The FAQ is incorrect probably because of context; I'll clarify it.  You
don't need to use *qdiskd* to prevent a 'fence duel' in the case that the
cluster is configured in the following way:

http://sources.redhat.com/cluster/faq.html#two_node_correct

... however, support for "diskless mode" is not implemented.  File a
bugzilla / feature request so we can track it?

You can't right now; it uses the quorum partition to converge on things
and do voting.
