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.
