Hello Joost

i need to change the ip addresses of 3 proxmox servers that are in a cluster.
can someone tell me what the impact will be on the cluster?

in /etc/hosts you find the following line (example: IP is "192.168.22.111", nodename is "node1" domain is "mydomain.tld") :

192.168.22.111 node1.mydomain.tld node1 pvelocalhost

Do the following in all nodes:
- Define the new IP-address for the NIC (or bridge) you want to use
- adapt the IP-address in /etc/hosts accordingly
- Reboot

That´s all

Do not change the nodename (node1 in the example)!!

Kind regards

Mr.Holmes
