We usually use only cman, gfs2 and drbd - does corosync replace cman or it's an addon?

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.
