As of now cinder driver of glance_store generates location url using 'cinder://' prefix only. If user configured multiple stores for cinder then it is difficult to analyse the image is stored in which of the cinder store as the location url for the image is 'cinder://<image_id>'. In order to make cinder driver compatible with multiple stores, Glance needs to change the way of generating the location url and append something unique id to the URL so that it is easier to understand which image is stored in which cinder backend.
This RFE is not considered as a 17.0GA must have, removing the target milestone. Will reset it to 17.1 target when the BZ flag is available.
Doc tracker in JIRA: https://issues.redhat.com/browse/RHOSPDOC-815
Removing Target Milestone. This RFE is related to DCN with non Ceph storage at the edge. Since there is no third party backends supported at the edge yet and low customer's demands, this RFE is being deprioritised.
