I am currently using a n nodes configuration with a qdiskd process to

The simplest case is a two node :


<cluster config_version="79" name="xxx">
       <totem token="42000"/>
       <clusternodes>
       <cman expected_votes="3" two_node="0"/>

Add 'quorum_dev_poll="42000' to the cman tag.

I just found out a note describing this parameter :

http://kbase.redhat.com/faq/docs/DOC-2882

but It seams to deals with problems with multipath and cman interraction on one node. My problem seams to be a little bit different : I do stop qdisk and cman on node 1, and this triggers a temporary loss of quorum on the node 2.

I will try this parameter to see if I reproduce the problem.

Regards,

PS: what is the default value for this parameter ?
