NAME

xfs_scrub_all - scrub all mounted XFS filesystems

SYNOPSIS

xfs_scrub_all [ -hxV ]

DESCRIPTION

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

--aut-medi-sca-interval: Automatically enable the file data scan (i.e. the -x flag) if it has not been run in the specified interval. The interval must be a floating point number with an optional unit suffix. Supported unit suffixes are y, q, mo, w, d, h, m, and s for years, 9-day quarters, 3-day months, weeks, days, hours, minutes, and seconds, respectively. If no units are specified, the default is seconds.
--aut-medi-sca-stamp: Path to a file that will record the last time the media scan was run. Defaults to /var/lib/xfsprogs/xfs_scrub_all_media.stamp.
-h: Display help.
-x: Read all file data extents to look for disk errors.
-V: Prints the version number and exits.

EXIT CODE

The exit code returned by xfs_scrub_all is the sum of the following conditions:
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.
