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). FILES ~ /etc/fstab. SEE ALSO ~ fsck(8), fstab(5), xfs(5), xfs_check(8), xfs_repair(8).
