xfs_scrub_all - scrub all mounted XFS filesystems

NAME SYNOPSIS DESCRIPTION OPTIONS EXIT CODE SEE ALSO

NAME

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.

OPTIONS

Supported unit suffixes are y, q, mo, w, d, h, m, and s for years, 90-day quarters, 30-day months, weeks, days, hours, minutes, and seconds, respectively. If no units are specified, the default is seconds.
