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 [1] you would quickly understand why this is the case. Also
recommended reading is the Red Hat Magazine qdisk article [2].

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.
