Comment 9 for bug 1922251

Yeah, so it looks to me that glance tries to determine the store from the URI itself, as it calls this with nothing more than the URI provided:

https://github.com/openstack/glance/blob/922e544ca2556994450e6972403ba4313318c5e0/glance/common/store_utils.py#L159-L178

Which, as Lee suggested, goes along with not having a parameter (that I know of either) to provide the store name in the location update.

That function can fail if the scheme map isn't working, which makes me wonder about your stores= config:

stores = glance.store.filesystem.Store, glance.store.http.Store,glance.store.rbd.Store

which is different from how it's specified in our job:

stores = file, http, rbd

Could that be related?
