Monitor RAID arrays

[TimStallard]

vms, vms-b53-1 and auth2 all use hardware raid 1 - we should be monitoring the health of these arrays.

Looks like nagios-plugins-contrib contains checks we could use, though relying on utilities for individual controllers.

Seems easy enough to get going:

root@vms-b53-1:/opt/raid# wget https://docs.broadcom.com/docs-and-downloads/raid-controllers/raid-controllers-common-files/8-07-14_MegaCLI.zip
root@vms-b53-1:/opt/raid# unzip 8-07-14_MegaCLI.zip 
root@vms-b53-1:/opt/raid# cd Linux/
root@vms-b53-1:/opt/raid/Linux# rpm2cpio MegaCli-8.07.14-1.noarch.rpm | cpio -idmv
root@vms-b53-1:/opt/raid/Linux# mv opt/MegaRAID /opt/

Then for the nagios side, install check_raid, generate sudo config and test:

root@vms-b53-1:/opt# apt install --no-install-recommends nagios-plugins-contrib
root@vms-b53-1:/opt# /usr/lib/nagios/plugins/check_raid -S -p megacli
Updating file /etc/sudoers.d/check_raid
/etc/sudoers.d/check_raid.new.18809: parsed OK
/etc/sudoers.d/check_raid file updated.
check_raid OK - sudoers updated

root@vms-b53-1:/opt# sudo -u nagios /usr/lib/nagios/plugins/check_raid -p megacli
OK: megacli:[Volumes(1): DISK0.0:Optimal,WriteCache:DISABLED; Devices(2): 00,01=Online]
root@vms-b53-1:/opt# echo $?
0

Will need some thought on how to handle in netbox and automate the checks on monitor2 (or just make them manual?)

All done on VMS, ignore on AUTH2 for now

the new routers also have hardware RAID, so I think this would be a good opportunity to do this properly and get the setup in ansible
