what is the best practice for rolling upgrades for a cluster of Karaf servers? I mean to say that we have 2 nodes in the cluster and we want to update/upgrade software on server 1 but keep server 2 on the previous version temporarily until everything is stable with the upgrade on server 1 then upgrade server 2.
If we are using Cellar, the config, features and bundles will be always replicated as long as both servers are running. Also, what exactly is handling the failover for karaf instances in a cluster? Is it Karaf itself, cellar or hazelcast, or the software/hardware load balancer? thx. -- View this message in context: http://karaf.922171.n3.nabble.com/rolling-upgrades-to-Karaf-Cellar-tp4034531.html Sent from the Karaf - User mailing list archive at Nabble.com.
