Hi Junaid,
Sorry I was not able to reach you on IRC, I just see your email this morning because of the time difference.
I'll try to delete the volume and the backend and start from scratch. I'll keep you in touch.

Hi Anthony,
Previously, you had a volume which was pure replicate and it had the servers
Volume Name: venus
Type: Replicate
Status: Started
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: ylal3020:/soft/venus
Brick2: ylal3030:/soft/venus
and then you created another distributed-replicate volume which used the bricks of previous volume as part of the new volume
Volume Name: venus
Type: Distributed-Replicate
Status: Started
Number of Bricks: 2 x 2 = 4
Transport-type: tcp
Bricks:
Brick1: ylal3020:/soft/venus
Brick2: ylal3030:/soft/venus
Brick3: yval1000:/soft/venus
Brick4: yval1010:/soft/venus
So, what I suspect is the extended attributes were carried forward as part of the of the new volume. So, when a file is created in the new volume, for quota it will the extended attribute value + the new file size. If this is true in your case, then please use fresh backend directories(newly created directories) and kindly report if you see the same behavior.

Hi Anthony,
Are you reachable on #gluster irc, it will be easy to debug this issue on irc. I will be available at gluster irc after 11am IST. I will reply to your mail but it will speedup the debug process if you are on irc.

Hi Junaid,
Sorry about the confusion, indeed I gave you the
wrong output. So let's start to the beginning. I disabled quota and I
reactivated it
My configuration :
Volume Name: venus
Type: Distributed-Replicate
Status: Started
Number of Bricks: 2 x 2 = 4
Transport-type: tcp
Bricks:
Brick1: ylal3020:/soft/venus
Brick2: ylal3030:/soft/venus
Brick3: yval1000:/soft/venus
Brick4: yval1010:/soft/venus
Options Reconfigured:
nfs.port: 2049
performance.cache-refresh-timeout: 60
performance.cache-size: 1GB
network.ping-timeout: 10
features.quota: on
features.limit-usage: /test:100MB,/psa:200MB,/:7GB,/soft:5GB
features.quota-timeout: 120
Size of each folder from the mount point :
/test : 4.1MB
/psa : 160MB
/soft : 1.2GB
Total size 1.4GB
(If you want the complete output of du, don't hesitate)
gluster volume quota venus list
path limit_set size
----------------------------------------------------------------------------------
/psa 200MB 167.0MB <=OK
/soft 5GB 4.7GB <= NO OK
/test 100MB 4.0MB <= OK
/ 7GB 5.2GB <= NO OK
Is seems this is 4 time the original size for / and /soft
