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">
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 ?

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
esta es mi vida e me la vivo hasta que dios quiera
