fsck.xfs
is called by the generic Linux
fsck(8)
program at startup to check and repair an XFS filesystem.
XFS is a journaling filesystem and performs recovery at
mount(8)
time if necessary, so
fsck.xfs
simply exits with a zero exit status.
If you wish to check the consistency of an XFS filesystem,
or repair a damaged or corrupt XFS filesystem,
see
xfs_check(8)
and
xfs_repair(8).
