1 - Purpose

  • an alternative way to check your Coraid Device

  • allow you to check : disks and raid state, if you still have spare disk

  and so on...

  ( programs instead of Java

2 - Installation

First you have to install expect

    $ sudo apt-get install expect (adapt this command line to your distrib)

and cec

    just download the source and run the make command

3 - Content : the main script. You will have to run only this


    expect_scripts : this folder contains all the scripts which retrieve

          informations from the Coraid device.

          You never have to touch to this folder and its contain

4 - Howto use

First you have to edit the following variables of

(Path variables) and adapt it to your configuration :

    statedir : path to save expect scripts outputs

    cec : path to cec program

    expect : path to expect program

    expect_script : path to expect_scripts folder

Add the following entry to your sudoers file to have the good privileges to run

the script :

    nagios ALL=(ALL) NOPASSWD: //

Then just run this command line to display help :

    $ sudo // -h

5 - Examples of use

  • To show all disks UP with extra information for the shelf 0 on the bond0


$ sudo // -s 0 -a show -i bond0 -m

CHECK CORAID - show - OK - (0.0,1000.205GB) (0.1,1000.205GB) (0.2,1000.205GB) (0.14,1000.205GB) are detected as UP - 4 disks UP

  • To show all spare disks with extra information for the shelf 0 on the

  bond0 interface

$ sudo // -s 0 -a spare -i bond0 -m

CHECK CORAID - spare - OK - (0.10,1000.205.GB) (0.11,1000.205GB) detected as SPARE - 2 disk(s) as SPARE

6 - Examples of NRPE integration

NRPE server configuration (typically /etc/nagios/nrpe_local.cfg) :

command[check_coraid_spare]=/usr/bin/sudo /usr/local/nagios/libexec/ -s 1 -i bond0 -p -a spare

command[check_coraid_raid]=/usr/bin/sudo /usr/local/nagios/libexec/ -s 1 -i bond0 -p -a raid

command[check_coraid_show]=/usr/bin/sudo /usr/local/nagios/libexec/ -s 1 -i bond0 -p -a show

command[check_coraid_when]=/usr/bin/sudo /usr/local/nagios/libexec/ -s 1 -i bond0 -p -a when

Don't forget to restart the nrpe daemon :

$ sudo /etc/init.d/nagios-nrpe-server restart

From your monitoring node, you only have to call the script just like this :

$ //check_nrpe -H $host_ip -c check_coraid_spare

May be you have to specify a timeout value, in this case call the script like this :

$ //check_nrpe -H $host_ip -c check_coraid_spare -t 15


7- Info

May be you have to adapt the except script to your config

  • may be you have to change the cec prompt start (depends ofyour coraid firmware

  • in the same way the escape character could be different but according to the cec manpage with the -e option you can specify which character you will use to exit the cec command line interface... be aware !
