Description of problem:


Version-Release number of selected component (if applicable):
server,
glusterfs-3.4.0.44rhs-1

client,
glusterfs-3.3.0.7rhs-1

How reproducible:
always, if the client bits are 3.3.0.7rhs-1


Steps to Reproduce:
1. create a volume, start it
2. quota enable, set some limit on the root of the volume.
3. on client with 3.3.0.7rhs-1, mount the volume via glusterfs.
4. df -h on client

Actual results:
step2, result,
[root@nfs1 ~]# gluster volume quota dist-rep12 list

                      300G  256G   45G  86% /mnt/nfs-test


Issue:- as can be see "/mnt/glusterfs-test" displaying 1.8T and 1.5T as Size and Used field respectively. 

Whereas the nfs mount behaves properly.

Expected results:
quota stats should be same for nfs and glusterfs mount.
