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 ?
