Qdisk is normally used to watch network paths and advertise via a
non-network channel (i.e. a SAN) about a node's viability in the
cluster...

Using qdisk over iSCSI (or gnbd) is doable, but you'd have to have it on
a private, iSCSI-only network for it to make any sense. (i.e. treat the
iSCSI network as a SAN which only has SAN traffic).

I don't know the implications of using TOE vs. non-TOE for your
configuration.  Someone else will have to answer that one.
