Title:
Glance V2 API is not backwards compatible and breaks Cinder solidfire
driver
Status in Cinder:
Won't Fix
Status in Glance:

Status in puppet-cinder:
Won't Fix
Bug description:
In stable/kilo
Glance API V2 change of image-metadata is_public flag to visibility =
Public breaks the SolidFire (and maybe other, NetApp?) drivers that
depend on is_public flag. Specifically this breaks the ability
efficiently handle images by caching images in the SolidFire cluster.
Changing the API back to V1 through the cinder.conf file then breaks
Ceph which depends on V2 and the image-metadata direct_url and
locations to determine if it can clone a image to a volume. So this
breaks Ceph's ability to efficiently handle images
This version mismatch does not allow for SolidFire and Ceph to both be
used efficiently in the same OpenStack cloud.
NOTE: openstack/puppet-cinder defaults to glance-api-version = 2 which
allows Ceph efficientcy to work and not SolidFire (and others).
Mainly Opening this Bug to document this problem since no changes are
allowed to Kilo there is probably no way to fix this.
