There is the delete_on_termination option for attaching volume when creating a server but not for an existing server

[Lee Li]

There is the delete_on_termination option for attaching volume when creating a server but not for an existing server. So when delete the server may be two cases although the delete_on_termination option is true, one the attached volume can be deleted, the other is not.

Attach a volume when creating a server, the API contains 'block_device_mapping', such as:
"block_device_mapping": [
            {
                "volume_id": "<VOLUME_ID>",
                "device_name": "/dev/vdc",
                "delete_on_termination": "true"
            }
]

It can contain 'delete_on_termination' option.

But attach a volume to existing server, there is no option 'delete_on_termination', the POST data likes:
{
    "volumeAttachment":{
    "volumeId":"<VOLUME_ID>",
    "device":"/dev/sdb"
    }
}

I've heard of other users wanting similar options. Also, the ability to modify the delete_on_termination field after the instance is created. But this isn't a bug, it would be a feature and therefore need to follow the process at https://wiki.openstack.org/wiki/Blueprints#Nova.

This wishlist bug has been open a year without any activity. I'm going to move it to "Opinion / Wishlist", which is an easily-obtainable queue of older requests that have come on.
