The mirror02 mirrors were booted on flavors that were much larger than
necessary and didn't have external volumes attached for teh cache
content. I've gone ahead and booted replacement Noble nodes using a
smaller flavor naming them mirror03 and attached a volume to each one
for caching.
We pull mirror02 out of the inventory as we don't need it anymore
(mirror01 is in use in production and will be cleaned up in followups).
