VM Boot lvmid issue. Grub rescue

[Hartmut Proeger]

Hello,
I want to move several VMs from a Proxmox 5.4-15 server to a Proxmox 6.3-3 server.
Procedure :
- VM stopped
- created a backup of VM
- copied backup to Proxmox 6.3-3 server to /var/lib/vz/dump
- created the VM on the new Proxmox 6.3-3 serverxmox 6.3-3 server with qmrestore
- When trying to start the VM, the console displays:
error: disk 'lvmid/h7PJQA-GR59....' not found.
Entering rescue mode...
grub rescue>

Does anyone have any idea how to fix this error?

Best Regards

Can you post your VM config ('qm config <vmid>' or '/etc/pve/qemu-server/<vmid>.conf')?

Note that if your VM needs multiple drives to boot, they now all need to be marked 'bootable' (i.e. selected) in the bootorder.

Hello Stefan,

thank you very much, that was the problem. Only one of three disks was set to bootable.
After setting the other two disks to bootable as well, the VM started.
