Marking this as invalid, as I think this is the correct behaviour. There was talk of adding the ability to resize a volume during resize using BDM, but thats a spec.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1412993 Title: Nova resize for boot-from-volume instance does not resize volume Status in OpenStack Compute (nova): Invalid Bug description: Resizing an instance which booted from a volume to a new flavor with a bigger disk will not cause the volume to resize accordingly. This can cause confusion among the users, which will expect to have instances with bigger storage. Scenario: 1. Have a glance image. 2. Create a bootable volume from glance image. 3. Create instance using volume and flavor having 10GB disk. 4. Perform nova resize on instance to a new flavor having 20GB disk. 5. After resize, see that the instance still has 10GB storage. Cinder volume still has the same size. This issue has been discussed on #openstack-nova and it was agreed upon to fail the resize operation, if the given instance is booted from volume and the given new flavor has a different disk size.
