I had a similar problem... Ensure that each node has an entry in /etc/hosts for all the other nodes in the cluster (including itself). And most importantly, ensure (in /etc/hosts) that the <a href="http://127.0.0.1">127.0.0.1 </a> line does NOT have a listing containing the host name of the host, it should be listed as localhost localhost.localdomain ONLY!!. After you make changes the easiest is to simply reboot. <div> On 7/17/06, Stephen Gilbert <<a href="mailto:linuxelf@gmail.com">linuxelf@gmail.com</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div>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. [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? </div><div> -- Stephen Gilbert RHCE - 804006953620491 </div> _______________________________________________ rhn-users mailing list <a onclick="return top.js.OpenExtLink(window,event,this)" href="mailto:rhn-users@redhat.com">rhn-users@redhat.com</a> <a onclick="return top.js.OpenExtLink(window,event,this)" href="https://www.redhat.com/mailman/listinfo/rhn-users" target="_blank"> https://www.redhat.com/mailman/listinfo/rhn-users</a> </blockquote></div>
