Re: [Linux-cluster] two nodes can't see eachother.



Hi Vincent,

as far as I know, the nodes talk each other using multicast.
It looks like they are connected by something (a switch?) which doesn't allow multicast to pass. May be you could try to connect the nodes using a simple HUB... if it works then that was the problem.

Cheers,
Daniela

I set up a two nodes cluster (centos 5.2) but I've got the following probleme...

Here is my cluster.conf file :

[root master ~]# cat /etc/cluster/cluster.conf
<?xml version="1.0"?>
<cluster alias="cluster2" config_version="6" name="cluster2">
<fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="3"/>
      <clusternodes>
              <clusternode name="noeud01.cluster" nodeid="1" votes="1">
                      <fence/>
              </clusternode>
              <clusternode name="master.cluster" nodeid="2" votes="1">
                      <fence/>
              </clusternode>
      </clusternodes>
      <cman expected_votes="1" two_node="1"/>
      <fencedevices/>
      <rm>
              <failoverdomains/>
              <resources/>
      </rm>
</cluster>

 From the node master.cluster, the clustat command shows this :
[root master ~]# clustat
Cluster Status for cluster2 @ Wed Feb 25 23:24:21 2009
Member Status: Quorate

Member Name                             ID   Status
------ ----                             ---- ------
noeud01.cluster                             1 Offline
master.cluster                              2 Online, Local


And from the node noeud01.cluster, the clustat command shows this :
[root noeud01 ~]# clustat
Cluster Status for cluster2 @ Wed Feb 25 23:26:17 2009
Member Status: Quorate

Member Name                             ID   Status
------ ----                             ---- ------
noeud01.cluster                             1 Online, Local
master.cluster                              2 Offline

I can successfully ping noeud01.cluster from master.cluster and master.cluster from noeud01.cluster

I don't understand what the two nodes can't see eachother.


Thanks for your help;
Best regards

Vincent
