Hi Avi, 

If I understand correctly, you're looking at a way to implement this feature on the undercloud. Is that correct?

This might be difficult for two reasons:

1. The director installation doesn't include Cinder at all.
2. The director uses Swift as a Glance backend.

Can you elaborate on what kind of documentation you aiming for here?

Hi Dan 
First this feature is not working on RHOS10 and move to RHOS12.
Once this feature will be applicable Cinder need to be deployed by director on the overcloud and add the option to be configure as optional backend to Glance. Maybe the bug need to be refer to triple O team to develop such ability and then document it?

Comment 3 Dan Macpherson 2017-07-31 06:23:29 UTC

So for OSP12, cinder can be installed on the undercloud using the enable_cinder parameter in undercloud.conf.

However, from what I can see, it looks like glance is still using swift for default_store (configured via Puppet) and it looks like the only way to change it is through manual configuration. However, these changes can get overwritten on subsequent puppet runs, so this might not be the best method.

You could try using some hiera overrides in undercloud.conf, but because setting "glance_store/default_store" to "swift" is hardcoded in the swift backend class in the glance Puppet module, I'm not sure what will occur if you also try to set hieradata to configure this param via the API class in the glance Puppet modules  (Will it cause a race condition? Will there be an error?).

Avi, can you provide any advice on the supported way of enabling this feature on OSP12 director?

Comment 4 Lucy Bopf 2018-04-20 04:57:43 UTC

Closing this as insufficient data. It is unclear whether this use case is supported. Please reopen if you can provide a supported and QE-tested way to enable this feature on RHOSP 12 director.
