Services the only supported sqlite databases struggled (Jellyfin). Anything that worked with postgresql worked like a charm. So trick on the sqlite ones is a local PV then do a task to copy to NFS periodically.

My setup was a central NAS hosting an NFS server then each Pi mounted PVs from the NFS CSI driver over the network and I only used local storage to boot the OS.

I manually manage the media files but I do assign the categories, I just mount it on Jellyfin as read only so it can’t make any changes and it stores the metadata and album art on the Jellyfin system partition.

Raspberry Pi 4 4GB handled it just fine for me the last couple years.

Figure out why my new 10GbE NIC won’t read in my repurposed gaming rig (now server), get all my storage migrated over to Ceph, transition my services over to Proxmox hosted Talos k8s stack from my RPi-hosted k3s stack.

A relatively newish SBC can run Jellyfin and even do some light transcoding (single stream full HD or 2-3 streams SD).

I love Jellyfin (kind of love/hate haha), but I would never trust it to manage my media files themselves.

Definitely check out k3s. I ran a 7 node arm64 cluster for a couple years and it served me well. I’ve since graduated to proxmox/ceph and all that, wish me luck 😅
