[Clustering/JBoss] - Cluster merge issues
by jbossmk
We have a cluster of nodes deployed on the same machine with the cluster-service.xml having the following snippet:
<TCP bind_addr="localhost" start_port="${jboss.cluster.tcp.port:7800}" loopback="true"/>
| <TCPPING initial_hosts="localhost[${jboss.cluster.tcp.port:7800}]" port_range="${jboss.cluster.tcp.port.range:5}" timeout="3500"
| num_initial_members="${jboss.cluster.tcp.members:5}" up_thread="true" down_thread="true"/>
| <MERGE2 min_interval="5000" max_interval="10000"/>
| <FD shun="true" timeout="5000" max_tries="5" up_thread="false" down_thread="false" />
| <VERIFY_SUSPECT timeout="4000" down_thread="false" up_thread="false" />
| <pbcast.NAKACK down_thread="true" up_thread="true" gc_lag="100"
| retransmit_timeout="3000"/>
| <pbcast.STABLE desired_avg_gossip="20000" down_thread="false" up_thread="false" />
| <pbcast.GMS join_timeout="5000" join_retry_timeout="2000" shun="false"
| print_local_addr="true" down_thread="true" up_thread="true"/>
| <pbcast.STATE_TRANSFER up_thread="true" down_thread="true"/>
|
When a split happens, the nodes from the secondary partition doesn't merge at all. We are re-starting the node every time this happens.
Could someone tell me if there is anything wrong in the configuration?
Would setting shun="true" in the GMS change the behavior? I also heard that the JGroup channel's AUTO_RECONNECT should be set to true programatically, how do we do that declaratively?
Your help is appreciated.
Thanks.
