http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_MRG/1.1/html/Messaging_User_Guide/chap-Messaging_User_Guide-Clustering_and_federation.html This section defines 2 different methods of clustering qpid without sufficient delineation between the two. Case 1: qpid + openais configured via openais.conf Features: active/active broker clusters support for redundant ring protocol does not support split-brain Case 2: qpid + cman configured openais via cluster.conf Features: HW nodes are clustered using ClusterSuite (from RHEL AP) qpid --cluster-cman option required openais.conf is not needed (??) cluster split-brian is supported
Fixed in the 1.2 clustering docs. I have not yet verified whether openais.conf is optional when using cman. Email out on that question.
openais.conf is not used when aisexec is started via cman.
