I am aware of `zfs status`, but I only run it a few times each month.
Is there some kind of automated ZFS pool monitoring tool that notifies
the sysadmin of a failure?
I'd just run this from cron now and then:
#!/bin/sh
export PATH=/bin:/sbin:/usr/bin
host=$(hostname)
admin='you@preferred.mail'
zpool status -x | mailx -s "Zpool status for $host" $admin
exit 0
If you can do without constant "EVERYTHING'S FINE!" messages:
#!/bin/sh
export PATH=/bin:/sbin:/usr/bin
host=$(hostname)
admin='you@preferred.mail'
pat='all pools are healthy'
if zpool status -x | grep "$pat" > /dev/null; then
logger -t 'zpool' "$pat"
else
zpool status -x | mailx -s "Zpool status for $host" $admin
fi
exit 0
