Ryan Emerson commented on ISPN-8976:
------------------------------------

[~robertcernak] This did not make it into 9.3.0.CR1, however it is scheduled as part of our current sprint for 9.3.0.Final. So all being well the fix should be part of 9.3.0.Final which is due on 25/06/18

> 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.
