Comment 3 for bug 1703605

Yes, this is what I'm seeing as well. Also, the cinder attachments will be filtered based on 'attach_status' of both the Volume and VolumeAttachment. In both cases the 'attach_status' must be 'attached' and not 'attaching'. So if the 'stack show' is performed during this time it will cache the empty list as well it seems.

In this case is there a option invalidate the cache without specifying CACHE_NONE on the 'attachments_list' attribute?
