Hi,

We have two RHEL5.1 boxes installed sharing a
single iscsi emc2 SAN, whitout fence devices. System is configured
as a high-availability system of xen guest.

One of the most repeating problems are fence_tool related.

# service cman start
Starting cluster:
Loading modules... done
Mounting configfs... done
Starting ccsd... done
Starting cman... done

Starting fencing... fence_tool: can't communicate with fenced -1

# fenced -D
1204556546 cman_init error 0 111

# clustat
CMAN is not running.

# cman_tool join

Sometimes this problem gets solved if the two machines are rebooted at
the same time. But in the current HA configuration, I cannot guarantee
two systems will be rebooted at the same time for every problem we
face. This is my config file:

###################################cluster.conf####################################

<?xml version="1.0"?>
<cluster alias="yoda-cl" config_version="2" name="yoda-cl">
<fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="3"/>
<clusternodes>
<clusternode name="yoda2" nodeid="1" votes="1">
<fence/>
</clusternode>
<clusternode name="yoda1" nodeid="2" votes="1">
<fence/>
</clusternode>
</clusternodes>
<cman expected_votes="1" two_node="1"/>
<rm>
<failoverdomains/>
<resources/>
</rm>
<fencedevices/>
</cluster>

Hi
 
I configured a two node cluster with no fence device on RHEL5.1.
The cluster started and stopped with no issues. The only difference that I see is that I have used FQDN in my cluster.conf
 
i.e., <clusternode name="yoda2.gsr.com" nodeid="1" votes="1">
 
Check your /etc/hosts if it has the FQDN in it.

Hi,
the problem of my cluster is that it start-up weel but after two days the problem that I have described is running, and this problem gets solved if the two machines are rebooted at the same time.
