Thanks Steve!

Yep, everything is a disk node

The node stopped/started was a disk node

first?

We didn't restart the whole cluster, just these two nodes in the cluster.
The other nodes were running happily.

Yeah, I read about the HA mirrored queues and such but due to our
throughput and the way rabbit replicated at the time, it made more sense
for us to use DRBD. So we aren't using any of Rabbit's HA features at this
time.

I'll look through the change logs and maybe upgrade our dev cluster and
see how it goes. Thanks!
