RabbitMQ: Reset Mnesia before joining existing cluster
We should reset Mnesia always beore joining cluster. Any necessary data
will be fetched from live node(s), so why care? Not doing so could led
to stuck node which needs manual repair.
Why bother with these Mnesia bytes? Better kill it and refetch!
