No, a cluster with just RAM node is very fragile and largely useless - it will
be faster for certain operations but it will use disc space anyway, see this
recent post for details:
http://lists.rabbitmq.com/pipermail/rabbitmq-discuss/2012-July/021096.html .

If you are really sure of what you're doing, you can simply stop & reset the
disc node to have a cluster with only RAM nodes - but you most certainly don't
want that.
