module: cloudscale_volume
short_description: Manages volumes on the cloudscale.ch IaaS service.
description:
- Create, attach/detach, update and delete volumes on the cloudscale.ch IaaS service.
notes:
- To create a new volume at least the I(name) and I(size_gb) options
are required.
- A volume can be created and attached to a server in the same task.
