HA migration failure

[Niraat]

I have a cluster and HA configured. One of the servers shut down and its virtual machines tried to start up on another server, but they couldn't do so. Now server 1 has started up and I can't return the virtual machines. Can you help me? This was the error I got:

Hi @Niraat , this is a good example why one should be careful with assigning VMs as HA resources, i.e. not having local disks.

Is the VM currently stopped? qm status 109
Does the original host have the referenced disks? (pvesm list local-lvm)

If the VM is stopped and the disks are present on the server1, you can manually move the VM config file
mv /etc/pve/qemu-server/109.conf /etc/pve/nodes/server-1/ (syntax may need to be adjusted)

Now you should be able to star the VM.
