[Linux-cluster] How GULM works ?

["Filipe Miranda" <filipe miranda gmail com>]

When using the DLM lock system, the CCSD pass on the structure
information to the CMAN. CMAN will be responsible for the cluster
membership, heartbeat, and cluster communication. All other layers above
  relay on CMAN.

If I'm using GULM, CMAN is not installed, how the architecture works in
this case?
