xfs_scrub_all - scrub all mounted XFS filesystems
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.
The exit code returned by xfs_scrub_all is the sum of the following
- Display help.
- Prints the version number and exits.
0 - No errors
4 - File system errors left uncorrected
8 - Operational error
16 - Usage or syntax error
- These are the same error codes returned by xfs_scrub.
