Are there any benefits in using cman? > CMAN is in addition to corosync, not instead of it. You need CMAN to handle split-brain network partitions. In a partition, CMAN is used to determine which partition has quorum, and shuts down the other partition. If you use qpidd --cluster-cman then qpidd will shut itself down if it loses quorum. You can also use fencing to shut down the inquorate hosts. Without cman, a split-brain partition will create two isolated qpid clusters, which will fail when the partition is removed. --------------------------------------------------------------------- Apache Qpid - AMQP Messaging Implementation Project: http://qpid.apache.org Use/Interact: mailto:[email protected] _______________________________________________________ The information contained in this message may be privileged and conf idential and protected from disclosure.
