You won’t be using a traditional RAID with TrueNAS Scale. You have a choice of Stripe, Mirror, RAIDZ1, RAIDZ2, RAIDZ3, dRAID1, dRAID2, dRAID3. The docs are very detailed, so you should read up on RAIDZ and the other types elsewhere, too.

Since you only use Plex because of overseerr: There is a fork called Jellyseer that is compatible with Jellyfin. Haven’t tried it yet but it may be worth looking into.

I love kubernetes. At the start of the year I installed k3s von my VPS and moved over all my services. It was a great learning opportunity that also helped immensely for my job.

It works just as well as my old docker compose setup, and I love how everything is contained in one place in the manifests. I don’t need to log in to the server and issue docker commands anymore (or write scripts / CI stages that do so for me).
