I am using a distribute-replicate volume and trying to replace a brick
details are here,
gluster> volume info repdist

Volume Name: repdist
Type: Distributed-Replicate
Status: Started
Number of Bricks: 3 x 2 = 6
Transport-type: tcp
Bricks:
Brick1: domU-12-31-39-10-76-40.compute-1.internal:/mnt/repdist
Brick2: domU-12-31-39-0A-31-D2.compute-1.internal:/mnt/repdist
Brick3: domU-12-31-39-00-C9-C2.compute-1.internal:/mnt/repdist1
Brick4: domU-12-31-39-16-F9-F5.compute-1.internal:/mnt/repdist1
Brick5: domU-12-31-39-10-76-40.compute-1.internal:/mnt/repdistadd
Brick6: domU-12-31-39-10-76-40.compute-1.internal:/mnt/repdistadd2

effectively replace-brick does not happen.

Saurabh,

You have to do 'replace-brick .... commit' before that new configuration taking effect. Please re-open this bug if you see if its not happening after you do the commit also.
