Hi Kolla Community, I would like to understand the current guidelines for adding or removing a controller node from an OpenStack cluster. With the introduction of quorum queues, we’ve observed that adding a new controller node causes a loss of quorum within the cluster. Consequently, during the reinstallation of a controller node, Masakari disables all the nova-compute services. Is this behaviour expected with quorum queues, or could this be addressed differently? Additionally, I’ve noticed that as soon as the Kolla containers are restarted in the cluster, clients are unable to connect, causing the cluster to go down. Could you please share insights or recommendations on how to handle this scenario effectively? Looking forward to hearing your thoughts. Thanks, Ishan Cisco Systems
