  - ### DiskBalancerException

    public DiskBalancerException(String message, DiskBalancerException.Result result)
    Constructs an `IOException` with the specified detail message.
    Parameters:
      `message` - The detail message (which is saved for later retrieval by the `Throwable.getMessage()` method)

  - ### DiskBalancerException

    public DiskBalancerException(String message, Throwable cause, DiskBalancerException.Result result)
    Constructs an `IOException` with the specified detail message and cause.

    Note that the detail message associated with `cause` is not automatically incorporated into this exception's detail message.

    Parameters:
      `message` - The detail message (which is saved for later retrieval by the `Throwable.getMessage()` method)
      `cause` - The cause (which is saved for later retrieval by the `Throwable.getCause()` method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

  - ### DiskBalancerException

    public DiskBalancerException(Throwable cause, DiskBalancerException.Result result)
    Constructs an `IOException` with the specified cause and a detail message of `(cause==null ? null : cause.toString())` (which typically contains the class and detail message of `cause`). This constructor is useful for IO exceptions that are little more than wrappers for other throwables.
    Parameters:
      `cause` - The cause (which is saved for later retrieval by the `Throwable.getCause()` method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
