Create Volume

A Volume provides storage space that can be used with your Server. This storage space is independent from the storage space that is included with your Server. Once a volume is created, it can be easily attached to a Server. Once attached, it will appear as a mounted device. You can attach multiple volumes to a Server.

POST /volumes

This operation will create a new volume.
