August 2007 01:45 To: linux-cluster@redhat.com Subject: [Linux-cluster] qdisk votes not in cman<o:p></o:p> </div> <o:p> </o:p> I have a cluster running RHEL5 U1 beta with two nodes and a quorum disk (at least it's in the cluster.conf file). However, when I run cman_tool nodes and cman_tool status, I don't see the qdisk votes represented. I've confirmed that qdiskd is indeed running. I'd appreciate it if someone could help point me to my mistake here. Thanks in advance.
