Bug 801357

Description of problem:

I have put up some limit for quota and created some files, after changing the limit to a higher value still the data creation fails with "Disk quota exceeded" 

presently seen only with nfs.



Version-Release number of selected component (if applicable):
3.3.0qa26

How reproducible:
always

Steps to Reproduce:
1. create a distribute-replicate volume 
2. set the limit for quota to 1MB
3. create files on the nfs mount upto the limit crosses.
4. now change the limit to a higher value lets say, 250GB or 1GB
5. now try to create the files over nfs mount
  
Actual results:
the new addition of data is unsuccessful.


Expected results:
addition of data should be successful
