Description of problem:
========================
On a distribute-replicate volume running dbench on cifs mount continuously reports : "[2137] datasync directory "./clients/client7/~dmtmp/PARADOX" failed: Invalid argument"

Version-Release number of selected component (if applicable):
==============================================================
glusterfs 3.4.0.31rhs built on Sep  5 2013 08:23:16

How reproducible:
==================
Often

Steps to Reproduce:
========================
1.Create a distribute-replicate volume (2 x 2). Start the volume. 

2.Create cifs mount.

3.From cifs mount execute: "dbench -s -F -S --one-byte-write-fix --stat-check 10"

Expected results:
===================
dbench shouldn't fail. 

Additional info:
================
The same case works fine on fuse and nfs mount.
