[Gluster-users] Quota list not reflecting disk usage

[Steve Dainard]

I have a distributed volume with quota's enabled:

Volume Name: storage
Type: Distribute
Volume ID: 26d355cb-c486-481f-ac16-e25390e73775
Status: Started
Number of Bricks: 4
Transport-type: tcp
Bricks:
Brick1: 10.0.231.50:/mnt/raid6-storage/storage
Brick2: 10.0.231.51:/mnt/raid6-storage/storage
Brick3: 10.0.231.52:/mnt/raid6-storage/storage
Brick4: 10.0.231.53:/mnt/raid6-storage/storage
Options Reconfigured:
performance.cache-size: 1GB
performance.readdir-ahead: on
features.quota: on
diagnostics.brick-log-level: WARNING

Here is a partial list of quotas:
# /usr/sbin/gluster volume quota storage list
                  Path                   Hard-limit Soft-limit   Used
Available  Soft-limit exceeded? Hard-limit exceeded?
---------------------------------------------------------------------------------------------------------------------------
...
/projects-CanSISE                         10.0TB       80%      11.9TB
 0Bytes             Yes                  Yes
...

If I du on that location I do not get 11.9TB of space used (fuse mount point):
[root at storage projects-CanSISE]# du -hs
9.5T .

Can someone provide an explanation for how the quota mechanism tracks
disk usage? How often does the quota mechanism check its accuracy? And
how could it get so far off?

Can I get gluster to rescan that location and update the quota usage?

Thanks,
Steve
