[Jboss-dev-forums] [Design of Clustering on JBoss (Clusters/JBoss)] - Re: Should nodes joining the cluster pull applications from

[ScottMarlowNovell <nu...@jb...>]

Issue #1 is about how an application that is deleted from the cluster could currently come back into the cluster.  Steps to reproduce:

a. Create a cluster with more than one node.  Lets assume three server nodes named { node1, node2, node3 }

b.  Deploy an application to the cluster, I used WineDemo.war.

c.  Bring node3 down.

d.  Delete WineDemo.war from the cluster.  Note that it didn't get deleted from node3's farm folder as node3 is down.

e.  Bring node3 back up, WineDemo.war is still running on node3.

The workaround for this issue is to manually remove WineDemo.war from node3 before bringing it back up.

I create task http://jira.jboss.com/jira/browse/JBCLUSTER-49 for this.
 
The second problem, issue #2 needs to be tested (I think it might be a problem).

To answer your question, the nodes only propagate in one direction when the node comes online (nodes pull applications from the cluster during this event but not push).
