Hello. As a part of the infrastructure change we are planning to rename the servers running ceph-osd, ceph-mon and radosgw services. The IP addresses will be the same, it's only the server names which will need to change.
I would like to find out the steps required to perform these changes? Would it be as simple as changing the /etc/hostname, /etc/hosts files and changing the radosgw info in /etc/ceph/ceph.conf and performing a server reboot? Would all the ceph services start okay after the name change? If not, what are the proper steps in changing the hostnames? We have a very small cluster (3 physical servers running ceph-mon/osd and two of theservers are running radosgw service), so we can't really remove the servers from the cluster. Many thanks for your help and ideas Andrei
