3.5.5. Enabling Quota Accounting
It is possible to keep track of disk usage and maintain quota accounting for every user and group without enforcing the limit and warn values. To do this, mount the file system with the quota=account option specified.
In this example, the GFS2 file system on /dev/vg01/lvol0 is mounted on the /mygfs2 directory with quota accounting enabled.
mount -o quota=account /dev/vg01/lvol0 /mygfs2
