Topic: MRTG 2. harddisk help

[trenskow]

Hi there all

I have installed the MRTG from http://sme-swerts.knudsen.dk and is having a problem with my 2. harddisk.
I have the harddisk installed on /dev/hdb, and uses it as backup. Now, my problem is, that i get this error from Cron Daemon.
"SNMP Error:

i tried updating the mrtg, and now the error is slightly different

SNMP Error:

and now there is a second error

ERROR: It looks as if you are running two copies of mrtg in parallel on
       the same config file. There is a lockfile (/etc/mrtg/mrtg.cfg_l) and it is
       is only 0 seconds old ... Check your crontab.

i have an idea what is wrong, but i dont know how to fix it.
