Sunil,
Thank you for responding. I will try o2cb_ctl on Monday, when I have
physical access to hit Reset in case one or more nodes lock up.
If there really is a requirement to restart the cluster on wilson1 every
time
I add a new node (and I have five or six more nodes to add), that is too
bad. Wilson1 is a 24x7 production system.
