CHANGE: http://review.gluster.com/304 (without which, quota would get confused about the total size) merged in master by Vijay Bellur (vijay)

Comment 4 Saurabh 2011-10-20 10:03:26 UTC

finding similar kind of problem on 3.2.5qa2,

concern is that the data is moved from one directory to other directory over nfs mount.

Note:- just before this test I had tried replace-brick test, though quota calculation was correct after that test.

Comment 5 Richard 2013-01-23 21:18:15 UTC

This seems to work for me in 3.3.1-8.fc18

Comment 6 Amar Tumballi 2013-02-04 09:24:45 UTC

as per comment #5, and also, please test quota in scale of GBs and keep ~1-3% offset for errors considering its distributed quota implementation, and is hard to achieve.
