This commit adds additional control around how the galera cluster nodes are restarted during an upgrade (both the openstack upgrade as well as mariadb upgrade). lxc config that gets added during the lxc-container-create play would normally force a container restart. This commit essentially does the following: - run lxc-container-create on galera nodes but prevent container restarts from being triggered by the new lxc config that gets laid down - run a mariadb upgrade - run a controlled rolling restart of all mariadb cluster containers Change-Id: I5d979eb15c471274cc14ce6f41c8ae479c5131d6

upgrade:
|
|
- During upgrades, container and service restarts for the mariadb/galera
|
|
cluster were being triggered multiple times and causing the cluster to
|
|
become unstable and often unrecoverable. This situation has been improved
|
|
immensely, and we now have tight control such that restarts of the galera
|
|
containers only need to happen once, and are done so in a controlled,
|
|
predictable and repeatable way.
