Original GitHub issue: https://github.com/Corsinvest/cv4pve-autosnap/issues/44

The tool worked for me for a few days and then stopped working.
I am using proxmox 6.3.3 from no-subscription channel.
In my cluster some nodes are shut down. This is the only obvious thing that might be different for my cluster compared to others.

Hi the problem is the unknow vm.

 "id" : "qemu/103",
      "node" : "pve",
      "status" : "unknown",
      "type" : "qemu",
      "vmid" : 103

Look how to solve the problem.

Best regards

Hi, thanks for your fast responses.

Do you mean you will look how to solve the problem, or I should look how to remove the VMs?

The unknown VMs are part of the nodes which are shut down.
I would like to keep the VMs on the shut down nodes.

Best regards
