I have enabled user and group quotas on /home
(long time before i upgrade to redhat 6.1), and
/usr/sbin/warnquota is running daily by crontab script.

Since i have upgraded from redhat 5.2 to 6.1 the
root user gets quota warnings every night via mail,
but root user has no quotas.

Other users dont get any mail if the are in violation
with the quota system.


Here is one warnquota mail:

Subject: Disk Quota usage on system

Hi,

We noticed that you are in violation with the quotasystem
used on this system. We have found the following violations:

                        Block limits               File limits
Filesystem           used    soft    hard  grace    used  soft  hard  grace
/dev/sdd1      --  101344       0       0           3608     0     0


We hope that you will cleanup before your grace period expires.

Basically, this means that the system thinks you are using more disk space
on the above partition(s) than you are allowed.  If you do not delete files
and get below your quota before the grace period expires, the system will
prevent you from creating new files.
