[Linux-cluster] Conga Error: "... reports its cluster version is rhel4 and we expect rhel5"



Dear all,

I have two different problems when trying to configure two-node a Cluster:

1. When starting the daemons (using cman startup script), ccsd says
   immediately

 Cluster is not quorate.  Refusing connection.
 Error while processing connect: Connection refused


2. so I tried to modify the cluster configuration by Conga, but I
   received the following error message:

 The following errors occurred:
    * Node <hostname1> reports its cluster version is rhel4 and we
      expect rhel5
    * Node <hostname2> reports its cluster version is rhel4 and we
      expect rhel5



Both the nodes are running Scientific Linux 5.2 with kernel 2.6.18-92.1.18.el5xen i686

the following rpm are installed:
  modcluster-0.12.0-7.el5
  cluster-cim-0.12.0-7.el5
  lvm2-cluster-2.02.32-4.el5
  cluster-snmp-0.12.0-7.el5
  system-config-cluster-1.0.52-1.1

  cman-devel-2.0.84-2.el5_2.2
  cman-2.0.84-2.el5_2.2

I started configuring the cluster using the tool system-config-cluster.
I wanted a two-node cluster, using a quorum disk as 3rd vote. The quorum disk resides on a SAN connected via fiber channel. I inizialized it using 'mkqdisk ..." and both nodes can now correctly see it
  root# mkqdisk -L
  mkqdisk v0.5.2
  /dev/sdc1:
        Magic:                eb7a62c2

        Kernel Sector Size:   512
        Recorded Sector Size: 512


This is the cluster.conf file:

root# cat /etc/cluster/cluster.conf
<?xml version="1.0" ?>
<cluster alias="sicr_vm" config_version="7" name="sicr_vm">
        <cman two_node="0" expected_votes="2"/>

        </quorumd>
<fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="3"/>
        <clusternodes>
                <clusternode name="node1" nodeid="1" votes="1">
                        <fence/>
                </clusternode>
                <clusternode name="node2" nodeid="2" votes="1">
                        <fence/>
                </clusternode>
        </clusternodes>
        <fencedevices/>
        <rm>
                <failoverdomains/>
                <resources/>
        </rm>
</cluster>



Does anybody can help? I can'tfind where the mistake is...

Thank you,
cheers,
Daniela
