Remove Node from Cluster

If a node needs to be removed entirely from the cluster and still used after the removal the following must happen

1. Remove or mitigate all VMs and containers away from the node.
2. Run the following code

It may be best to run this line by line to see the output.

systemctl stop pve-cluster corosync
pmxcfs -l
rm /etc/corosync/*
rm /etc/pve/corosync.conf
killall pmxcfs
systemctl start pve-cluster
