xfs_check – check XFS filesystem consistency Synopsis xfs_check [ -i ino ] … [ -b bno ] … [ -f ] [ -s ] [ -v ] [ -l logdev ] device Description xfs_check checks whether an XFS filesystem is consistent. It is normally run only when there is reason to believe that the filesystem…
xfs_bmap – print block mapping for an XFS file Synopsis xfs_bmap [ -adlpv ] [ -n num_extents ] file xfs_bmap -V Description xfs_bmap prints the map of disk blocks used by files in an XFS filesystem. The map lists each extent used by the file, as well as regions in the file that do not…
xfs_admin – change parameters of an XFS filesystem Synopsis xfs_admin [ -eflpu ] [ -c 0|1 ] [ -L label ] [ -U uuid ] device xfs_admin -V Description xfs_admin uses the xfs_db(8) command to modify various parameters of a filesystem. Devices that are mounted cannot be modified. Administrators must unmount filesystems before xfs_admin or…
