I'm new to gluster, so let me try to explain and sorry for my dump question.

If I have a replica made with:

(s1b1, s2b1, s3b1)
(s1b2, s2b2, s3b2)
(s1b3, s2b3, s3b3)

Why I cant add a new server getting this result:

(s1b1, s2b1, s3b1, s4b1)
(s1b2, s2b2, s3b2, s4b2)
(s1b3, s2b3, s3b3, s4b3)

?? In this case , I've added a new server with 3 bricks.
