Proxmox Cluser 7.1

Hi,

I don't think the link you posted does what you wanted to do. This guide tells you how tell corosync how to use a different network not divide your cluster into individual independent nodes.

Removing a node is docmented here: https://pve.proxmox.com/wiki/Cluster_Manager#_remove_a_cluster_node

What is pvecm status saying on then nodes?
Sorry i did pasted the wrong link. But the one i follow is this https://pve.proxmox.com/wiki/Cluster_Manager#_remove_a_cluster_node you posted.

***I didn this in every node***
systemctl stop pve-cluster
systemctl stop corosync
pmxcfs -l
rm /etc/pve/corosync.conf
rm -r /etc/corosync/*
killall pmxcfs
systemctl start pve-cluster
pvecm delnode oldnode1 ( i had to do this removing every oldnode in every node)
pvecm expected 1
rm /var/lib/corosync/*
rm -r etcpve/nodes/

Then i Create a Cluster with another name y join every node again.
And my users, and everything worked again.

I recommend to use Proxmox Backup in this case, to have your info before doing this.
