scrub volume
Description Analyzes specified volumes to find and fix disk errors. This command acts on the disk portions
spanned by each volume, but it does not act on dedicated spares or leftover disks. This command
will fix parity mismatches for RAID 3, 5, 6, and 50; mirror mismatches for RAID 1 and 10; and
media errors for all RAID levels.
Volume scrub can last over an hour, depending on volume size, utility priority, and amount of I/O
activity. You can use a volume while it is being scrubbed. To check the progress of a volume scrub
job, use the show volumes command.
NOTE: Only one scrub operation can be running on a vdisk at a time. If a manual scrub is started
while a background scrub is in progress, the background scrub will terminate and will start over 24
hours after the manual scrub completes.
When a scrub is complete, event 207 is logged and specifies whether errors were found and
whether user action is required.
