Open Stack

Hi,

I'm trying to figure out the recommended configuration for RabbitMQ for 
use by OpenStack.

At 
"http://docs.openstack.org/high-availability-guide/content/s-rabbitmq.html" 
it says,

"There is an alternative method of configuring RabbitMQ for high 
availability. That approach, known as active-active mirrored queues, 
happens to be the one preferred by the RabbitMQ developers—however it 
has shown less than ideal consistency and reliability in OpenStack 
clusters. Thus, at the time of writing, the Pacemaker/DRBD based 
approach remains the recommended one for OpenStack environments, 
although this may change in the near future as RabbitMQ active-active 
mirrored queues mature."

In the same document at 
"http://docs.openstack.org/high-availability-guide/content/_configure_rabbitmq.html" 
it has instructions on how to configure rabbitmq as active/active with 
mirrored queues.

Is the comment about active/standby being preferred still current or is 
it stale?

Which is the recommended configuration?

Thanks,
Chris
