[Nagiosplug-help] check_disk DISK UNKNOWN Problem

[Steffen Knauf]

Hello,

i use check_by_ssh to execute check_disk on the remote machine.

Remote Client: (64 Bit) Linux version 2.6.16.21-0.8-smp 
(geeko at buildhost) (gcc version 4.1.0 (SUSE Linux))
Nagios Server (32 Bit): Linux version 2.6.16.21-0.8-bigsmp 
(geeko at buildhost) (gcc version 4.1.0 (SUSE Linux))

I get the same error, if i try it directly on the remote client

local command:
"/usr/local/nagios/libexec/check_disk -w 10% -c 5% -u MB  -p 
/serverdisks/raid4p3"

Error Message:
DISK UNKNOWN - free space:|

check_disk Version:
check_disk v1848 (nagios-plugins 1.4.11)

The partition is very tall (nearly 7 TB).   With two other partitions (4 
TB and 3 TB), i don't get any errors.
Is there a limit for the partition size? Any Ideas?

greets

Steffen
