Hi Alan, thanks for support
I'm not familiar with stonish.
Sorry for mistyping, I have meant stonith.
So, does it make sense to use cman instead of corosync in case of two-node
cluster? 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.
