Comment 1 Raghavendra G 2012-03-20 04:48:53 UTC 
Did you set the limit on a directory already containing data? If it is so, this is not a bug, since quota is enforced only for operations done after a limit is set. If not, please provide exact test cases.

regards,
Raghavendra.

Sorry, I misread the bug. But anyways, answers to the questions asked are welcome.

CHANGE: http://review.gluster.com/3102 (features/quota: don't adjust statfs buffer if size used is already greater than available limit.) merged in master by Vijay Bellur (vijay)
Comment 6 Saurabh 2012-05-24 09:18:15 UTC 
negative values are not seen anymore
