xfs_scrub_all - scrub all mounted XFS filesystems

xfs_scrub_all [ -hV ]

xfs_scrub_all attempts to read and check all the metadata on all mounted XFS filesystems. The online scrub is performed via the xfs_scrub tool, either by running it directly or by using systemd to start it in a restricted fashion. Mounted filesystems are mapped to physical storage devices so that scrub operations can be run in parallel so long as no two scrubbers access the same device simultaneously.

-V

The exit code returned by xfs_scrub_all is the sum of the following conditions:
0 - No errors

These are the same error codes returned by xfs_scrub.
