What is Volume?
Volumes in OpenStack are a way you can have extra storage for your instances. Volumes are block storage devices that you attach to instances to enable persistent storage. You can attach a volume to a running instance or detach a volume and attach it to another instance at any time. You can also create a snapshot from or delete a volume. Only admin users can create volume types.
