Hi all! I wanted to check from your experience what would be the best approach to change the IP addresses of the engine and hosts on the management network. I have a 3 node cluster (in production) on ovirt 4.1 with engine and hosts resolving through /etc/hosts files on hosts and engine. The hosts have been added using their fqdn (host.domain) and not IP address, so what I will be changing is their IP and their domain part at /etc/hosts and to add them with their new domain at engine. Example /etc/hosts: 10.10.10.10 engine.domain 10.10.10.9 host1.domain 10.10.10.8 host2.domain 10.10.10.7 host3.domain I have also gluster storage configured on a separate network which will remain the same. How you would go for this with the minimum hassle? Is the engine going to complain or get confused with these changes? Many thanx, Alex
