Removing a failed host permanently from proxmox cluster

In case a host has failed permanently (Eg more than 1 disk failure while using RAID 5, Motherboard failure, etc.) and there is no plan/option to connect the same host again to the cluster, we can remove it using:

1. SSH to one of the working nodes
2. See the list of nodes using:

   pvecm nodes

   The failed host will not be part of this output

3. Check if there is quorum

   pvecm status

4. If there is no quorum (Likely with a two-node cluster with 1 failure) then reduce the no of expected votes to 1

   pvecm expected 1

5. Now once quorum is there, delete the remaining node with its name. We can see the node name in "pvecm status" or on web UI.

   pvecm delnode <node-name>
