I need to shut down ceph for maintenance to make some hardware changes. Is it sufficient to just stop all services on all nodes, or is there a way to put the whole cluster into standby or something first? And when things come back up, IP addresses on the cluster network will be different (public network will not change though). Is it sufficient to just change the config files and the osd's will register themselves correctly, or is there more involved?
