This feature is called "redundant ring".  Multiring is a different
unimplemented feature.

Redundant ring was tested a long time ago very heavily for over 3 months
but really hasn't seen alot of field use/abuse since.  Testing since
development has been minimal since my second switch broke and I haven't
replaced it.

I can't really tell you what state it is in, other then it appears to be
broken for you :(  Chrissie may be able to provide you some idea of its
state.  She tests it occasionally with the full stack.

Unfortunately with the fc11 deadlines I am totally swamped attempting to
wrap up corosync before the fc11 merges close and don't have any time to
investigate further until corosync 1.0 hits the wire.
