[Gluster-users] Quota list not reflecting disk usage

[Steve Dainard]

This is gluster 3.6.6.

I've attempted to disable and re-enable quota's on the volume, but
when I re-apply the quotas on each directory the same 'Used' value is
present as before.

Where is quotad getting its information from, and how can I clean
up/regenerate that info?
