Description of problem:

while the I/O is happening put down the quotad process,
the data creation crosses the set hard limit
the quota list which is suppose to do it's own mount for collecting info about used space and available space,
has given wrong output

[root@nfs1 ~]# gluster volume info
 
Volume Name: dist-rep
Type: Distributed-Replicate
Volume ID: edc23717-011b-42c6-b984-2922dcaeff5d
Status: Started
Number of Bricks: 6 x 2 = 12
Transport-type: tcp

Version-Release number of selected component (if applicable):
[root@nfs1 ~]# rpm -qa | grep glusterfs
glusterfs-3.4.0.12rhs.beta4-1.el6rhs.x86_64
glusterfs-fuse-3.4.0.12rhs.beta4-1.el6rhs.x86_64
glusterfs-server-3.4.0.12rhs.beta4-1.el6rhs.x86_64
[root@nfs1 ~]# 


How reproducible:
tried the test this time

Steps to Reproduce:
1. create volume, start it 
2. enable quota
3. set hard limit of 1GB
4. mount the volume over nfs
5. mkdir mount-point/dir
6. start creating data. Data creation includes 1MB files in a for loop.
7. kill quotad process meanwhile the data creation is happening.


Actual results:
