Description of problem:
this is about creating data in a sub-directory.
while the disk quota gets exceeded and file is getting written, the dd command goes for a sleep mode.
and if try to come out of the script using ctrl-c then dd command goes for "D" state.
sometimes I am able to come out of the script and sometimes not. 

Version-Release number of selected component (if applicable):
client,
[root@rhsauto030 dir]# rpm -qa | grep gluster
glusterfs-3.4.0.12rhs.beta3-1.el6rhs.x86_64
glusterfs-fuse-3.4.0.12rhs.beta3-1.el6rhs.x86_64

server,
[root@quota1 ~]# rpm -qa | grep glusterfs
glusterfs-3.4.0.12rhs.beta3-1.el6rhs.x86_64
glusterfs-fuse-3.4.0.12rhs.beta3-1.el6rhs.x86_64
glusterfs-server-3.4.0.12rhs.beta3-1.el6rhs.x86_64


How reproducible:
many times has happened that the dd has gone for "D" state.

Steps to Reproduce:
1. create a volume, start it
2. enable quota
3. set quota on the volume for "30GB"
4. mount the volume using glusterfs
5. create 10 directories namely dir[1-10]
6. create 1 subdirectoy in each of them.
7. set quota limit for all of them, say for directories it is 2GB and for subdirectories it is 100MB
8. create data using below mentined script,

#!/bin/bash
set -x

create-data()
{
while [ 1 ]
do
cmd=`dd if=/dev/urandom of=$(date +%s) bs=1024 count=1024 2>&1`
echo $cmd
if [ "$(echo $cmd | awk '/Disk quota exceeded/')" ] 
then
   echo "quota limit reached"
   break
fi
done
return 1
}

create-data



Actual results:
many times the script does not come out of execution as the dd command has gone for sleep mode, for quite a time.

+++ date +%s

root     26695  0.0  0.0 103248   808 pts/1    S+   10:54   0:00 grep dd


now if I try to use ctrl-c to kill the process, the dd command goes to "D" state.

Expected results:
I percieve if the quota limit is reached, dd command should recieve response like "Disk quota exceeded" rather keep waiting and going to sleep mode.
