Next time, when you make major changes like ZFS upgrade, create a checkpoint and keep it for a while. You can roll back everything, even the pool version.

I personally like to run ZFS on a bare metal server, just the plain OS, no further “NAS” or virtualization software.

I don’t really know what your use cases are, so I cannot tell if it’s adequate for you.

I tried Photoprism, Ente and Immich.

Immich is by far the best. It has got an app that really does what it should do, has an AI that actually works and is easy to host and to update.
