Hi Fuelers, I recently got a question from one of the prospects - what should Fuel user do if one of the OpenStack controllers fails (completely) and there's a need to replace it with new box.
My educated guess was: 1. Remove controller from the environment in Fuel UI (*Q1:* is it actually possible? assuming that server is out and Fuel won't be able to do cleanup) 2. Get new controller discovered 3. Add new controller to the environment in Fuel UI (*Q2:* how does this happen right now? Does Fuel re-reploy all controllers? Will cloud experience services downtime? Will DB state be preserved?) Is it anywhere close to reality? Do we actually test the cases like that?
