For reference: https://issues.apache.org/jira/browse/ARTEMIS-2690 was (Author: slovdahl): For reference: https://issues.apache.org/jira/browse/ARTEMIS-2690 > Race condition between failover processing and master restart can cause split > brain > ----------------------------------------------------------------------------------- > > Key: ARTEMIS-2568 > URL: https://issues.apache.org/jira/browse/ARTEMIS-2568 > Project: ActiveMQ Artemis > Issue Type: Bug > Affects Versions: 2.10.1 > Reporter: Bob Mitchell > Priority: Major > > We have seen split brain in the following sequence of events when using > replicating backups with failback: > # Master fails or is shutdown > # Backup detects failure and starts to failover > # Master is restarted before Backup becomes "live" > # It's check for a "duplicate" server fails because backup is not live yet > # Master and backup both become live. > At the very least, we would like to see the window for this to occur to be > reduced, possibly by having the backup check again for the master to be > available just before going live. It might also be necessary to have the > master check for a duplicate server as a last step before going live as well. -- This message was sent by Atlassian Jira (v8.3.4#803005)
