Thanks, I've managed.
I find the functionality half-baked. If you have a disable, it's only natural you want an enable action. And you do expect it to work.

You also expect 'stop' to work on active service, regardless if they are enabled or disabled (in my case, I've disabled before stopping them).
I've opened https://bugzilla.redhat.com/show_bug.cgi?id=1161501 to track the issue.

Lastly, I've mentioned but not filed a bug - on secondary compute nodes, openstack-utils RPM is not installed (Packstack-based installation), making stopping/starting the openstack related services a bit different than on the controller node.
