-- Detaches an EBS volume from an instance. Make sure to unmount any file
-- systems on the device within your operating system before detaching the
-- volume. Failure to do so can result in the volume becoming stuck in the
-- @busy@ state while detaching. If this happens, detachment can be delayed
-- indefinitely until you unmount the volume, force detachment, reboot the
-- instance, or all three. If an EBS volume is the root device of an
-- instance, it can\'t be detached while the instance is running. To detach
-- the root volume, stop the instance first.
--
-- When a volume with an Amazon Web Services Marketplace product code is
-- detached from an instance, the product code is no longer associated with
-- the instance.
