Cannot create volume from image using Fog

[J Ro]

Hi,

When I use cinder to create a volume from an image, it works.  Here is the debug HTTP request:

DEBUG:keystoneclient.session:REQ: curl -i -X POST http://XXX:8776/v1/96b7fa2fb01c47bb884a1f97e091b8a0/volumes -H "User-Agent: python-cinderclient" -H "Content-Type: application/json" -H "Accept: application/json" -H "X-Auth-Token: TOKEN_REDACTED" -d '{"volume": {"status": "creating", "availability_zone": null, "source_volid": null, "display_description": null, "snapshot_id": null, "user_id": null, "size": 20, "display_name": "volfromsnap", "imageRef": "da5e5085-db75-4b0b-90fd-c82e887f4a1a", "attach_status": "detached", "volume_type": null, "project_id": null, "metadata": {}}}'

However, when attempting this with fog, the imageRef is not being sent:

Ruby code:

v = volume_service.volumes.create(size: 20, display_name: 'tester123', display_description: 'Fog Testing1', options: {imageRef: 'da5e5085-db75-4b0b-90fd-c82e887f4a1a'})

HTTP Request:

POST /v1/c297330967f242549e184e648d657e6f/volumes HTTP/1.1

{"volume":{"display_name":"tester123","display_description":"Fog Testing1","size":20}}

From https://github.com/fog/fog/blob/master/lib/fog/openstack/requests/volume/create_volume.rb, it looks like these options should be parsed, but they are not being sent by the client.  Any ideas?

Thanks!

Hey, I don't have the most experience with the openstack side of things myself. Could you create an issue with this info on github? From there I can usually summon somebody with more direct experience to help out.

Thanks!

Hi J,

  This code calls the model volume.create which takes attributes. So you should call it like so:

v = volume_service.volumes.create(size: 20, display_name: 'tester123', display_description: 'Fog Testing1', imageRef: 'da5e5085-db75-4b0b-90fd-c82e887f4a1a')

Just from the top of my head, so I might be incorrect. Let me know.

Thanks,

That did the trick - thanks!

I am running into a similar problem, and Rupak's solution below does not work for me. I've also tried using the create_volume method with no luck. Here's a snippet from an irb session:

 v = service.create_volume('test volume','A testing volume crete with fog', 200, options={imageRef:'851ebad1-4cfe-468f-94a7-08dfc6b2d29d'})

An empty volume gets correctly created, so I assume I am doing something wrong with passing the imageRef, but every permutation I've tried that makes any sense at all gives me the same result or worse.

Thanks!
