I'd suggest that if an app is so critical that you need to maintain HA even during maintenance, it's time for a 3rd node. Would you really ever want to send live traffic to a node undergoing maintenance?
- Erlend_123973Feb 03, 2015NimbostratusWe would like to send traffic to it in the period we are waiting for persistant connections to go away, but not during the maintaince. I agree it its time for a third node.
- Christopher_BooFeb 03, 2015CirrostratusI think priority groups might accomplish what you want. Move the node you want to work on to a lower priority group when you want to do maintenance. In the time you are waiting for active connections to go away on that node, it will still be available should the higher priority node fail.
