Public Instance methods

Detaches the volume from its instance. @option options [Boolean] :force Forces detachment if the

  previous detachment attempt did not occur cleanly (logging
  into an instance, unmounting the volume, and detaching
  normally). This option can lead to data loss or a
  corrupted file system. Use this option only as a last
  resort to detach a volume from a failed instance. The
  instance will not have an opportunity to flush file system
  caches or file system metadata. If you use this option,
  you must perform file system check and repair procedures.

@return [Boolean] Returns true if the attachment exists.
