corosync is the messaging layer allowing cluster nodes to talk with each
other.
cman/rgmanager should sit on top of it.


try the following commands:
service corosync status
If the status is running the you are using it, otherwise not.

Also look into the /var/log/messages file for corosync.
If you are using corosync then there should be prints in there for corosync.
