Comment 4 Travis Nielsen 2020-08-07 14:09:47 UTC 
Rook only requires a single mon to seed the external cluster, but then it is expected that Rook will query for the full mon quorum periodically and update the configmap with the full set of mons.

@Rachael Was the mon down since OCS first connected, or did the mon go down after that initial connection? 

The rook operator log [1] is full of these messages. Since it says it could connect successfully, it doesn't make sense why it stilled the health check.

Neha, the cm "regression" is due to the bug and will be solved by my current PR.
Expect this to land today.

Thanks
