I was using a standard OpenStack version from Debian official repository.

This is how I was creating the volume:

# cinder create --image-id 1b84776e-25a0-441e-a74f-dc5d3bf5c103 5

The volume is created instantly.

# rbd info volume-abca46dc-0a69-43f0-b91a-412dbf30810f -p cinder_volumes
rbd image 'volume-abca46dc-0a69-43f0-b91a-412dbf30810f':
        size 5120 MB in 640 objects
        order 23 (8192 kB objects)
        block_name_prefix: rbd_data.301adaa4c2e28e
        format: 2
        features: layering
        parent: glance_images/1b84776e-25a0-441e-a74f-dc5d3bf5c103@snap
        overlap: 4608 MB

Isn't it a copy-on-write clone?
