# Scrub Expired - Check if all volumes have been scrubbed in at least the last

# 8 days. The general guide is to scrub volumes on desktop quality drives once
|
|
||||||
# a week and volumes on enterprise class drives once a month. You can always
|
|
||||||
# use cron to schedule "zpool scrub" in off hours. We scrub our volumes every
|
|
||||||
# Sunday morning for example.
|
|
||||||
#
|
|
||||||
# Scrubbing traverses all the data in the pool once and verifies all blocks can
|
|
||||||
# be read. Scrubbing proceeds as fast as the devices allows, though the
|
|
||||||
# priority of any I/O remains below that of normal calls. This operation might
|
|
||||||
# negatively impact performance, but the file system will remain usable and
|
|
||||||
# responsive while scrubbing occurs. To initiate an explicit scrub, use the
|
|
||||||
# "zpool scrub" command.
|

||||||
#
|
