[jboss-user] [JBossCache] - Shunning not working
Hi,
I have 2 JChannels both of which have shun enabled. One channel is for JBoss itself and
the other is for my PojoCache. I have a cluster consisting of {A,B,C}. I unplug the
network cable for C. Each node detects the loss of the other node(s). I wait about 60
seconds then plug the cable back in. What I want is for {A,B} to continue in their own
cluster and C to continue in its own (separate) cluster. In other works, A and B reject
C's effort to rejoin the cluster.
What is happening is that C rejoins A and B and my cache is merged thus becoming corrupt
with C data. In other words, node C is not shunned by A and B and nodes A and B aren't
shunned by C. Each node is notified of the change via a merge view event. I still need to
receive this notification that a node tried to rejoin the cluster. I just want the rejoin
to fail without touching the cache.
Here is an excerpt from one XML config file:
