you'll found your cluster partitioned and if you "<cman two_node="1" expected_votes="1">" as redhat setting our cluster maybe you get data corruption
Because every node can operate with one vote an rich the quorum state
Forse the fencing problem redhat implement a work around as permanent solution
fence delay for some cluster agents
For fence_scsi in Redhat 5.X the redhat support says it's ok for production BAAAAA not tre
AND i the redhat technical tells the cluster don't require the quorum disk
UMMMMMMMMMMMMM

A qdisk is just another way to maintain quorum in cluster. there is a special two node cluster mode designed to allow for quorum to be maintained by the surviving node.
<cman two_node="1" expected_votes="1"></cman>
But it's not very clear to me what happens with fencing if both nodes get partitioned on the network. Do they both try to fence each other off ?

Subject: Redhat without qdisk
Hello all List
I have a big question about qdisk in a two cluster
one of out clients has too many cluster in two nodes configuration and one RedHat technical came to us and said that there is no need to use the qdisk
I would to know if this is true
I really think it's a bad idea
