[jira] [Created] (ARTEMIS-2868) Split Brain on Replication could "damage" the Topology, isolating the server

Clebert Suconic created ARTEMIS-2868:
----------------------------------------

             Summary: Split Brain on Replication could "damage" the Topology, isolating the server
                 Key: ARTEMIS-2868
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-2868
             Project: ActiveMQ Artemis
          Issue Type: Bug
    Affects Versions: 2.14.0
            Reporter: Clebert Suconic
             Fix For: 2.15.0


The issue is that after a split brain, during a reconnect the live broker will send a topology update to the live replacing the topology.

 

As a result, new replicas will not be able to reconnect after the split brain, since the topology will return a wrong address, probably towards itself from backup.
