Bug Description

charm-ceph-mon revision 37.

I have a ceph cluster with 3 monitors.

monitor-count is 3 in ceph-mon configuration.

I removed one ceph-mon unit but monmap was not updated causing
all the ceph commands to hang on any ceph monitor unit,
hitting connection timeout when trying to talk with the already removed units.

To fix this I had to manually remove the monitor following the instruction in:
http://docs.ceph.com/docs/luminous/rados/operations/add-or-rm-mons/#removing-monitors-from-an-unhealthy-cluster

There are known gaps in scaling back / scaling down OpenStack Charms.

The relation-departed Juju primitive is essentially NotImplemented across all of OpenStack Charms. That needs to be addressed on the higher level, as a concerted effort across the lot of charms.

We are tracking this type of issue with LP tag: "scaleback" in order to get a hit list of items to start with, and so that we can identify any common themes or areas where we should focus first.
