[Gluster-users] quota calculation gluster 3.2.3

Hi Anthony,

By volume configuration, I meant 'is the volume setup dht, afr, or dht-afr',
I would like to know the output of

   volume info volume-name

When data is already present before the activation of quota, it takes some
time for quota values to converge because it has to crawl through the entire
file-system to calculate the sizes. This is automatically done when you run

   volume quota vol-name enable

The output of
   volume quota vol-name list

will reflect the aggregated value at that point in time. If the values are
not converging then its a issue. A simple work-around is to run ls -lR on
the mount point. Please confirm if the values were not converging
automatically, we will have a look into it.
