface) event settings. If the restored filesystem will be managed within the same DMF environment as the original dump it is essential that the \-D option be used. Otherwise it is not usually desirable to restore these settings. .TP 5 .B \-E Prevents .I xfsrestore from overwriting newer versions of files. The inode modification time of the on-media file is compared to the inode modification time of corresponding file in the \f2dest\f1 directory. The file is restored only if the on-media version is newer than the version in the \f2dest\f1 directory. The inode modification time of a file can be displayed with the \f3ls \-lc\f1 command. .TP 5 .B \-F Inhibit interactive operator prompts. This option inhibits .I xfsrestore from prompting the operator for verification of the selected dump as the restore target and from prompting for any media change. .TP 5 .B \-I Causes the \f2xfsdump\f1 inventory to be displayed (no restore is performed). Each time \f2xfsdump\f1 is used, an online inventory in \f2/var/lib/xfsdump/inventory\f1 is updated. This is used to determine the base for incremental dumps. It is also useful for manually identifying a dump session to be restored (see the .B \-L and .B \-S options). Suboptions to filter the inventory display are described later. .TP 5 .B \-J Inhibits inventory update when on-media session inventory encountered during restore. .I xfsrestore opportunistically updates the online inventory when it encounters an on-media session inventory, but only if run with an effective user id of root and only if this option is not given. .TP 5 .B \-K Force .I xfsrestore to use dump format 2 generation numbers. Normally the need for this is determined automatically, but this option is required on the first .I xfsrestore invocation in the rare case that a cumulative restore begins with a format 3 (or newer) dump and will be followed by a format 2 dump. .TP 5 \f3\-L\f1 \f2session_label\f1 Specifies the label of the dump session to be restored. The source media is searched for this label. It is any arbitrary string up to 255 characters long. The label of the desired dump session can be copied from the inventory display produced by the .B \-I option. .TP 5 \f3\-O\f1 \f2options_file\f1 Insert the options contained in \f2options_file\f1 into the beginning of the command line. The options are specified just as they would appear if typed into the command line. In addition, newline characters (\\n) can be used as whitespace. The options are placed before all options actually given on the command line, just after the command name. Only one \f3\-O\f1 option can be used. Recursive use is ignored. The destination directory cannot be specified in \f2options_file\f1. .TP 5 .B \-Q Force completion of an interrupted restore session. This option is required to work around one specific pathological scenario. When restoring a dump session which was interrupted due to an EOM condition and no online session inventory is available, .I xfsrestore cannot know when the restore of that dump session is complete. The operator is forced to interrupt the restore session. In that case, if the operator tries to subsequently apply a resumed dump (using the \f3\-r\f1 option), .I xfsrestore refuses to do so. The operator must tell .I xfsrestore to consider the base restore complete by using this option when applying the resumed dump. .TP 5 .B \-R Resume a previously interrupted restore. .I xfsrestore can be interrupted at any time by pressing the terminal interrupt character (see \f2stty\f1(1)). Use this option to resume the restore. The .B \-a and .I destination options must be the same. .TP 5 \f3\-S\f1 \f2session_id\f1 Specifies the session UUID of the dump session to be restored. The source media is searched for this UUID. The UUID of the desired dump session can be copied from the inventory display produced by the .B \-I option. .TP 5 .B \-T Inhibits interactive dialogue timeouts. .I xfsrestore prompts the operator for media changes. This dialogue normally times out if no response is supplied. This option prevents the timeout. .TP 5 \f3\-X\f1 \f2subtree\f1 Specifies a subtree to exclude. This is the converse of the .B \-s option. Any number of .B \-X options are allowed. Each subtree is specified as a pathname relative to the restore \f2dest\f1. If a directory is specified, the directory and all files beneath that directory are excluded. .TP 5 \f3\-Y\f1 \f2io_ring_length\f1 Specify I/O buffer ring length. .I xfsrestore uses a ring of input buffers to achieve maximum throughput when restoring from tape drives. The default ring length is 3. However, this is not currently enabled on Linux yet, making this option benign. .TP 5 .B \- A lone .B \- causes the standard input to be read as the source of the dump to be restored. Standard input can be a pipe from another utility (such as \f2xfsdump\f1(8)) or a redirected file. This option cannot be used with the .B \-f option. The .B \- must follow all other options, and precede the \f2dest\f1 specification. .P The dumped filesystem is restored into the \f2dest\f1 directory. There is no default; the \f2dest\f1 must be specified. .SH NOTES .SS Cumulative Restoration A base (level 0) dump and an ordered set of delta dumps can be sequentially restored, each on top of the previous, to reproduce the contents of the original filesystem at the time the last