Restoring CT's from subvols (ZFS)

[herefortheLAN]

ProxMox 8.0.3

Good Evening:

I messed up. I added a Zpool RAIDZ1 and moved all my containers (via "Move Storage") from the default local-lvm to this new ZFS RAIDZ1. Then I attempted to migrate the root drive to a new drive and borked the install.

So, figuring my CTs were safe on my RAIDZ1 (4 separate SSDs) and reinstalled ProxMox. I was able to to add the RAIDZ1 via

zpool import -f zpool

(zpool is the name of the zpool; original, I know). Obviously, the CTs did not show up but I do have the subvols in the "VMDisks" section of the zpool:



Is there any way to rebuild my containers using the subvols?

Thank you!

You only copied the virtual disks but not the whole LXCs. You also need the config files which were still on the system disk you have wiped.
So you would have to create new config files (in "/etc/pve/lxc" and "/etc/pve/qemu-server") using the same VMIDs based on your memory unless you also got a backup of your /etc/pve folder.

Wanted to thank you. It was as you said. Still you gave me enough and after several hours I have everything back. What was helpful was that I use the VMIDs that match the last octet of the containers ip address. That made matching a bit easier.

The VMs were much more difficult. The key is to backup and use the previous TPM drive. Otherwise you will never get a Windows Server VM to boot, again.
