[infinispan-issues] [JBoss JIRA] (ISPN-8976) 2 subclusters failed to merge to 1 cluster - IllegalLifecycleStateException

2 subclusters failed to merge to 1 cluster - IllegalLifecycleStateException --------------------------------------------------------------------------- Key: ISPN-8976 URL: https://issues.jboss.org/browse/ISPN-8976 Project: Infinispan Issue Type: Bug Affects Versions: 9.1.4.Final Reporter: Robert Cernak Assignee: Ryan Emerson Attachments: logs.zip At the beginning I have main cluster consisted of 8 nodes. Then I disconnected main switch on which these nodes were connected. This leaded to separating main cluster to 2 subclusters - first with 2 nodes and second with 6 nodes. This was expected. After that I rebooted the nodes. After reboot, nodes again correctly formed 2 subclusters with 2 and 6 members. After a long time when all nodes were stable with low cpu load, I connected the main switch back which should lead to recreation of main cluster with 8 controllers. However main cluster did not recovered: subcluster2 did not change - still had 6 nodes connected - no new members subcluster1 - nodes did not connect with subcluster2 and after cca 30min they left the cluster. When I checked infinispan logs of node1 from 1st subcluster I had IllegalLifecycleStateException for every created cache (see included logs.zip): [transport-thread-744a974a-2811-4f79-ac63-f32daf005d7f-p4-t6] (ClusterCacheStatus.java:599) - ISPN000228: Failed to recover cache XXX state after the current node became the coordinator org.infinispan.IllegalLifecycleStateException: Cache container has been stopped and cannot be reused. Recreate the cache container.
