It seems to be: Ceph will shuffle data to rebalance in situations such
as when we change the replica num or when some nodes or disks are down.

You can change the number replicas in runtime with the following command:
$ ceph osd pool set {poolname} size {num-replicas}
So it's absolutely safe to start with just 2 server, make all the
necessary tests and when ready to go in production, increase the
servers and replicas?
