Yeah, I come from the same scenario. Consolidated multiple nodes incl. a NAS into one. Initially had the HDD (which run through a controller anyway) passed through to a TrueNAS VM. That was…a mistake. TrueNAS can become a real bitch if it’s own VM storage is slower/has a hiccup while the rest of the pool is not. And a lot of other things are a PIA as well, e.g.permission wise, especially with a FreeIPA Domain. And all that for a quite hefty price in ressources.

The day I pulled the plug on that was a good day. Later had the issue repeat itself with a client system that the client brought with him.

Nowadays I really love the proxmox only solution,even though it’s somewhat icky to run something directoy on the host - but it’s acceptable imho,when it’s literally built onto host data-as it is the case for ZFS NFS anyway.

(I have Samba in a proper LXC, though - but rarely use it these days as we run everything via NFSv4 by now)
