Hi,all: I got the same problem.I checked out the code from cvs in Dec 3 2004. The OS is FC3 ,with it's own kernel,I only have one node which is DELL 1850. After the cluster was builded with "cman_tool join", I got Version: 3.0.1 Config version: 1 Cluster name: alpha Cluster ID: 3169 Membership state: Cluster-Member Nodes: 1 Expected_votes: 1 Total_votes: 1 Quorum: 1 Active subsystems: 0 Node addresses: 192.168.200.71 I executed the command "fence_tool join", then , I saw the words "cluster is not quorate. refusing connection" in file /var/log/messages.

Dec 11 15:30:12 OW-SRV-01 ccsd[3084]: Error while processing connect: Connection refused ... And the command was blocked there for a long time. Then I striked "CTRL + c" . the messages was also stopped. So what's the matter?
