[rules-users] Drools Workbench - VFS Clustering - Rpositories/Assets not synched

Wed Jun 11 00:24:41 EDT 2014

Hi,

I am deploying Drools Workbench with VFS Clustering in place. I have followed the steps defined in Drools-6 documentation in section "VFS-CLUSTERING", and the following link. But my repositories are not synching

http://mswiderski.blogspot.com.br/2013/06/clustering-in-jbpm-v6.html

but getting following Zookeeper exception.

NoNode for /jbpm-cluster/INSTANCES/nodeOne_11/MESSAGES/df7cda63-979b-47b2-ac9a-f2b218cb188

Attachment List

1.       Complete exception trace of zookeeper is pasted at the end.

2.       Server logs of both workbench servers is attached in the email.

3.       Server un-synched assets screen shot attached.

Problem
BPMN process created in Workbench-A is not getting Synched with Workbench-B. Following are the screen shots for the difference in project assets. Images attached in "ServerAssets.png"
