Description Saurabh 2013-08-08 09:45:29 UTC 
Description of problem:
This kind of bug was already filed as 981553, I see that issue is not seen for fuse mount
still I can see the problem over nfs mount.

getting I/O error over nfs mount.

Version-Release number of selected component (if applicable):
[root@nfs1 ~]# rpm -qa | grep glusterfs
glusterfs-api-3.4.0.17rhs-1.el6rhs.x86_64
glusterfs-3.4.0.17rhs-1.el6rhs.x86_64
glusterfs-geo-replication-3.4.0.17rhs-1.el6rhs.x86_64

glusterfs-server-3.4.0.17rhs-1.el6rhs.x86_64
glusterfs-rdma-3.4.0.17rhs-1.el6rhs.x86_64

How reproducible:
happened on this build also.

Steps to Reproduce:
1. create a volume as 6x2, start it.
2. enable quota on the volume
3. put a limit of 2GB
4. mount the volume nfs
5. create a directory inside the volume
6. put a limit of 1GB on the directory
7. start creating data inside the dir