delta was produced. The operator invokes .I xfsrestore once for each dump. The .B \-r option must be specified. The \f2dest\f1 directory must be the same for all invocations. Each invocation leaves a directory named .I xfsrestorehousekeeping in the \f2dest\f1 directory (however, see the .B \-a option above). This directory contains the state information that must be communicated between invocations. The operator must remove this directory after the last delta has been applied. .P .I xfsrestore also generates a directory named .I orphanage in the \f2dest\f1 directory. .I xfsrestore removes this directory after completing a simple restore. However, if .I orphanage is not empty, it is not removed. This can happen if files present on the dump media are not referenced by any of the restored directories. The .I orphanage has an entry for each such file. The entry name is the file's original inode number, a ".", and the file's generation count modulo 4096 (only the lower 12 bits of the generation count are used). .P .I xfsrestore does not remove the .I orphanage after cumulative restores. Like the .I xfsrestorehousekeeping directory, the operator must remove it after applying all delta dumps. .SS Media Management A dump consists of one or more media files contained on one or more media objects. A media file contains all or a portion of the filesystem dump. Large filesystems are broken up into multiple media files to minimize the impact of media dropouts, and to accommodate media object boundaries (end-of-media). .P A media object is any storage medium: a tape cartridge, a remote tape device (see \f2rmt\f1(8)), a regular file, or the standard input (currently other removable media drives are not supported). Tape cartridges can contain multiple media files, which are typically separated by (in tape parlance) file marks. If a dump spans multiple media objects, the restore must begin with the media object containing the first media file dumped. The operator is prompted when the next media object is needed. .P Media objects can contain more than one dump. The operator can select the desired dump by specifying the dump label .RB ( \-L option), or by specifying the dump UUID .RB ( \-S option). If neither is specified, \f2xfsrestore\f1 scans the entire media object, prompting the operator as each dump session is encountered. .P The inventory display .RB ( \-I option) is useful for identifying the media objects required. It is also useful for identifying a dump session. The session UUID can be copied from the inventory display to the \f3\-S\f1 option argument to unambiguously identify a dump session to be restored. .P Dumps placed in regular files or the standard output do not span multiple media objects, nor do they contain multiple dumps. .SS Inventory Each dump session updates an inventory database in \f2/var/lib/xfsdump/inventory\f1. This database can be displayed by invoking .I xfsrestore with the .B \-I option. The display uses tabbed indentation to present the inventory hierarchically. The first level is filesystem. The second level is session. The third level is media stream (currently only one stream is supported). The fourth level lists the media files sequentially composing the stream. .P The following suboptions are available to filter the display. .TP 5 \f3\-I depth=\f1\f2n\f1 (where .I n is 1, 2, or 3) limits the hierarchical depth of the display. When .I n is 1, only the filesystem information from the inventory is displayed. When .I n is 2, only filesystem and session information are displayed. When .I n is 3, only filesystem, session and stream information are displayed. .TP 5 \f3\-I level=\f1\f2n\f1 (where .I n is the dump level) limits the display to dumps of that particular dump level. .P The display may be restricted to media files contained in a specific media object. .TP 5 \f3\-I mobjid=\f1\f2value\f1 (where .I value is a media ID) specifies the media object by its media ID. .TP 5 \f3\-I mobjlabel=\f1\f2value\f1 (where .I value is a media label) specifies the media object by its media label. .P Similarly, the display can be restricted to a specific filesystem. .TP 5 \f3\-I mnt=\f1\f2mount_point\f1 (that is, [hostname:]pathname), identifies the filesystem by mountpoint. Specifying the hostname is optional, but may be useful in a clustered environment where more than one host can be responsible for dumping a filesystem. .TP 5 \f3\-I fsid=\f1\f2filesystem_id\f1 identifies the filesystem by filesystem ID. .TP 5 \f3\-I dev=\f1\f2device_pathname\f1 (that is, [hostname:]device_pathname) identifies the filesystem by device. As with the .B mnt filter, specifying the hostname is optional. .P More than one of these suboptions, separated by commas, may be specified at the same time to limit the display of the inventory to those dumps of interest. However, at most four suboptions can be specified at once: one to constrain the display hierarchy depth, one to constrain the dump level, one to constrain the media object, and one to constrain the filesystem. .P For example, .B \-I depth=1,mobjlabel="tape 1",mnt=host1:/test_mnt would display only the filesystem information (depth=1) for those filesystems that were mounted on \f2host1:/test_mnt\f1 at the time of the dump, and only those filesystems dumped to the media object labeled "tape 1". .P Dump records may be removed (pruned) from the inventory using the .I xfsinvutil program. .P An additional media file is placed at the end of each dump stream. This media file contains the inventory information for the current dump session. If the online inventory files in .I /var/lib/xfsdump/inventory are missing information for the current dump session, then the inventory information in the media file is automatically added to the files in .I /var/lib/xfsdump/inventory. If you wish to incorporate the inventory information from the media file without restoring any data, you may do so using the .B \-t option: .EX # xfsrestore \-t \-f /dev/tape .EE This is useful to rebuild the inventory database if it is ever lost or corrupted. The only caveat is that .I xfsrestore needs to read through the entire dump in order to reach the inventory media file. This could become time consuming for dump sessions with large media files. .SS Media Errors \f2xfsdump\f1 is tolerant of media errors, but cannot do error correction. If a media error occurs in the body of a media file, the filesystem file represented at that point is lost. The bad portion of the media is skipped, and the restoration resumes at the next filesystem file after the bad portion of the media. .P If a media error occurs in the beginning of the media file, the entire media file is lost. For this reason, large dumps are broken into a number of reasonably sized media files. The restore resumes with the next media file. .SS Quotas When .I xfsdump dumps a filesystem with user quotas, it creates a file in the root of the dump called .IR xfsdump_quotas . .I xfsrestore can restore this file like any other file included in the dump. This file can be processed by the restore command of .IR xfs_quota (8) to reactivate the quotas. However, the .I xfsdump_quotas file contains information which may first require modification; specifically the filesystem name and the user ids. If you are restoring the quotas for the same users on the same filesystem from which the dump was taken, then no modification will be necessary. However, if you are restoring the dump to a different filesystem, you will need to: .HP - ensure the new filesystem is mounted with the quota option .HP - modify the .I xfsdump_quotas file to contain the new filesystem name .HP - ensure the uids in the .I xfsdump_quotas file are correct .P Once the quota information has been verified, the restore command of .I xfs_quota (8) can be used to apply the quota limits to the filesystem. .P Group and project quotas are handled in a similar fashion and will be restored in files called .IR xfsdump_quotas_group and .IR xfsdump_quotas_proj , respectively. .SH EXAMPLES To restore the root filesystem from a locally mounted tape: .EX # xfsrestore \-f /dev/tape / .EE To restore from a remote tape, specifying the dump session id: .EX # xfsrestore \-L session_1 \-f otherhost:/dev/tape /new .EE To restore the contents a of a dump to another subdirectory: .EX # xfsrestore \-f /dev/tape /newdir .EE To copy the contents of a filesystem to another directory (see \f2xfsdump\f1(8)): .EX # xfsdump \-J \- / | xfsrestore \-J \- /new .EE .SH FILES .TP 25 /var/lib/xfsdump/inventory dump inventory database .SH SEE ALSO rmt(8), xfsdump(8), xfsinvutil(8), xfs_quota(8), attr_set(2). .SH DIAGNOSTICS The exit code is 0 on normal completion, and non-zero if an error occurred or the restore was terminated by the operator. .P For all verbosity levels greater than 0 (\f3silent\f1) the final line of the output shows the exit status of the restore. It is of the form: .EX xfsdump: Restore Status: \f2code\f1 .EE Where \f2code\f1 takes one of the following values: \f3SUCCESS\f1 (normal completion), \f3INTERRUPT\f1 (interrupted), \f3QUIT\f1 (media no longer usable), \f3INCOMPLETE\f1 (restore incomplete), \f3FAULT\f1 (software error), and \f3ERROR\f1 (resource error). Every attempt will be made to keep both the syntax and the semantics of this log message unchanged in future versions of xfsrestore. However, it may be necessary to refine or expand the set of exit codes, or their interpretation at some point in the future. .SH BUGS Pathnames of restored non-directory files (relative to the \f2dest\f1 directory) must be 1023 characters (MAXPATHLEN) or less. Longer pathnames are discarded and a warning message displayed. .P There is no verify option to \f2xfsrestore\f1. This would allow the operator to compare a filesystem dump to an existing filesystem, without actually doing a restore. .P The interactive commands (\f3\-i\f1 option) do not understand regular expressions. .P When the minimal rmt option is specified, \f2xfsrestore\f1 applies it to all remote tape sources. The same blocksize (specified by the .B \-b option) is used for all these remote drives. .P .I xfsrestore uses the alert program only when a media change is required. .P Cumulative mode (\f3\-r\f1 option) requires that the operator invoke .I xfsrestore for the base and for each delta to be applied in sequence to the base. It would be better to allow the operator to identify the last delta in the sequence of interest, and let .I xfsrestore work backwards from that delta to identify and apply the preceding deltas and base dump, all in one invocation. xfsdump-3.1.6+nmu1/man/Makefile0000644000000000000000000000054712607344125013176 0ustar # # Copyright (c) 2000-2001 Silicon Graphics, Inc.

