I almost got it right. When I installed my home server, I was sure to set up mdadm monitoring so it would email me if a drive in my RAID array failed.

I idly checked /proc/mdstat today and saw that my array is degraded. I checked logs and discovered that this happened in July.

Now, mdadm did send mail, though I didn’t receive it. If I had tested outgoing email to that account, I would have noticed a delivery failure from my own blacklisting of dynamic IPs.

Quis custodiet ipsos custodes?

I use xmpp for notifications.

If you do that, you lose notifications because after python upgrade last year, xmppsend stopped working ;)

Had the same thing happen to me. I setup things to use a gmail account to send it next time.

I’m getting three (larger) drives to reconstitute the array, so that I have a hot spare.

I’ll probably fix notifications, too.
