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.

Since we first moved into this house — I’ve wanted to ceiling mount a Wi-Fi access point on the 2nd floor. But getting a network cable to the attic was challenging, so instead I opted for a Unifi UAP-AC-IW in the upstairs living room.

It’s time to do it right, but I’m not running just one. My earlier Wi-Fi mapping revealed poor 5 GHz coverage in the kid’s rooms, so I’m running two CAT6 cables — for two ceiling mounted Wi-Fi access points.

To have the option of running more CAT6 to rooms on the 2nd floor later — I’m including a 10 Gbit fiber as well 😎

And as my previous runs — no visible cables.
