Hi Vijay,

I was recreate the issue. 
1) Create a replicated volume with 2 CentOS 6.5 machines 

i)gluster volume create homedir replica 2 transport tcp node1:/brick1/homedir node2:/brick1/homedir


gluster  volume set homedir network.ping-timeout 10

gluster  volume set homedir performance.cache-size 1GB

gluster  volume set homedir nfs.rpc-auth-allow 10.99.30.20,10.99.30.21

gluster  volume set homedir auth.allow 10.99.30.20,10.99.30.21

gluster  volume set homedir features.quota on

gluster  volume set homedir features.quota-timeout 0

gluster  volume set homedir features.quota-deem-statfs on


ii) setup quotas on around 900 folders


node1:~# gluster volume quota homedirlist |wc -l

903


iii) Created a rsync to create/delete files with different names  in 20 different folders and ran every 2 minutes

iv) in Around 2 days some directories showed PB in files used

Hi Omar,

If the issue is happening consistently, can we get a re-creatable test-case for this same?

Thanks,
Vijay

Hi Guys,

I am using gluster 3.5.2 and for couple of directories I am getting used space as 16384.0 PB

 node1:~# gluster volume quota homedir list |grep PB

/storage/home1                          3.0GB       90%   16384.0PB   3.0GB

/storage/home2                             1.0GB       90%   16384.0PB   1.0GB



DU on actual directory


node1:~#  du -hs /data/storage/home1/

368K    /data/storage/home1/


node1:~#  du -hs /data/storage/home2

546K    /data/storage/home2


I am using replicated volume (replica count 2) and mounted volume as nfs. Individual bricks are formatted as ext4. If I remove quotas and restart replicated volume and then re-add quotas then gluster quota shows correct value (instead of 16384.0 PB) but once file transfer starts and files are added/deleted again these directories start showing incorrect values. 


Just wanted to check if this is a bug in gluster quota and/or if there is any way to mitigate this?



I do see a similar bug but for 3.4

Thanks
