I’ve already written about my PDU suddenly dying — and in that post I explained that I was going to do some changes to the homelab power layout. It’s time to do those changes 🙂

It’s time for another ZFS pool expansion. When I last expanded; I doubled the capacity of my 2nd vdev — going from 16 TB to 32 TB raw capacity. This time I’m doubling again — replacing the last limiting drive, and fully utilizing the all the 8 TB drives 😃

I’ve been planning to enable scheduled S.M.A.R.T. scans ever since I built my file server, but it was just one of those things that I never got around to do.

Well — when one of the 8 TB drives suddenly started reporting S.M.A.R.T. errors, the scheduled scans got back on the agenda. So let’s do that now 👇

I have a local mail server with Postfix and Dovecot — I use it as a local SMTP smart host, and “notification center”.

While gathering information for this post; I discovered that my file server have been sending me emails, warning me of S.M.A.R.T. errors on a disk in the ZFS pool. Every day — since September!

So I’ve included a section on how to avoid missing important server emails.

My homelab PDU suddenly died! It’s dead, D-E-D, dead! There are few things worse than a server rack suddenly going completely silent…

The PDU has had an error since the power outage last summer — F11 means Power fail on auxiliary 1. Which is an odd error for a PDU with only one input. And; it wasn’t possible to clear or reset it it 😕
