Description of problem:
Quota exceeds even with the data less than the quota limit.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. created a distribute volume with 2 bricks
2. set quota of 900MB
3. created a file of size 500MB
4. Create another file of size 400MB but when the second file size if still 270MB, "Disk quota exceeded " message was thrown and dd fails.
5. Further creation of files on the mountpoint is possible.
[root@gqac022 mnt]# dd if=/dev/urandom of=400MB bs=1MB count=400
dd: writing `400MB': Disk quota exceeded
271+0 records in
270+0 records out
270520320 bytes (271 MB) copied, 31.941 s, 8.5 MB/s
[root@gqac022 mnt]# echo "akdsjfkasjfkasjdfksajfkasjf" >> 400MB
