Vanilla Ubuntu 18.04 LTS. Every couple of months or so I update all the packages and reboot. That's really all the maintenance I've ever done on it, apart from initial setup. I ought to set it up so that it can email me if a zfs scrub ever detects a problem, but I haven't done that yet.

Thanks! That's a valuable data point for my comparison.

By the way, do you run software like Nextcloud, or are you just using it as a storage tank?

I use syncthing and Plex, other than that it’s mostly just storage

Ok, thanks again!
