[rabbitmq-discuss] about "exactly" policy on RabbitMQ 3.0.1

[t.otoda.freemail at gmail.com]

Hello,

I have 2 questions about "exactly" policy on RabbitMQ 3.0.1 .

Can anyone tell me  answers of my questions ?

 

1. How does RabbitMQ select nodes that queue is mirrored to in the cluster ?

   I want to know
   whether all mirrored Queue is mirrored to same 3 nodes,
   when there are more than 3 nodes in the cluster.


2. With the following cases, 
   what does RabbitMQ set "exactly" policy do ?

# As a premise,
# I suppose ha-params to be 3.

  1) 1 node ( named A) to which Queue is mirrored goes down
  
     I want to know
     whether RabbitMQ continue to publish messages to other 2 nodes (named 
B and C)
     without data lost.

  2) after 1), A is recovered

     I want to know
     whether Queue is mirrored to it again.

  3) instead of 2), another node ( named D ) is added in the cluster
  
     What should I do to allow Queue to be mirrored to D
     instead of A ?


Thank you
