Well, I just upgraded Pacific to Reef 18.2.4 and the only problems I
ran into had been problems previously seen in Pacific.
Your Mileage May Vary. as the only part of Ceph I put a strain on is
deploying stuff and adding/removing OSDs, but for the rest, I'd look to
recent Reef complaints on the list and see if any of them apply.

Tim
