             Summary: [Artemis 2.x Upgrade] Replicated HA: Live and Backup do not form cluster and initial synchronization is not triggered
                 Key: WFLY-10078
                 URL: https://issues.jboss.org/browse/WFLY-10078
             Project: WildFly
          Issue Type: Bug
          Components: JMS
    Affects Versions: 13.0.0.Beta1
            Reporter: Erich Duda
            Assignee: Jeff Mesnil
            Priority: Blocker
         Attachments: server1-trace.log, server1.log, server2-trace.log, server2.log

Across all replicated HA tests I often see an issue that initial synchronization between Live and Backup was not triggered.

*Scenario*
# There are two Wildfly servers configured as replicated Live-Backup pair.
# Live server is killed/shutdown

*Expectation:* Backup server becomes active.
*Reality:* Backup server does not become active, because initial synchronization with Live server was not triggered.

*Users impact:* Replicated HA feature doesn't work properly.

*Blocker* priority was set because this is regression against previous Wildfly releases.

*Detail description of the issue*

In the trace log there is last message from the {{SharedNothingBackupActivation}} which says that it is waiting on cluster connection. It is interested that JGroups subsystem is booting after this message was logged. However I am not sure if this could cause the issue.
