Reproduced the issue twice till now 


Steps to Reproduce:
===================

1.Create a 2x2 dist-replicate volume and start it

2.Mount the volume and give permissions 

mkdir /mnt/sampl/
mount -t glusterfs 10.70.34.85:/sample /mnt/sampl/
chmod 777 /mnt/sampl/

3.Add 2 more bricks to the volume 

4.As non root user (ABC)create some files on the mount point . Few files give "permission denied" error 

[ABC@dhcp-0-180 sampl]$ for i in {1..150} ; do dd if=/dev/urandom of=z"$i" bs=10M count=1; done
dd: opening `z1': Permission denied