Writes * may be cut short due to media events (e.g., EOM). The mark * mechanism allows the caller to determine what portion of the write data * stream is guaranteed to have been committed to media. * * Marks may be placed in the stream during writes. During subsequent * reads of the data stream, the media object may be positioned at a * specific mark, or to the next mark in the stream. * * To accomodate end-of-media uncertainty, the marks are set in two steps. * First the caller asks to set a mark at a position within the write stream, * providing a callback function. The callback will be invoked when the data * prior to that mark has been committed to media. * * The caller must re-position the media (e.g., change media objects or * begin a new media file) and re-write any portion of the data written * after the last committed mark. It is entirely possible for part of that * data to have made it onto the previous media file, due to the uncertainty * of end-of-media handling of some drives. Thus the caller must be prepared * for portions of data read from the end of one media file to be duplicated * at the beginning of the next media file. * * To allow repositioning the stream in the above scenarios, * drive_t supplies forward-space-file, backward-space-file, rewind, * seek_mark, and get_mark operators. * * A call to the end_read or end_write operator virtually positions the * media at the beginning of the next media file. Thus if a caller calls * begin read, looks at the header and decides to overwrite the media * file, a call to the bsf operator must be made prior to the call to * begin_write. However, if the media is positioned at EOD and the caller calls * begin_read, EOD will be returned and no repositioning is needed. A call * to begin_write will append a new media file after the last media file. * * Drive_init1 selects and instantiates a drive manager for each drive * identified on the command line. This is done by showing the drive * successively to each drive strategy module. The drive strategies * supply a match score. The strategy with the highest score gets to * instantiate a drive manager for that drive. * * Drive_init2 allocates and initializes read and write header buffers for * each drive, and calls each drive manager's init operator, which begins async * initialization of the drive. This includes determining if a media object * is currently mounted in that drive. * * Drive_init3 synchronizes with the async initializations kicked off by * drive_init2. * * Each drive strategy is defined by a drive_strategy_t. This supplies * a match function, and an instantiate function. * * The match function lets the given strategy determine if it is the correct * strategy to choose. The instantiate function creates a driver manager. * * The I/O write model presents the user with a function to get a write buffer, * or get a page-aligned write buffer, and a function to take back the buffer * and commit part or all of that buffer to media. The read model is similar; * the caller may ask for a buffer filled with read data, and gives the buffer * back after the data is used. These models facilitate high-performance * operation, since the buffers can be used in direct I/O. */ /* drive_hdr_t - drive media file header * * A drive media file header is imbedded in the global media file header * structure, which is in turn placed at the beginning of each media file. The * drive hdr has three parts: generally useful drive-related info, info * specific to the selected drive strategy, and upper layer info.

