Disks not migrated and can't start

[dignus]

Hi,

I had a server in our proxmox cluster that gave some weird warnings. I decided to reboot it. It had 3 VM's on it. While rebooting it, proxmox decided it was going to live on another host in the cluster. But... it had about 1 TB of local LVM storage on the rebooted server.

So .. the old host comes back online, but proxmox is telling me the VM is living on another machine. It cannot possible have transferred the data, I can see the LV's on the old host. But I can't migrate the VM back to where it's data lives.

Is there a way to forcefully tell proxmox that vm X lives on host Y without the migration process?

Does the VM on the new host show an entry for the old LVM disk that's only on the original node?

Also for the LVM storage do you have the shared box ticked?

No, shared box was not ticket.
The new host doesn't see the logical volumes.

Your need to power off the VM if it's started on new host.

Copy the VM config file back to the old host and manually add the correct config file lines to add back the LVM's.

The config files are held at : /etc/pve/qemu-server/< VMID>.conf
Your need to use another VM's config file to view the correct format / layout for the LVM config line.

Got it, thx.
