This check does not require manually setting the number of expected OSDs. Initially, the charm sets the count (per-host) to that of what's present in the OSD tree. The count will be updated (on a per-host basis) when the number of OSDs grows, but not when it shrinks. There is a charm action to reset the expected count using information from the OSD tree.
