1. Delete following xattrs from all the files/directories on all the bricks
a) trusted.glusterfs.quota.size
b) trusted.glusterfs.quota.*.contri
c) trusted.glusterfs.quota.dirty
2. Turn off md-cache
# gluster volume set <volname> performance.stat-prefetch off
3. Mount glusterfs asking not to use readdirp instead of readdir
# mount -t glusterfs -o use-readdirp=no <volfile-server>:<volfile-id> /mnt/glusterfs
4. Do a crawl on the mountpoint
# find /mnt/glusterfs -exec stat \{} \; > /dev/null
This should correct the accounting on bricks. Once done, you should see correct values in quota list output. Please let us know if it doesn't work for you.

We are working on these bugs. We'll update on the bugzilla once we find anything substantial.
