Couple of observations:

  * When expanding distributed replicated and distributed striped
    volumes, you need to add a number of bricks that is a multiple of
    the replica or stripe count. For your add brick command you are not
    providing enough bricks to expand the volume. So it will fail.
  * When you use "stripe 3 replica 2" in the add-brick command to expand
    an existing volume of "stripe 2 replica 2" , the volume type is
    going to change from stripe 2 to 3.
  * If you keep "stripe 2 replica 2" in the add-brick command , you need
    to provide 4 bricks.


Refer the admin guide [1] to know about add-brick etc.
