In the above bug, error is not reported to client is because if copy-from is used then it starts new async process which downloads the image given in the copy-from option.
Please refer ​https://github.com/openstack/glance/blob/master/glance/api/v1/images.py#L756

As the size of the image is unknown when the --copy-from option is specified its not possible to calculate quota is sufficient or not.

One solution for this is can we make size mandatory for --copy-from option which will help to calculate quota before triggering the download.

Please suggest.
