<div>Also, last time we checked, if you are using cells, then it
doesn't play nice with H/A Rabbit. I could have missed that
update that has fixed this, but it's something to keep in mind if
you are using them or plan to in the future as you scale.</div>

<div>My personal experience is that rabbit HA cluster seems to eat
itself every couple of weeks. It's pretty harsh, have to kill all
cluster nodes, blow away mnesia, then it'll come back. <br>

OpenStack HA guide (<a href="http://docs.openstack.org/high-availability-guide/content/s-rabbitmq.html" target="_blank">http://docs.openstack.org/high-availability-guide/content/s-rabbitmq.html</a>)
says that Pacemaker/DRBD approach is preferred over active-active
mirrored queues. Details are sparse in the guide. Is anyone aware
of any data/issues first hand?<br>

Thanks for any pointers.<br>
