[SOLVED] Error when backupping Template

cromatn5 · Jan 11, 2021

I converted a vm to template and i would like to backup it, to keep a copy on PBS, and had this error.
I can normaly backup all others "standards" vm.

and what kind of storage are you using? could you include the full VM config as well? thanks!

Did a fresh PVE installation. Backup of a VM-template to PBS still doesn't work. The VM-template is on a LVM-Thin-partition. Backup of a LVM container template works fine. If the VM-template is on a ZFS drive, the backup works fine, too.

this is a new, separate issue with read-only EFI disks.. I'll take a closer look!
