восстановить файловую систему XFS (repair an XFS filesystem)
Ошибки (баги) (Bugs)
The filesystem to be checked and repaired must have been
unmounted cleanly using normal system administration procedures
(the umount(8) command or system shutdown), not as a result of a
crash or system reset. If the filesystem has not been unmounted
cleanly, mount it and unmount it cleanly before running
xfs_repair.
xfs_repair does not do a thorough job on XFS extended attributes.
The structure of the attribute fork will be consistent, but only
the contents of attribute forks that will fit into an inode are
checked. This limitation will be fixed in the future.
The no-modify mode (-n option) is not completely accurate. It
does not catch inconsistencies in the freespace and inode maps,
particularly lost blocks or subtly corrupted maps (trees).
The no-modify mode can generate repeated warnings about the same
problems because it cannot fix the problems as they are
encountered.
If a filesystem fails to be repaired, a metadump image can be
generated with xfs_metadump(8) and be sent to an XFS maintainer
to be analysed and xfs_repair fixed and/or improved.
