[Openstack] missing volume_image_metadata in Juno Volumes disables snapshots

Hi all,

We're having an issue with snapshots in Juno (cinder version: 2014.2;
1.el7.centos ) with volumes created as "empty volumes".

The issue is that these volumes haven't got the key volume_image_metadata
filled and whenever a snapshot is tried on these volumes, the following
error appear:

MetadataCopyFailure: Failed to copy metadata to volume: Glance metadata for
volume/snapshot

Creating an entry in the database enables the snapshoting and everything
seems to work but I was wondering whether the bug
https://bugs.launchpad.net/cinder/+bug/1378276 is what is affecting this
behaviour or a new bug shall be opened.

Besides, and meanwhile, is there a workaround before the bug is properlly
solved instead of having to manually create an entry in cinder's database?

Thanks a lot for your amazing work,
samuel.
