There's a bug in the one you have which is fixed in 4.5. Basically, the SM component of CMAN in the kernel wasn't getting notified when qdisk votes were causing a quorum transition. This caused problems with fenced and the DLM (and thus, rgmanager - since rgmanager uses the DLM). It's fixed in cman-kernel from 4.5 and later.
