Hello Robert, I changed ceph.conf and all the files containing IPs or hostname. How can I change the mon map inside the MON DB ?

That means that you changed the IP addresses of the cloned hosts? You cannot just change IP addresses, you have to rollout new MONs on the new IPs first. The MON IP is recorded in the mon map. I.e. you would have to manually edit the mon map inside the MON DB before being able to start the cluster. And you have to edit ceph.conf. The new cluster then still has the old cluster fsid which may or may not be an issue if you ever need to couple both clusters for replication.
