[Linux-cluster] Antwort: Re: Antwort: Unable to start cman on FC12 VM's Cluster3

OK what do you mean with did not want to start.

If cman starts there are subpoints.

Which of these subpoints/subservices failed to start ?

A two node cluster is of course the most difficult setup.

>From my experience, try to use a quorum disk too.

In any case you have to use a fence device!!!!

Hi Bernd,
 
Even with fence devices it did not want to start.
 
Yes, things are well defined in each node's /etc/hosts, I have an entry 
for each node (FQDN and hostname).

Hi, 

first of all you should define a fence device. 

And did you check dns or host file for your clusternode-names ?

[Linux-cluster] Unable to start cman on FC12 VM's Cluster3









Hi,

I'm fighting with cman on 2 FC12 VM's (KVM).

I'm unable to start cman.

Below my cluster.conf
------------------------------------------------------------
<?xml version="1.0"?>
<cluster name="fccl1" config_version="3">

 <clusternodes>
                <clusternode name="node1.localdomain" votes="1" 
nodeid="1"/>
                <clusternode name="node2.localdomain" votes="1" 
nodeid="2"/>
 </clusternodes>
                <cman expected_votes="2" two_node="1"/>
 <fencedevices>
 </fencedevices>

 <rm>
   <failoverdomains/>
   <resources/>
 </rm>
</cluster>
--------------------------------------------------------------

when running service cman start, it times out and complains that it
cannot join the cluster (timeout waiting for cluster), despite that
corosync is started.
Disabled selinux, nodes are referenced in each node's /etc/hosts.

Any idea ?
