Need help with full space problem

[hukaru]

Initially I have a problem with no free space left.
I can't log in to DA page.
So I use ssh and clear it out then I get space back about 300MB. (by df -h command)
The server is back to normal.
After 10 min I got same problem again.
Then I tried to free up some space and I got back around 4GB.
But I still can't log in to DA

df -h shows

[root@bit01 admin]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/Volume00-LogVol01     72G   68G     0 100% /
/dev/sda2              76M   13M   61M  17% /boot
none                  1.5G     0  1.5G   0% /dev/shm

Available space is not sync with Size/Used space
Then I try

tail /var/log/directadmin/error.log. Make sure the disk isn't full.<br>

Look like directadmin still know that no free space left.
Anybody have an idea how to fix it.

Thanks.

Solved

The problem was solved by running

tune2fs -l /dev/mapper/Volume00-LogVol01

And I can see there are some reserved block.
So I clear it out with

tune2fs -m 0 /dev/mapper/Volume00-LogVol01

Then df shows correctly available space.
