That is actually the manifestation of a bug in Nova that was addressed very late in Folsom. The short version is that Nova inconsistently scoped the ownership of volumes vs. instances so it was possible for an admin user to view a mixed set of resources which could lead to the scenario you hit where things are in one list but not the other. I'm not sure if there's any plans to backport the fixes from Nova. A patch could probably be worked up for the stable/essex Horizon branch that would avoid the keyerror (see the state of that code in Folsom: https://github.com/openstack/horizon/blob/stable/folsom/horizon/dashboards/nova/volumes/views.py#L68 ), but it would be papering over what is inherently a broken situation in Nova.
My advice from back in the Essex days was that you should be wary of using an "admin" user in the "Project" dashboard since the underlying APIs didn't handle it correctly. Alternatively, the Folsom Horizon release is actually backwards-compatible to an Essex stack, so you could try running Folsom Horizon which is less subject to many issues.

I do really need this (now not working) page :-) Regards, Christian Parpart.
