Removing a ProxMox Cluster

Removing a ProxMox Cluster

Sometimes it is necessary to delete the created Proxmox cluster and create a new one. There are instructions on the network, but they are not suitable - after deletion the cluster does not work, but the old nodes hang gray (inactive) and it is not possible to assemble a new cluster.

First of all, we stop the cluster

rm -fr /etc/pve/nodes/*

systemctl stop pve-cluster

systemctl stop corosync

We are starting the cluster again in single mode

pmxcfs -l

Delete config files

rm /etc/pve/corosync.conf

rm -r /etc/corosync/*

We kill a single process, preferably several times.

killall pmxcfs

pmxcfs: no process found

e delete the list of nodes from the server, otherwise they will hang around there “dead”.

rm -fr /etc/pve/nodes

Let's turn on the cluster and enjoy life!

systemctl start corosync

systemctl start pve-cluster

Restart web muzzle

service pveproxy restart
