Description Pranali Deore 2018-07-06 09:45:23 UTC

Description of problem:

Glance adding the support of Multi store which opens the door to a handful of image replication and backend targeting use cases which can provide additional value related to fault tolerance, image locality and policy based image hosting.

To enable multi store support, glance has introduced 'enable_backends' parameter which will have list of enabled stores identified by their property group name. And according to the stores defined in 'enabled_backends', we need to add a separate section for each store in glance-api.conf as well as need to create new ceph.conf files if ceph backend is there in the backends list.

All these configuration support needs to be added in tripleo & puppet-glance



[Note]: Glance Multi Store Patches are not yet merged

Comment 10 Alan Bishop 2019-10-04 18:47:28 UTC

A patch has been posted to update puppet-glance, which is just the first piece of work required for this RFE. Significant puppet-tripleo and tht patches still need to be developed.

I think we also need to make tripleo call ceph-ansible multiple times to create the ceph config files and keyrings for each cluster

Comment 15 Cyril Roelandt 2020-01-20 20:21:53 UTC

The patch has been merged upstream and seems to be available downstream (it is in remotes/rhos/rhos-16.0-trunk-patches). Should we move this bug to ON_QA or do we need anything else?

Comment 16 Cyril Roelandt 2020-01-20 20:25:04 UTC

And we obviously have an RPM with the fix (branch rhos-16.0-rhel-8-trunk, version 15.4.0-1).

Comment 17 Alan Bishop 2020-01-20 20:52:46 UTC

The puppet-glance patch has merged, but the puppet-tripleo and tht patches are still under development.

Comment 19 Alan Bishop 2020-01-27 17:54:46 UTC

puppet-tripleo and tht patches have been proposed upstream.

Comment 23 Alan Bishop 2020-02-27 14:07:05 UTC

Patches are on master, proposed to stable/train.
