Hello everyone,
I am currently having the problem that I cannot restore a VM (both Linux and Windows) with an EFI partition from a backup.
The storage for the disks is an LVM thin and the backup is stored on a server using NFS.

Once I want to restore the backup from the server, I run into the following error:
Code:

Does anyone have an idea what I can try to do?
Is this a known issue or am I running just into a corner case?

Thank you very much for your help.

Best regards,
Marcel

I found a workaround for this problem.

The trick is to NOT restore the backup on a LVM thin storage.
I just restored the VM on a storage with type disk and moved it over to the LVM thin storage.
This worked for both linux and windows vms.

Hope this helps someone.

Best regards,
Marcel
