[Gluster-users] Gluster quota showing wrong space utilization (showing 16384.0 PB)

[Omkar Kulkarni]

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
