Hi Everyone, I have a two-node cluster. I have built and installed the cluster sources from cluster_0406282100 snapshot. I can bring up both nodes successfully, however, seems like I have a brain split cluster in that each node thinks it is the only node. I ran the cman_tool on each node as follows: cman_tool join -c OVLCluster -2 -n nodename Furthermore, in the log messages I often see messages that require one of the nodes to be rebooted. Some times I see the message in both nodes' /var/log/messages files. In this case, I reboot the node that needs to be rebooted and run the "fence_ack_maual -s rebooted-nodename" on the other system after the reboot. The problem is that then I see the same messages again on the rebooted node's messages file. Seems like the cluster is in some kind of a loop wanting to reboot that node over and over again after the reboot. Can anyone tell me what is going on? Also, I am running the ccsd, cman_tool, fence_tool, clvmd, vgchange commands by hand. What version of the clustering software has nice scripts such as "cluster start"?
