Description of problem:

I tried to remove 3 bricks from "2 x 3" (with arbiter) and no data was rebalanced.


Version-Release number of selected component (if applicable):

glusterfs 3.7.2 built on Jun 23 2015 12:13:13

How reproducible:

Create replica 2 x 3 with arbiter and then remove 3 bricks


Steps to Reproduce:
1. gluster volume create replica_name replica 3 arbiter 1 host:/mnt/brick/1 host:/mnt/brick/2 host:/mnt/brick/3 host:/mnt/brick/4 host:/mnt/brick/5 host:/mnt/brick/6 force
2. add some data
3. gluster volume remove-brick replica_name host:/mnt/brick/4 host:/mnt/brick/5 host:/mnt/brick/6 start
4. gluster volume remove-brick replica5 host:/mnt/brick/4 host:/mnt/brick/5 host:/mnt/brick/6 status

Actual results:

- rebalancing of all files failed

Node Rebalanced-files          size       scanned      failures       skipped               status   run time in secs

Expected results:

All files should be re-balanced and I should be able to remove the bricks from the volume.
