We have a use case to download the volume snapshot and we are using openstack havana version. We can see only nova commands to create the image/server snapshot and glance commands to download the Image/server snapshot. however, we do not see anything similar in Cinder that gives the ability to download the volume snapshot?

Are there any plans to support volume snapshot download in cinder?

When you create a snapshot it is created by cinder and then uploaded to glance. You can download the snapshot from glance with the glance based commands:


The command you are looking for is image download:

image-download Download a specific image.


glance image-download --file snapshot.raw f30b204e-1ce6-40e7-b8d9-b353d4d84e7d

More helpful information about how to get the UUID and download:

Thank you for a quick response. i am afraid this answers my questions, may be i had to phrase it a little differently (I have edited my question).

Well, I wish to download a volume not just a glance image

Vinode or mpetason,

I am also looking to do the same. I have created a snapshot of a Volume, and I wish to download the snapshot and upload it to another region. Have you guys found a way to do that or is there another way to transfer 'snapshots of a volume' between regions.

Thanks, Murtaza

Agree that the solution provided doesn't seem to work (using Juno). I can get a list of volume snapshots using nova volume-snapshot-list. However, those don't appear in the output of glance image-list and glance image-download with either the snapshot's name or UUID fails.
