Keep in mind also if you want to have fail over in the future. We were
running a 2nd server and were replicating via DRBD the raid arrays.
Expanding this storage is quite hastle, compared to just adding a few
osd's.

If I am not mistaken, the whole idea with the 3 replica's is dat you
have enough copies to recover from a failed osd. In my tests this seems
to go fine automatically. Are you doing something that is not adviced?

Is there a disadvantage to just always start pg_num and pgp_num with
something low like 8, and then later increase it when necessary?
Question is then how to identify when necessary

On a default luminous test cluster I would like to limit logging of I
guess successful notifications related to deleted snapshots. I don’t
need there 77k messages of these in my syslog server.
What/where would be the best to place to do this? (but not dumping it at
syslog)

I have seen messages pass by here, on when a monitor tries to join it
