title: Rabbitmq cluster, when the node is offline, how to ensure that the offline queue receives messages from the fanout exchange?
body: <p>I have three node cluster, and two queues bound to one fanout exchange. My requirement is that all messages sent to the exchange must be saved to these two queues, all messages cannot be lost and must be processed.</p>
  <p>When one of the nodes is offline, the queue on the node will lose the message received by the exchange. I may be able to use Quorum Queues, but this can only allow one node to go offline. If two nodes are offline, the same problem will occur. Is there any solution?</p>
