[Linux-cluster] problem quorum cman


I use rhel6.3 with packages :


I have two virtual nodes  (vmware) and a quorum share disk (it's a virtual disk i use scsi sharing multi-write)

the cluster work sometime.

if i reboot node2 the cman not start i have   : Waiting for quorum... Timed-out waiting for cluster.

On the log corosync i have :

Jul 20 10:51:22 corosync [TOTEM ] A processor joined or left the membership and a new membership was formed.
Jul 20 10:51:22 corosync [CPG   ] chosen downlist: sender r(0) ip( ; members(old:1 left:0)
Jul 20 10:51:22 corosync [MAIN  ] Completed service synchronization, ready to provide service.
Jul 20 10:51:23 corosync [CMAN  ] quorum device unregistered

On the node1 when i type clustat i have :
Cluster Status for clusterweb @ Fri Jul 20 10:38:57 2012
Member Status: Quorate

 Member Name                                  ID   Status
 ------ ----                                  ---- ------
 server-1                                      1 Online, Local
 server-2                                      2 Offline
 /dev/block/8:16                           0 Online, Quorum Disk

If i restart cman on node1 and  i restart cman on node2 the cman start properly a
When i  type clustat on both nodes i can see all online.

I don't understand why i must restart on node1 the cman if i want to add the node2 on the
cluster .

You can see my cluster.conf

<?xml version="1.0"?>
<cluster config_version="6" name="clusterweb">
                <clusternode name="server-1" nodeid="1"/>
                <clusternode name="server-2" nodeid="2"/>
        <cman expected_votes="3"/>
        <quorumd label="quorum">
                <heuristic program="ping -c3 -t2"/>

Very thanks for your help

Best regards.
