Bug Description

Please see this email thread: https://lists.launchpad.net/fuel-dev/msg00254.html, where answers are provided. Basically we need to polish them and post to fuel-docs.

Questions to cover:
Q1. MySQL + Galera - is it an active/active HA? I was told/tend to think "yes", but want to understand it better. A simple workflow example would help

Q2. ceph-mon on controllers - same question as Q1

Q3. Neutron - is it in active/standy HA? I got this understanding from docs and want to understand why. I was told that Grizzly and Havanna support multiple l3 agents, but we don't leverage it on some reason in Fuel.
