I don’t understand all the words you’re using but:

Having had Proxmox sort out my drives and having had failures and Proxmox refuse to start if the drive isn’t present (it was present but forgot it’s label so it wasn’t there for Proxmox) I recommend just passing through the drives to your NAS and having it handle the drives.

That way if they fail then your NAS fails but Proxmox boots.

Also if you’re mounting them directly use the “nofail” option so it doesn’t kill your Proxmox if you don’t just have the NAS handle it.
