Hi Ignazio,

The feature was introduced in Pike release [0], so it should work.

Please specify the Volume API version >= 3.40 either by:

a) passing `--os-volume-api-version` parameter to the command line:

cinder --os-volume-api-version 3.40 revert-to-snapshot snap1

b) exporting the environment variable OS_VOLUME_API_VERSION:

export OS_VOLUME_API_VERSION=3.40

cinder revert-to-snapshot snap1

Please let us know if it works or not.

Hello Stackers,
does cinder revert to snapshot works on stein ?
The command cinder revert-to-snapshot returns:

error: argument <subcommand>: invalid choice: u'revert-to-snapshot'

I also tried using cinder v3 api post /v3/{project_id}/volumes/{volume_id}/action
but it returns :
{"itemNotFound": {"message": "The resource could not be found.", "code": 404}}

Please, anyone could help me ?
