How to add Cluster or Node in Proxmox VE

There are three Clusters or Notes as Following :-

Cluster-1 or Node-1 :- 192.168.1.10
Cluster-2 or Node-2 :- 192.168.1.11
Cluster-3 or Node-3 :- 192.168.1.12

All settings can be done via command pvecm (Proxmox Virtual Environment cluster manager)

Step-1 :- Create the Master Cluster

Login via ssh to the first Proxmox VE node or cluster. Use a unique name for your Cluster, this name cannot be changed later.

node-1# pvecm create node-1

node-1# pvecm status (To check the state of cluster)

Step-2 :- Adding nodes to the Cluster

Login via ssh to the other Proxmox VE nodes. Please note, the node cannot hold any same VM´s. (If yes you will get conflicts with identical VMID´s – to workaround, use vzdump to backup and to restore to a different VMID after the cluster configuration).

node-2# pvecm add 192.168.1.10 (Add a node)

node-2# pvecm status (To check or display the state of cluster:)
