@thelemonalex I use native linux nfs server. Manage shares using /etc/exports file.

For SMB, I use vm with samba and mount a few folders over nfs from proxmox (it just gives me a static IP in case if I decide to change something from proxmox side).

I manage zfs on the proxmox host. I think you can’t export zfs dataset to be managed by VM (except drive passthrough).

My infra has 1 proxmox bulky node with 2 HDD (zfs) and 3 nodes with small ssd/nvme in the cluster.

@thelemonalex I usually find that sata cable or connector are bad.

Personally I use proxmox as a host and share bulky nfs mounts for each VM like Immich, Plex/Jellyfin. For gitea and other small VM - use VM virtual drive and back it up periodically

@AdrianTheFrog blocking 25 port is a standard policy.
Buy static IP (subnet actually) or ask support to remove all firewall rules (I had to speak with many of the support personnel until found someone who knows how to do).

Ended up with using a separate VPS for mail server as my att ip was in blacklisted)
