Hi, I would have a question on database HA feature in db.properties ( http://cloudstack-administration.readthedocs.org/en/latest/reliability.html#configuring-database-high-availability )
If I understand correctly, it is up to the admin to provide appropriate mysql HA (active-active, galera, etc) and ACS management server will JUST try to connect to slaves if the master is down ? We are running Galera, with haproxy/keepalived, and by using stoping haproxy, it takes i.e. 6sec for keepalived to detect haproxy is down, and failover IP to another host. During these 6 seconds, ACS managemnt server goes dead, because of this DB unavailability. So my wondering, is better to use ACS db HA feature, instead of loadbalancer for this specific purpose ? (we are also using haproxy/keepalived for management server loadbalancing - 2 servers in backend...) Any experience shared is really appreciated ! -- Andrija Panić
