/data/mounts/mount was mounted before quota limit was set, & after setting the limit , df does not show updated limit.

Comment 2 Amar Tumballi 2013-02-04 11:25:53 UTC

df (ie, statvfs()) call is for the mounted filesystem, while quota is for a volume, which would have directory quota enabled, thus, its not fair to make df behave differently depending on the quota value.

df should always not bother about quota, and quota limits should be fetched by different quota command (in our case 'gluster quota limit-usage ').
