Hi everyone,

I've got a new deployment of Juno backed by Ceph set up and am getting a
rather unhelpful error message when attempting to download a stored image
out of Glance. I have no trouble uploading images or listing the image
details, and I'm able to manually manipulate and copy the image file with
the rbd client, so I'm fairly certain my Ceph permissions and connections
are working properly. Any help resolving this would be greatly appreciated.
The error is as follows:
