We're in the process of building a small, 2-node cluster using RedHat Enterprise 4 and RedHat Cluster Suite. The servers we are using are 64bit Quad CPU Dells. Here is the issue we are having. When I launch system-config-cluster, I can build an initial cluster configuration. However, no matter what I enter in for Node Name, whenever I relaunch system-config-cluster, it says that I'm not part of a cluster, so I can't get the management pane. I've tried using my IP address, my hostname, and my fully qualified hostname. All have the same symptom. I try to start the service for ccsd, and it hangs for a long time, then succeeds. <meta http-equiv="CONTENT-TYPE" content="text/html; charset=utf-8"><title></title><meta name="GENERATOR" content="OpenOffice.org 2.0 (Linux)"><meta name="CREATED" content="20060717;14254500"><meta name="CHANGED" content="16010101;0"> <style type="text/css">  </style> [root@kpcobs2sdsit init.d]# time ./ccsd start Starting ccsd: [ OK ] real 3m9.990s user 0m36.147s sys 2m32.848s When I try to start cman (I'm going to be using dlm, not gulm), I just get a FAILED message. Nothing is written to /var/log/messages to explain why it failed. Now, here's another thing. In order to get ccsd to start, I had to install the RPM for gulm, because ccsd requires the magma-plugins package, which requires gulm. No problem, it's installed now. Suddenly, whenI go into system-config-cluster, it hangs for several minutes before telling me that I'm not part of a cluster. And now, I cannot configure a new cluster, because all of the drop-down menus (such as the list of available nodes to add to a failover domain) are empty. I've got an entry in Cluster Nodes, but it does not appear in the list under Failover Domains any more. As a test, I uninstalled the magma-plugins package, and the list now displays as it should, but of course, ccsd will not start. Any ideas on where I screwed up? -- Stephen Gilbert RHCE - 804006953620491
