Re: [Linux-cluster] cman_tool join causes other nodes to kernel panic



yes, I updated the cluster.conf by adding more nodes.  

e.g., I added a couple of these blocks (6 more nodes to be exact)

        <clusternode name="blade06" nodeid="1" votes="1">
          <multicast addr="224.0.0.18" interface="eth0"/>
             <fence>
               <method name="single">
                 <device name="human" ipaddr="129.58.15.6"/>
               </method>
             </fence>
          </clusternode>

I first updated the file (incrementing the version), and then ran:
 ccs_tool update cluster.conf
 cman_tool version -r 3

These commands completed without incident.  The failure occured when
running 'cman_tool join -w' on the new node.
