It's sure not the design. So it's a bug. I can't affirm from personal
experience that filing bug reports against Gluster results in action, but
it's probably where to go with this.

I do know that it's not the Gluster-standard thing to use a crossover link.
(Seems to me it's the obvious best way to do it, but it's not a
configuration they're committed to.) It's possible that if you were doing
your replication over the LAN rather than the crossover that Gluster would
handle a disconnected system better. Might be worth testing.
