[Linux-cluster] RHEL4 U4's qdiskd without disk or partition



hi all,

i have a question regarding using ping for tie
breaker in a redundant NIC with a crossover for the qdisk daemon WITHOUT
the use of a disk/ partition.  Has anybody made this work in RHEL4 U4?

I'm still testing it and here's my very basic setup using
system-config-cluster:

<?xml version="1.0" ?>
<cluster alias="new_cluster" config_version="2" name="new_cluster">
        <quorumd interval="1" label="stewy" min_score="3" tko="10"
votes="3">
                <heuristic interval="2" program="ping -c 1 192.168.5.1"
score="1"/>
        </quorumd>
        <fence_daemon post_fail_delay="0" post_join_delay="3"/>
        <clusternodes>
                <clusternode name="cluster1" nodeid="1" votes="1">
                        <fence>
                                <method name="1">
                                        <device name="manual_fence"
nodename="cluster1"/>
                                </method>
                        </fence>
                </clusternode>
                <clusternode name="cluster2" nodeid="2" votes="1">
                        <fence>
                                <method name="1">
                                        <device name="manual_fence"
nodename="cluster2"/>
                                </method>
                        </fence>
                </clusternode>
        </clusternodes>
        <cman/>
        <fencedevices>
                <fencedevice agent="fence_manual" name="manual_fence"/>
        </fencedevices>
        <rm>
                <failoverdomains>
                        <failoverdomain name="test_domain" ordered="0"
restricted="0">
                                <failoverdomainnode name="cluster1"
priority="1"/>
                                <failoverdomainnode name="cluster2"
priority="1"/>
                        </failoverdomain>
                </failoverdomains>
                <resources>
                        <ip address="172.16.189.250" monitor_link="1"/>
                </resources>
                <service autostart="1" domain="test_domain" name="test"
recovery="relocate">
                        <ip ref="172.16.189.250"/>
                </service>
        </rm>
</cluster>

I can start ccsd, cman, fenced and rgmanager but qdiskd fails with qdisk
label 'stewy' not matching with any device.

Basically, I'm trying to do what's mentioned in the 'Note' of the FAQ16
where in we can use qdisk without a disk/ partition:

 http://sources.redhat.com/cluster/faq.html#quorumdiskhow

Any ideas?

Thanks,
Michael
