Pool OFFLINE after reverting backup

[n008]

I have a Proxmox Server in which I run TrueNAS. I had to revert my TrueNAS from a ProxMox backup after some catastrophic failures within TrueNAS.

However, after restoring from my ProxMox backup, my Pool status is OFFLINE and not able to be imported:
Pools: freeRAID (System Dataset Pool) OFFLINE

Code:

root@freenas[~]# zpool status
  pool: freenas-boot
 state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
        still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
        the pool may no longer be accessible by software that does not support
        the features. See zpool-features(5) for details.

All my hard drives are still showing available in proxmox:

I guess the first question is, what exactly were you doing for PCIe passthru of the pool disks. This is currently rated as "experimental" by the Proxmox folks and has been known to fail in dramatic ways. Without a lot of detail about your system, I'm tempted to say that you designed a system that was not serviceable.

Can you please describe both your physical virtualization platform (significant detail is better) and also your virtual machine template that you are running TrueNAS inside, especially including what is being done for PCIe passthru and how well the virtualized TrueNAS fared during its burn-in?

How do I delete post? Found out that this was a Proxmox issue that comments out drives for passthrough on restore for some reason:

Restore form backup issue

Hi, I have Proxmox 7.2.3 I use the built-in back for my VMs. But there is an issue when restoring. For any VM that I have hardware passthrough enabled the restore is commented out and other characters are added to that line in the conf file. So after a restore I have to login the Proxmox and...

Sorry for bothering!
