[Nagiosplug-help] [Nagios-users] BUG: check_disk doesn't support LVM volumes

If I specify path, I get the exact same error.

But if you look at the error returned by the plugin - its complaining
about the values of -w and -c - surely its parsing it wrong (possibly
because its being passed back something it doesn't understand?)

It works fine here --

$ cat /etc/redhat-release
CentOS release 3.6 (Final)

$ ./check_disk -V
check_disk (nagios-plugins 1.4.3) 1.64

/dev/Volume00/LogVol01 on /usr type ext3 (rw)

$ ./check_disk -w 10% -c 5% --partition=/dev/Volume00/LogVol01
DISK OK - free space: /usr 7733 MB (79% inode=95%);|

$ ./check_disk -w 10% -c 5% -p /usr
DISK OK - free space: /usr 7733 MB (79% inode=95%);|

Do you see the error if you specify the path instead of the mountpoint?
What OS are you using? Do you have SELinux enabled? If so, see if
SELinux is blocking access.
