changing of the volume types after volume is created.
with this patch, one can do all the below operations:
on a simple distribute volume 'test' with bricks A,B, add bricks C and D:
bash# gluster volume add-brick test replica 2 C D
now the volume 'test' becomes distribute-replicate, with pairs A-C, B-D.
same holds good for stripe.
and now, one can change the replica count 2 on volume 'test' to 4 like below:
bash# gluster volume add-brick test replica 4 E F G H
now, volume has 'replica' count 4, with pairs being 'A-C-E-F' and 'B-D-G-H'.
after this, if user wants to reduce the replica count, he can do
bash# gluster volume remove-brick test replica 3 C H # (one from each pair)
This should work to reduce the replica count
