[SOLVED] Renaming of VG and LV

[dmox]

Hi,
yesterday I renamed a VG and a corresponding LV. While doing so I did not think about the linked VMs which are having their disks lying on the LV. Now they woun't boot up with the following message:

kvm: -drive file=/dev/vm-storage/vm-111-disk-0,if=none,id=drive-scsi0,cache=writeback,format=raw,aio=threads,detect-zeroes=on: Could not open '/dev/vm-storage/vm-111-disk-0': No such file or directory
TASK ERROR: start failed: (...)

Currently, I associated the renamed LV back to its renamed VG. Next I want to associate the VM-disks to the renamed LV. I tried this with the following command:

qm move_disk 111 scsi0 lv-vm-storage

Unfortunately, this returns me

storage 'lvm-thin-1' does not exists

whereas lvm-thin-1 is the old LV name.

Subsquently, I wonder if I can manipulate the VM configuration files directly under /etc/pve/qemu-server without getting into trouble because some metadata becomes dirty or other undesired things happen when I do this?

​

Thank you for your help.
Kind regards, David

I guess you realise that you should have moved the VM's storage first...I think it works to edit the files in /etc/pve/qemu-server. The VM's are off so it should work, based on me doing it once before only.

Ok, thank you for your answer. It worked.
So the correct way would've been to create a temporary LV first, move the VMs there, rename the old LV, move the VMs to the renamed LV and delete the temporary LV?
