Hello.
My setup is:
The Proxmox PC keeps all its CTs and 1 VM on the TrueNAS using iSCSI.
The idea behind my setup was that it felt nice that the TrueNAS would handle all the storage heavy lifting - ZFS, RAID etc., while the Proxmox mini PC would be a “compute-only” node that has a naked Proxmox install with some config.
The problem with that is if the TrueNAS machine loses power or is restarted, the Proxmox CTs/VMs switch their filesystem to read-only and stop responding to requests. This is because the iSCSI connection is interrupted. When the TrueNAS is back online, Proxmox doesn’t make any attempt to restart the VMs/CTs - they’d still be broken.
It’s annoying to me to have to VPN to the Proxmox web ui and wait 15 minutes until all the CTs/VMs are restarted and now again functioning on the “alive” iSCSI connection.
I was wondering what are my options here to remove the dependency chain?
I’m really into the idea of decomissioning the Proxmox node because I’m scared I won’t be able to (over VPN) change the power state of the machine if something goes wrong, since it only has vPro and not iSCSI like the TrueNAS machine. By doing that, I’d consolidate the storage and the compute into the TrueNAS machine.
Options I can think of:
EDIT: I didn’t make it clear at first - TrueNAS stores more data than just VMs - documents, Linux ISOs ™, photos, Syncthing

It’d be nice to have Proxmox and TrueNAS side by side on one machine, but since TrueNAS forums are against the virtualization of TrueNAS (yes I know people do that, but I’m not willing) I’m somewhat stuck with having to have one bare metal machine per appliance.
I’m sure you’ve heard plenty through the forums, but Truenas virtualized is perfectly fine so long as you’re passing through an HBA directly. It doesn’t affect reliability any, but it doesn’t add any features either.
“Can I virtualized Truenas” is probably the second most popular question after “do I really need ECC ram”
I took my truenas some months ago and installed proxmox on that server instead.
I can’t from your post figure out what you need truenas for? Proxmox runs zfs, etc?
I made an lxc container with samba to share the discs in proxmox.
I edited my post to clarify. TrueNAS also keeps documents, photos, torrents, music. I also use the mount feature so that the music server LXC can access music
