When adding an image member to a shared image, we get the following traceback on glance-api:

UnknownScheme: Unknown scheme 'file' found in URI
Related config is:
[DEFAULT]
enabled_backends = gpfs:file
[gpfs]
filesystem_store_datadir = /path/to/Openstack/Glance
If I'm reading this right, the issue is related to glance_store.location.SCHEME_TO_CLS_MAP being empty. This causes backend.get_location_from_uri to fail to look up the scheme.
I think this is happening because backend.py is populating location.SCHEME_TO_CLS_MAP, but multi_backend is populating location.SCHEME_TO_CLS_BACKEND_MAP. Because location.get_location_from_uri is only looking at SCHEME_TO_CLS_MAP, when it is called with a multi-backend config, it fails to find any registered schemes.
It looks like backend.py populates this
glance_store/multi_backend.py function create_multi_stores calling glance_store/location.py register_scheme_backend_map |
