No, the metadata "whiteboard" is shared. Just one copy that you removed.
Once node 3 start reporting again, it will simply put new content in there.
Not sure about vdsm, maybe some component (vdsm, engine) is still trying
to get status of node 3. I have been away for too long, so Didi will have
to pitch in.

It should be safe in global maintenance, the only risk is when you remove
the report of a node that currently runs the engine. As other nodes might
decide that the engine needs restarting.
