I think your analysis is right.  However, just for completeness I'll
note that quorum doesn't need shared storage.

To do drive-mirror without shared storage, what you do is run an NBD
server on the destination and point mirroring on the source to the NBD
server.  Similarly, an NBD server on the secondary machine would let
quorum do remote replication without shared storage.
