--- Comment #4 from Neil Van Lysel <nvanlysel at morgridge.org> ---
Hi Manikandan,

I enabled quotas on the volume again and set the "quota-deem-statfs" to "on".
The quota counts are no longer being double counted, instead they're just
completely incorrect:

[root at storage-1 ~]# gluster volume quota home list
                  Path                   Hard-limit Soft-limit   Used 
Available
--------------------------------------------------------------------------------
/test                                     50.0TB       80%       4.6TB  45.4TB

[root at client-1 ~]$ df -h /home/test
Filesystem                        Size  Used Avail Use% Mounted on
storage-1:home                    50T   24T   27T  47% /home

[root at client-1 ~]$ du -sh /home/test
110G    /home/test


Also, I'm seeing the following messages over and over in the brick logs on the
Gluster servers:
