Can't fully disable disk quotas

[vgv]

Hello. I'm trying to disable disk quotas on my server. I've tried with quotaoff -a, then removing the usrquota on /etc/fstab and remounting /home, but the system still doesn't allow to write on an account over quota (can't upload by ftp and log says "Disk quota exceeded" when receiving mail from this account). Any idea?

My fstab looks like:

/dev/md1    /   ext3    errors=remount-ro       0       1
/dev/md2    /home   ext3        defaults        1       2
/dev/sda3   swap    swap        defaults        0       0
/dev/sdb3   swap    swap        defaults        0       0
/dev/devpts             /dev/pts                devpts  gid=5,mode=620  0 0
/dev/shm                /dev/shm                tmpfs   defaults        0 0
/dev/proc               /proc                   proc    defaults        0 0
/dev/sys                /sys                    sysfs   defaults        0 0
/usr/tmpDSK             /tmp                    ext3    defaults,noauto        0 0
/tmp             /var/tmp                    ext3    defaults,bind,noauto        0 0

and my /etc/mtab:

/dev/md1 / ext3 rw,errors=remount-ro 0 0
/dev/proc /proc proc rw 0 0
/dev/sys /sys sysfs rw 0 0
/dev/devpts /dev/pts devpts rw,gid=5,mode=620 0 0
/dev/md2 /home ext3 rw 0 0
/dev/shm /dev/shm tmpfs rw 0 0
none /proc/sys/fs/binfmt_misc binfmt_misc rw 0 0
/usr/tmpDSK /tmp ext3 rw,noexec,nosuid,loop=/dev/loop0 0 0
/tmp /var/tmp none rw,bind 0 0
