Justin Bertram resolved ARTEMIS-2421. ------------------------------------- Fix Version/s: 2.11.0 Resolution: Fixed > Implement periodic journal lock evaluation > ------------------------------------------ > > Key: ARTEMIS-2421 > URL: https://issues.apache.org/jira/browse/ARTEMIS-2421 > Project: ActiveMQ Artemis > Issue Type: Bug > Components: Broker > Affects Versions: 2.6.4 > Reporter: Gaurav > Assignee: Justin Bertram > Priority: Critical > Fix For: 2.11.0 > > Attachments: broker_master.xml, broker_slave.xml > > Time Spent: 1h 50m > Remaining Estimate: 0h > > We have Live-Backup server configuration, single instance of Artemis Live > server (2.6.4 version) backed up by single instance of Backup server. > Using shared file system as persistent storage. > Please refer attachments for both Live-Backup broker configuration. > *Fail Over Scenario* > # Node 1 acting as Live node and serving requests whereas Node 2 acting as > standby or passive node. No consumer is connected to these nodes > # Pushed 5 messages and verify message count as 5 > # Perform NIC (Network) failure on Node 1 server ( i.e. Cluster is now > unable to connect to Node 1) . This will make Node 2 as Active and we are > also able to see previous 5 messages (pushed in step 2) successfully > replicated on Node 2 > # Bring the network connection back for Node 1. This is where we are facing > issues as now both nodes acting as Live nodes and getting continuous error as > below: > {quote}{{{color:#FF0000}AMQ212034: There are more than one servers on the > network broadcasting the same node id. You will see this message exactly once > (per node) if a node is restarted, in which case it can be safely ignored. > But if it is logged continuously it means you really do have more than one > node on the same network active concurrently with the same node id. This > could occur if you have a backup node active at the same time as its live > node. nodeID=cd323206-4adc-11e9-814b-506b8d4ee653{color}}} > > {quote} > This situation bring entire cluster in inconsistent state and able to push > messages on both the nodes. > Any pointer on this issue is much appreciated! -- This message was sent by Atlassian Jira (v8.3.4#803005)
