Currently the Python SDK doesn't support the URL parameters available in actions. For example, the action that deactivates a host has a "stop_gluster_service" parameter, but it is impossible to use it with the Python SDK because the signature of the corresponding method is like this: def deactivate( self, action=params.Action(), correlation_id=None ) To support these parameters the signature should be like this: def deactivate( self, action=params.Action(), correlation_id=None, stop_gluster_service=None )
