Dear all,

I have researched a little more. I have compared the check_disk from the 
following versions:

    * 1.4.0
    * 1.4.3
    * 1.4.4
    * head from today

Therefore, I have writte the following script:

echo
df -h
echo
echo 1.40:
./check_disk.140 -u GB -w 20% -c 10% -p "/dev/hdc1"
echo 1.43:
./check_disk.143 -u GB -w 20% -c 10% -p "/dev/hdc1"
echo 1.44:
./check_disk.144 -u GB -w 20% -c 10% -p "/dev/hdc1"
echo head:
./check_disk.head -u GB -w 20% -c 10% -p "/dev/hdc1"
echo
echo 1.40:
./check_disk.140 -u GB -w 20% -c 10% -p "/dev/hda3"
echo 1.43:
./check_disk.143 -u GB -w 20% -c 10% -p "/dev/hda3"
echo 1.44:
./check_disk.144 -u GB -w 20% -c 10% -p "/dev/hda3"
echo head:
./check_disk.head -u GB -w 20% -c 10% -p "/dev/hda3"
echo


The output of the script is as follows:

sauron:/usr/lib/nagios/plugins# ./check_disk.test

head:

/storage/media/video=107GB;190;214;0;238

1.40:

1.43:

1.44:
DISK OK - free space: */dev 0 GB* (99% inode=98%);| */dev=0GB*;0;0;0;0
head:
DISK OK - free space: */dev 0 GB* (99% inode=98%);| */dev=0GB*;0;0;0;0

I have marked the part, which seems to be a liitle "strange".

Current Situation, none of the check_disk commands shows the correct 
status info in the web interface...

Any ideas, how to debug/analyse further?

Thanks in advance,
Joerg
