fsck.xfs [ filesys ... ]
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_repair(8).
However, the system administrator can force fsck.xfs to run xfs_repair(8) at boot time by creating a /forcefsck file or booting the system with "fsck.mode=force" on the kernel command line.
