so i checked codes, and found locations of exception in neutron/db/quota/driver.py：
    plugins = directory.get_plugins()
    plugin = plugins.get(key, plugins[constants.CORE])
    used = resource.count(context, plugin, tenant_id)
and plugin was always ML2Plugin.

I found that Only TrackedResource type could get used quota info, but CountableResource type could not and throw exceptions

So this issue happens only on Ocata? Or on all versions of Neutron?

i have resloved this bug, actually, maybe not a bug. It was my fault when merge codes into my ocata release, sorry!
