Additional info: When I try to start cman, I see these messages in /var/log/messages: Sep 11 11:44:26 server01 ccsd[24972]: Connected to cluster infrastruture via: CMAN/SM Plugin v1.1.5 Sep 11 11:44:26 server01 ccsd[24972]: Initial status:: Inquorate Sep 11 11:44:57 server01 ccsd[24972]: Cluster is quorate. Allowing connections. Sep 11 11:44:57 server01 ccsd[24972]: Cluster manager shutdown. Attemping to reconnect… I see these messages in dmesg: CMAN: forming a new cluster CMAN: quorum regained, resuming activity CMAN: sendmsg failed: -13 CMAN: No functional network interfaces, leaving cluster CMAN: sendmsg failed: -13 CMAN: we are leaving the cluster. CMAN: Waiting to join or form a Linux-cluster CMAN: sendmsg failed: -13 This is almost always caused by a mismatch between the kernel and user space CMAN code. Update the CMAN user tools to fix the problem.
