[Nagiosplug-help] Not showing correct disk space status

[vathakar at banasdairy.coop]

Hi all,

I am running Red Hat 9.0. I have 2 hard disk (SCSI) with RAID Partitions
(md1-/boot, md2-/var, md3-/usr, md4-/). And I am not able to check it's
disk space correctly.

In all partition, it is showing me
     99% free on /dev/hda2
and  98% free on /dev/hda3


But above figure is not correct?

What is the  error?

From,
Vishal...
