Remember, a quorum disk won't provide any votes until the quorum file
on it has been created.  This means the cluster has to exist without
needing the quorum disk to do so (and the quorum disk must be mounted).

You have EXPECTED_VOTES=3 yet you have 2 votes for the quorum disk
and 1 for each cluster member.  This adds up to 4, not 3.

With QDSKVOTES=2, your cluster cannot run unless you have your quorum
disk's votes.  See my first point about the quorum file being created.

My suggestion:  Set EXPECTED_VOTES=3 (like you already have) and set
QDSKVOTES=1.  This way your cluster can run if either both nodes are up
(with or without the quorum disk) or if one node plus the quorum disk
are available.
