The ``PUT /os-services/disable``, ``PUT /os-services/enable`` and
``PUT /os-services/force-down`` APIs to enable, disable, or force-down a
service will now only work with *nova-compute* services. If you are using
those APIs to try and disable a non-compute service, like nova-scheduler or
nova-conductor, those APIs will result in a 404 response.
There really never was a good reason to disable or enable non-compute
services anyway since that would not do anything. The nova-scheduler and
nova-api services are checking the ``status`` and ``forced_down`` fields to
see if instance builds can be scheduled to a compute host or if instances
can be evacuated from a downed compute host. There is nothing that relies
on a disabled or downed nova-conductor or nova-scheduler service.
