Senlin unsupported version

I think I got Senlin installed by throwing away the entire system and starting from scratch with DevStack. However, when I ran the "Verify" step (at the Senlin installation guide, I got this:

$ openstack cluster build info
Failed to contact the endpoint at for discovery. Fallback to using that endpoint as the base url.
Failed to contact the endpoint at for discovery. Fallback to using that endpoint as the base url.
The clustering service for :RegionOne exists but does not have any supported versions.

The command "openstack endpoint list --service senlin" returns three enpoints with that URL, for public, admin, and internal interfaces.

I looked in and near the end I see this:

2019-10-23 21:06:39.551 | [Call Trace]
2019-10-23 21:06:39.552 | ./
2019-10-23 21:06:39.554 | /opt/stack/devstack/lib/glance:335:die
2019-10-23 21:06:39.557 | [ERROR] /opt/stack/devstack/lib/glance:335 g-api did not start

Beyond that, I can't think of anything diagnostic to add. So my questions are:

  1. Is this a sign of an installation error?
  2. If the error is in Glance, where do I start on the diagnosis?

As always, any help is appreciated.

Thanks to dtruong, I decided that perhaps not being able to figure out how to use Senlin directly was not so bad, since my objective was and is to evaluate Heat. So I proceeded with the Heat installation, which actually seems to work. So it appears that Senlin is working correctly, I just didn't interpret correctly the behavior of the senlin-engine command.

Is your senlin-api service running? If you are using devstack, you should be able to see the status for it like this:

sudo systemctl status devstack@sl-api

If the output says that it is inactive (dead), then start it using:

sudo systemctl start devstack@sl-api

Thanks for your responses. I have been struggling and you are like a light at the end of the tunnel. These two commands both failed with the "could not be found" message:

$ sudo systemctl status devstack@sl-api
Unit devstack@sl-api.service could not be found.

I noticed that in my DevStack version, Glance does not appear to be running. With your comment on my other question, I launched senlin-engin in one console window. In another I launched senlin-api, but it failed to bind on (more on next comment)

Now all my 'openstack cluster ...' commands fail with "request() got an unexpected keyword argument 'global_request_id'". The tutorial at doesn't tell me what I need to do to have Senlin ready for commands. I believe that's what I need.
