The whole point of qdisk is to have a shared disk on which the nodes can
test their conditions. If you read the qdisk entry in the RHCS Admin
manual  you would quickly understand why this is the case. Also
recommended reading is the Red Hat Magazine qdisk article .
In your case you can still have a two node cluster, remove the invalid
qdisk block, set two-node mode and expected votes 2. A single ip ping
test as a tiebreaker is probably not the best way to use qdisk anyway
and I would expect the two-node mode to work almost equally well.
