[Nagiosplug-help] Problems with check_disk

[Jens Link]

Hi,

I just ran across a small problem with th check_disk plugin running on
Debian/testing. I can verify this on a second system also running
Debian/testing. Running the same plugin on Debian/stable works fine. I
used the Debian package as well as a self compiled version fresh from
the tar ball.

,----
| root:~/nagios-plugins-1.4.5/plugins# ./check_disk -V
| check_disk (nagios-plugins 1.4.5) 1.79
`----

When I run check_disk against / (/dev/sda5 in the example) I get some
strange results:

,----
| root:~/nagios-plugins-1.4.5/plugins# ./check_disk -w 10 -c 20 -p \
|       /dev/hda5 DISK CRITICAL - free space: /dev 9 MB (99% inode=98%);| \
                                              ^^^^
|       /dev=0MB;0;-10;0;10 
`----

It works fine when I use the mount point or another device:

,----
| root:~/nagios-plugins-1.4.5/plugins# ./check_disk -w 10 -c 20 -p / \
| DISK OK - free space: / 11652 MB (72% inode=92%);| \
| /=4383MB;16883;16873;0;16893
|
| root@:~/nagios-plugins-1.4.5/plugins# ./check_disk -w 10 -c 20 -p \
|       /dev/hda7 DISK OK - free space: /home 20681 MB (22% inode=96%);| \
|       /home=72268MB;93893;93883;0;93903
`----

Here's the disk layout. Mabye it has something to to with udev?

,----
| root:~/nagios-plugins-1.4.5/plugins# df -h
| Filesystem            Size  Used Avail Use% Mounted on
| /dev/hda5              17G  4.3G   12G  28% /
| udev                   10M   72K   10M   1% /dev
| devshm                506M     0  506M   0% /dev/shm
| /dev/hda7              92G   71G   21G  78% /home

cheers,

Jens
