[Openstack-operators] rbd ephemeral storage, very slow deleting...

There was a bug in Havana where it would create the underlying RBD volume at 1024 times the actual size. We didn’t notice this until we started deleting instances and they took forever. 
Could be the case with you too?

I don’t think this made it into Havana sadly.
