Changing IP's of hosts in cluster

[onlinegeek]

Hi,
I'm redoing my home network this weekend. I've bene using the Netgear Orbi units for a while and have had one main network on 192.168.0.x range. My proxmox cluster has four hosts in this range which work well. I'm moving to Unifi and multiple vlans etc.
I know that in Proxmox I can easily change the ip of a host but if it change all four hosts and reboot, will there be any issues when they connect to the new vlans that i have? My concern is not the vlan/networking side but the cluster..... will it have issues etc? Do i need to remove the cluster before i change the ip addresses to then create a cluster afterwards? I like being able to migrate vm's from one cluster to another (paid feature in VMWare esxi but free in Proxmox)....

THanks

Hi,

it is possible to change the ip addresses on your nodes without having to recreate the whole cluster: this older post [0] already answers your question
(be cautious with the corosync config file [1])
