Detaching a Cloud Block Storage (CBS) Volume will prevent you from writing to it when you want to take a Snapshot. It is also useful when you want to take a Volume offline for storage purposes, or to move a Volume to another Server. Lastly, you should detach a Volume before you delete it. In all cases, you must unmount the Volume before you detach it through the Control Panel. The instructions are below.
