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?
Hi Filipe, The Gulm locking protocol has its own cluster manager and locking layers. The layers are all still there, but they're internal to Gulm. For cman, it's broken out into pieces like cman, dlm, lock_dlm, lock_harness, and so forth.
