OK, let's do it again :) ... with ext3 partition.

I copied my home to /var which is an ext3 fs.

# mount|grep sda6
/dev/sda6 on /var type ext3 (rw,usrquota)

# cat /etc/mtab |grep sda6
/dev/sda6 /var ext3 rw,usrquota 0 0

# quotaoff -p /var
group quota on /var (/dev/sda6) is off
user quota on /var (/dev/sda6) is on

# repquota -u /dev/sda6|grep dumitru
