Orphaned VM Recovery After Boot Volume failure


Sep 11, 2019
Hello all,

I am new to proxmox. I set up a test server a few months back with some test VMs for my home lab. Although these weren't data critical quite a bit of work went into configuring and setting them up with the software and pci passthrough, custom GPU boot bios, etc.

A while ago my raid 1 boot volume failed and seemed to copy over the problems to the other node. Since determining the volume is not recoverable, I have reinstalled Proxmox now running v6. I have access to my previous LVM-Thin container and can see the disk volumes for the old VMs. Is there any way I can import these and recover the VM data?

You could try to mount the LVM volume. It should be formatted with ext4.
Are they qcow files?
You can create a new VM and then use qm importdisk ( https://pve.proxmox.com/pve-docs/qm.1.html ) to import them to the VM. If you want you should be able to first detach and then remove the disk initially created fro the VM. After you attach the imported disk you might have to adapt the boot order in the VMs options.
