This make me thing that somewhere we could be using wrongly overcloud-full instead it's uuid that is 2a2bb369-8725-47c7-8858-efd2387d6917

Not sure if having configured multiple glance backend has something to do:


stores = glance.store.filesystem.Store,glance.store.swift.Store

#default_store = file
default_store = swift