The client and slave can each hold at most one message at a * time. all others must be on one of the two queues. the messages must * circulate in that order: ready, client, active, slave, ready, ... * initially all messages are on the ready queue, with status set to * INIT. The client uses ring_get to remove a message from the ready queue. * the client can then use the message to read or write. to read, the client * sets the op field to READ, and places the message on the active queue. the * slave will remove messages from the active queue, invoke the client-supplied * read function with the message's buffer, record the read function's return * value in the message, set the message status to OK (read function returned 0) * or ERROR (read returned non-zero), and place the message on the ready queue. * the client will see the message after removing all messages ahead of it on * the ready queue. to write, the client follows almost the same procedure, * except the client fills the buffer and sets the op to WRITE prior to placing * the message on the active queue. * * if the client-supplied read or write function returns an error, the slave * will set the message status to ERROR. the slave will pass all subsequent * messages appearing on the active queue directly to the ready queue with * no I/O done and the message status set to IGNORE. the slave will remain * in this state until a reset is performed (see below). * * The client may at anytime place a NOP msg on the ring. the slave does * nothing with this mmessage other than to place it back on the ready queue * with NOPACK status. This is useful for inhibiting read-ahead. * * To flush the ring, the client must repetatively place TRACE messages on the * active queue until it sees an IGNORE msg on the ready queue. the slave will * simply transfer TRACErs from active to ready with no other action taken * (other than to set the message status to IGNORE). * * the client may at any time reset the ring. the reset will return to the * client when the current I/O being executed by the slave completes, and * all messages have been wiped clean and placed on the ready queue with * status set to INIT. the ring_reset function accomplishes this internally by * placing a RESET message on the active QUEUE, and continuing to remove * messages from the ready queue (without placing them on the active queue) * until the RESET message is seen the slave responds to a reset message by * setting the status to RESETACK, queueing the message on the ready queue, and * waiting for a message from the active queue. ring_reset will then re- * initialize the ring and return. note that the client may be holding one * message at the time the reset is called. if so, it must pass a pointer to * that message into the reset call. otherwise it must pass in NULL. * * the ring_destroy function may be invoked to shut down the ring and kill the * slave thread. it simply places a DIE message on the active queue, and waits * for a DIEACK response. it then de-allocates all semaphores memory allocated * by ring_create. * * the message structure includes a 64 bit field for the convenience * of the client. it is not perturbed during any ring operations. * * the ring maintains four performance metering values: the number of times * the slave and client attempted to get a message, and the number of times * those attempts resulting in blocking. */ /* ring_msg - structure of messages managed by ring */ enum ring_op { RING_OP_NONE, RING_OP_READ, RING_OP_WRITE, RING_OP_NOP, RING_OP_TRACE, RING_OP_RESET, RING_OP_DIE }; typedef enum ring_op ring_op_t; enum ring_stat { RING_STAT_INIT, RING_STAT_OK, RING_STAT_ERROR, RING_STAT_NOPACK, RING_STAT_IGNORE, RING_STAT_RESETACK, RING_STAT_DIEACK }; typedef enum ring_stat ring_stat_t; enum ring_loc { RING_LOC_READY, RING_LOC_ACTIVE, RING_LOC_CLIENT, RING_LOC_SLAVE }; typedef enum ring_loc ring_loc_t; struct ring_msg { ring_op_t rm_op; ring_stat_t rm_stat; int rm_rval; off64_t rm_user; char *rm_bufp; /* ALL BELOW PRIVATE!!!

It uses XFS-specific directives for optimizing the dump of an XFS filesystem, and also knows how to backup XFS extended attributes. Backups created with xfsdump are "endian safe" and can thus be transfered between Linux machines of different architectures and also between IRIX machines. . xfsrestore performs the inverse function of xfsdump; it can restore a full backup of a filesystem. Subsequent incremental backups can then be layered on top of the full backup. Single files and directory subtrees may be restored from full or partial backups. xfsdump-3.1.6+nmu1/debian/xfsdump.postrm0000644000000000000000000000025712643556443015147 0ustar #!/bin/sh set -e if [ "$1" = 'remove' ]; then for file in xfsdump xfsrestore; do if [ -L /usr/sbin/$file ]; then rm /usr/sbin/$file fi done fi #DEBHELPER# xfsdump-3.1.6+nmu1/debian/shlibs.local0000644000000000000000000000010012607344125014466 0ustar libattr 1 libattr1 (>= 2.0.0) libhandle 1 xfsprogs (>= 2.6.30) xfsdump-3.1.6+nmu1/configure.ac0000644000000000000000000000374512620476160013254 0ustar AC_INIT([xfsdump], [3.1.6]) AC_PREREQ(2.50) AC_CONFIG_AUX_DIR([.]) AC_CONFIG_MACRO_DIR([m4]) AC_CONFIG_SRCDIR([common/main.c]) AC_CONFIG_HEADER(include/config.h) AC_PREFIX_DEFAULT(/usr) AC_PROG_LIBTOOL AC_ARG_ENABLE(shared, [ --enable-shared=[yes/no] Enable use of shared libraries [default=yes]],, enable_shared=yes) AC_SUBST(enable_shared) AC_ARG_ENABLE(gettext, [ --enable-gettext=[yes/no] Enable alternate language support [default=yes]],, enable_gettext=yes) AC_SUBST(enable_gettext) AC_ARG_ENABLE(lib64, [ --enable-lib64=[yes/no] Enable lib64 support [default=yes]],, enable_lib64=yes) AC_SUBST(enable_lib64) # # If the user specified a libdir ending in lib64 do not append another # 64 to the library names. # base_libdir=`basename "$libdir"` case $base_libdir in lib64) enable_lib64=no esac # # Some important tools should be installed into the root partitions. # # Check whether exec_prefix=/usr: and install them to /sbin in that # case.
