cciss_vol_status exclude /dev/sg2 #149

PitoneMaledetto · 2016-09-15T11:55:27Z

Hi there I am running the plugin with -p cciss
I get this:
Remote command execution failed: cciss_vol_status: open /dev/sg2: No such file or directory

How can I exclude the missing directory, is there a switch to do so?

If I manually run on the server:
sudo /usr/bin/cciss_vol_status -V /dev/sg0 /dev/sg1

I get everything I need.
Thanks

PitoneMaledetto · 2016-09-16T09:44:22Z

Proposed solution:
A switch for the use of the cciss plugin in order to specify the number of sg# directories to check or to avoid non existent ones.

glensc · 2016-09-16T20:20:51Z

i was rather thinking iterate over /dev/sgX nodes and skip ones that doesn't exist.

glensc · 2016-09-16T20:31:41Z

i suppose you don't have lsscsi program installed? and if you do, show lsscsi -g and it's version lsscsi --version

Iterate seems a good way of solving the non-existent sgX

glensc · 2016-09-20T21:11:24Z

lsscsi tool is used to detect devices more reliably. try it.

glensc · 2016-09-20T21:13:38Z

also include command whose output you pasted in those ls -l pastes, to see what path you did ls on

PitoneMaledetto · 2016-09-21T08:59:51Z

First run:
ls -rtl /dev/disk/by-id/
Second run:
ls -ld /sys/block/sd*/device

glensc · 2016-09-21T15:12:00Z

edited your post. hopefully correctly.

i'm waiting for you to try installing lsscsi tool and see does the plugin work more as expected with the tool present.

PitoneMaledetto · 2016-10-12T09:45:28Z

It seems that when you force the check using the -p flag that the error is triggered.
if:
sudo ./check_raid then:

WARNING: cciss:[/dev/cciss/c0d0(Smart Array P400): Volume 0 (RAID 1): OK, Volume 1 (RAID 5): OK]; dm:[No devices to check]; hpacucli:[Smart Array P400: Array A(OK)[LUN1:OK], Array B(OK)[LUN2:OK]]

which would be the case to ignore dm instead of triggering a WARNING

but if:
sudo ./check_raid -p cciss then:

Can't locate object method "new" via package "App::Monitoring::Plugin::CheckRaid::Plugins::smartctl" (perhaps you forgot to load "App::Monitoring::Plugin::CheckRaid::Plugins::smartctl"?) at ./check_raid line 1879.

the first check without flags used cciss as well as dm and hpacucli but cciss did not fail.

glensc · 2016-12-19T19:26:57Z

fixed smartctl import, is this sufficient?

what is /usr/local/nagios/libexec/./check_raid.pl? how did you obtain it?

also the dist version of plugin is self contained!

PitoneMaledetto · 2016-12-20T11:07:25Z

ermm I downloaded the new version from the Download button on the code page...
version 4.0.2 works ok:

root@my-nagios-server:/tmp# /usr/local/nagios/libexec/./check_raid -V
check_raid 4.0.2

...self contained means it should not exit with the missing module error...I might be wrong...

glensc · 2016-12-20T11:20:45Z

don't know what is "download button on the code page", no urls given and no screenshots...

instructions from readme:

https://github.com/glensc/nagios-plugin-check_raid#installing - released versions, including "snapshot" release
https://github.com/glensc/nagios-plugin-check_raid#development - to use development version using git.

yes, self contained means it needs just perl engine and the check_raid.pl script

PitoneMaledetto · 2016-12-20T11:27:01Z

got it...I will let you know as soon as tested. Thanks
