Q u o a t a s doesn't work

Red hat 8.0
Trying to activate disk quotas for user. I´ve read the Quota mini-HOWTO, but I can't make it work.

I assume the prekompiled kernel supports quotas, is that correct? The quota tools are on the system.

My fstab looks like this:
LABEL=/                 /                       ext3    defaults        1 1
LABEL=/boot             /boot                   ext3    defaults 1 2
none                    /dev/pts                devpts  gid=5,mode=620  0 0
LABEL=/home             /home                   ext3    defaults,usrquota 1 2
...

and there is this part in the /etc/rc.sysinit

# check remaining quotas other than root
if [ X"$_RUN_QUOTACHECK" = X1 -a -x /sbin/quotacheck ]; then
        action $"Checking local filesystem quotas: " /sbin/quotacheck -aRnug
fi
if [ -x /sbin/quotaon ]; then
    action $"Enabling local filesystem quotas: " /sbin/quotaon -aug
fi

Hower, I get this in boot.log
  Cannot find quota file on /home [/dev/hda5] to turn quotas on/off.

So I try to do
  edquota -u user
And get this
  edquota: Quota file not found or has wrong format.
  No filesystems with quota detected.

What is missing?

Thanks for your time,
