$ nova volume-attach $instance_ID $volumes_ID /dev/vdb

/Dev/vdb: the device that is mounted to the instance. To use this space, you need to partition and format it and then mount it.

Tip: Set automatic mounting upon startup!

Transfer (transfer) Volumes

The Administrator creates a transfer-volume, which can be used by other users;

Transfer-volume is implemented by using commands such as cinder transfer *. The admin contributes a large volume of volume and then authorizes the volume through created_id and key_id;

Create a volume transfer request (request)

First, check which volume is provided by an admin;

$ cinder list
$ cinder transfer-create $volume_id

You can append this option to add the name-display_name mytrvolume.
