Description of problem:

When on the SMB mount point (Windows client) , rename operation was being performed on files, "remove-brick commit" operation caused failure for the rename operation.

The rename operations were done using Cygwin (application) in Windows7 client

e.g: mv old-file new-file, operation failed with below error

 for i in {2..1000}; do mv $file 2_${i}.docx; file="2_${i}.docx"; done
mv: cannot move ‘2_529.docx’ to a subdirectory of itself, ‘2_530.docx’
 


Version-Release number of selected component (if applicable):
samba-3.6.9-169.1.el6rhs.x86_64
glusterfs-server-3.6.0.28-1.el6rhs.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Create a DHT volume, mount it on windows client, create ms office files on it
2. Perform add-brick and rebalance
3. Rename files in a loop. 
4. Perform remove-brick i.e. remove-brick start, status and once file migration is completed , perform remove-brick commit

Actual results:

Rename operation failed

Expected results:

Rename should not fail
