I suggest the following text for the release note:

HA mode allows setting up a single MongoDB instance as a Ceilometer backend.

Fuel 5.0.1 installs MongoDB as a Ceilometer backend. When installing OpenStack in HA mode, Fuel does not enforce user to setup several MongoDB nodes. As a result, user can setup a single MongoDB instances for Ceilometer, which is not acceptable for HA environment. To avoid the issue when setting up OpenStack in HA mode, make sure that you configure Fuel to setup MongoDB on more than one OpenStack controller.

Where are the release notes posted? Are they posted to the docs repository as well? If so, I'll assign this t myself and write the appropriate docs page.

In 5.1 it possibly should be added the checking that in HA mode MongoDB is also set in HA mode (on UI side) - that it'll be at least 3 Mongo instances there - not necessary on the controllers, but 3 at least.
