Our Proxmox Servers have been moved to different location; hence, IP address have changed to a different network. I have gone in to change IP Addresses on all 3 Servers in the
/etc/network/interfaces
/etc/hosts

However, when when trying to change IP's and increment the config_version number in /etc/pve/corosync.conf, I get error message saying "/etc/pve/corosync.conf is meant to be read-only." Therefore, it does not allow me to change the IP Address of the servers in that file for the cluster. Is there a solution to change this file in order for the cluster to be functional again?

Thank you
