Hi, I use rhel6.3 with packages :
cman-3.0.12.1-32.el6.x86_64 rgmanager-3.0.12.1-12.el6.x86_64 openais-1.1.1-7.el6.x86_64 I have two virtual nodes (vmware) and a quorum share disk (it's a virtual disk i use scsi sharing multi-write) the cluster work sometime. if i reboot node2 the cman not start i have : *Waiting for quorum... Timed-out waiting for cluster.* On the log corosync i have : *Jul 20 10:51:22 corosync [TOTEM ] A processor joined or left the membership and a new membership was formed. Jul 20 10:51:22 corosync [CPG ] chosen downlist: sender r(0) ip(192.168.10.154) ; members(old:1 left:0) Jul 20 10:51:22 corosync [MAIN ] Completed service synchronization, ready to provide service. Jul 20 10:51:23 corosync [CMAN ] quorum device unregistered* On the node1 when i type clustat i have : Cluster Status for clusterweb @ Fri Jul 20 10:38:57 2012 Member Status: Quorate Member Name ID Status ------ ---- ---- ------ server-1 1 Online, Local server-2 2 Offline /dev/block/8:16 0 Online, Quorum Disk If i restart cman on node1 and i restart cman on node2 the cman start properly a When i type clustat on both nodes i can see all online. I don't understand why i must restart on node1 the cman if i want to add the node2 on the cluster . You can see my cluster.conf <?xml version="1.0"?> <cluster config_version="6" name="clusterweb"> <clusternodes> <clusternode name="server-1" nodeid="1"/> <clusternode name="server-2" nodeid="2"/> </clusternodes> <cman expected_votes="3"/> <quorumd label="quorum"> <heuristic program="ping -c3 -t2 192.168.254.254"/> </quorumd> </cluster> Very thanks for your help Best regards.
