Ceph maintenance question

Hi everyone,

Quick and simple set of similar questions:

1. Before restarting a CEPH OSD, should you mark it as "Out"?
2. Before restarting a monitor, should you do anything?
3. Before restarting a node, should you do anything?
4. Before restarting a manager or manager node, should you do anything?

Thanks! I'm just a little concerned that I've been working on production equipment without enough caution lately, feeling nervous.
