Once a month is fine ("/etc/cron.monthly/zfs-scrub"):
#!/bin/bash
#
# ZFS scrub script for monthly maintenance
# Place in /etc/cron.monthly/zfs-scrub
POOL="storage"
TAG="zfs-scrub"
# Log start
logger -t "$TAG" -p user.notice "Starting ZFS scrub on pool: $POOL"
# Run the scrub
if /sbin/zpool scrub "$POOL"; then
logger -t "$TAG" -p user.notice "ZFS scrub initiated successfully on pool: $POOL"
else
logger -t "$TAG" -p user.err "Failed to start ZFS scrub on pool: $POOL"
exit 1
fi
exit 0
Didn't know about the logger script, looks nice. Can it wrap the launch of the scrub itself so that it logs like logger too, or do you separately track its stdout/stderr when something happens?
update: figured how you can improve that call to add logs to logger
Scrub doesn't log anything by default, you run it and it returns quickly... you have to get the results out of zpool status or through zed.
That script might do with the "-w" parameter passed to scrub. Then "zpool scrub" won't return until the scrub is finished.
