Dear Susant, Apparently the glistered process was stuck in a strange state. So we restarted the glusterd process on stor106. This allowed us to stop the volume, and reboot. I will start a new rebalance now, and will get the information you asked during the rebalance operation. I think it makes more sense to post the logs of this new rebalance operation.
