xfs_scrub_all(8) System Manager's Manual xfs_scrub_all(8)
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 re-
stricted 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
--auto-media-scan-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, 90-day
quarters, 30-day months, weeks, days, hours, minutes, and sec-
onds, respectively. If no units are specified, the default is
seconds.
--auto-media-scan-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 con-
ditions:
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.
