Situation
Cluster Volume Broker (CVB)
The CVB module is a cluster-aware application that enables you to make a change to an NSS volume on one node only, after which CVB distrubutes that change across all nodes. In other words, CVB ensures that each node in the cluster has the same image of the storage at all times.

Resolution
If you feel this is incorrect or corrupt you can rebuild the CVB.
From any node
echo -n "CVB REBUILD"> /proc/ncs/cluster
In the /var/log/messages file you will see an entry "Rebuild command issued to all nodes".
