[OpenIndiana-discuss] Monitor RAIDZ disk failure

[Richard L. Hamilton]

I would think that

fmadm faulty

would show that (and various other problems, too), or nothing if there was nothing wrong.

Or something like

zpool list|nawk 'BEGIN {bad=0} NR==1 {header=$0} NR>1 {if ($7!="ONLINE") {bad++;saved[bad]=$0}} END {if (bad>0) {print header;for (x in saved) print saved[x]}}'

should produce output (including the header) only if there are lines after the header where the 7th field is not "ONLINE".

Use sudo or RBAC if you choose the fmadm faulty command (because it needs privileges), and do that from a cron job; that will generate email (you do have your email set up correctly, right? :-) ) only if it generates output.

That's the easiest, probably. If you already have Xymon set up (or are willing to set it up, which requires some work for a server plus setup on each client), see https://wiki.xymonton.org/doku.php/monitors:bb-zfs

You were expecting maybe that the system would magically know who you are and send a telepathic message or at least a text message? :-) Good luck with that.
