This plugin checks all RAID volumes (hardware and software) that can be identified.
This is supposed to be a general plugin to run via NRPE. It checks for the various RAID systems, and verifies they are working correctly.
Some checks require root permission, that is acomplished using sudo.
Neccessary sudo rules (detected for your system), can be installed when
check_raid is invoked with -S argument. You need to be root user and it
will add required lines to the sudoers file.
Download directly from github master (with wget or curl):
wget https://raw.github.com/glensc/nagios-plugin-check_raid/master/check_raid.pl -O check_raid.pl
curl https://raw.github.com/glensc/nagios-plugin-check_raid/master/check_raid.pl > check_raid.pl
chmod +x check_raid.pl
or download in tar format master checkout:
wget https://github.com/glensc/nagios-plugin-check_raid/tarball/master/check_raid.tgz
tar xzf check_raid.tgz
cd glensc-nagios-plugin-check_raid-*
you can grab older releases under tags button
next, setup sudo
./check_raid.pl -S
test run:
./check_raid.pl
for some RAIDs there's need to install extra tools, see Supported RAIDs
./check_raid.pl [-p|--plugin <name>] [-w|--warnonly]
./check_raid.pl -S
./check_raid.pl -l
Command line arguments
-V --version Print check_raid version
-d Produce some debug output
-S --sudoers Configure /etc/sudoers file
-W --warnonly Don't send CRITICAL status
-p --plugin <name(s)> Force the use of selected plugins, comma separated
-l --list-plugins Lists active plugins
Bugs should be reported to github issue tracker. Before opening new issue, check that your problem is not already reported, also before opening bugreport, check that the bug is not already fixed by testing with master branch.
As it's unlikely I have same hardware as you, not to mention same condition that is not handled,
I ask you to provide output of the commands the plugin runs.
What commands plugin runs, can be seen with -d option:
DEBUG EXEC: /proc/mdstat at ./check_raid.pl line 345.
DEBUG EXEC: /usr/local/bin/arcconf GETSTATUS 1 at ./check_raid.pl line 345.
DEBUG EXEC: /usr/local/bin/arcconf GETCONFIG 1 AL at ./check_raid.pl line 345.
Capture each command output to a file:
cat /proc/mdstat > mdstat.out
/usr/local/bin/arcconf GETSTATUS 1 > arcconf-getstatus.out
/usr/local/bin/arcconf GETCONFIG 1 AL > arcconf-getconfig.out
In this particular example, the space between 1 and > is important, because 1> means different thing
(tells shell to redirect fd no 1).
The redirection commands should provide no output, all should be directed to .out file.
If they do, it means the command produced output to stderr stream as well.
Depending on the output, it may make difference what that is,
usually those messages are small and can be included with bugreport.
The command output should be shared by some pastebin service, maybe even gist. because it may be important how the output is formatted, some invisible bytes may make the difference. Also it's annoying to format large output in github issue tracker.
Supported RAIDs that can be checked:
- Adaptec AAC RAID via aaccli or afacli or arcconf
- AIX software RAID via lsvg
- HP/Compaq Smart Array via cciss_vol_status (hpsa supported too)
- HP Smart Array Controllers and MSA Controllers via hpacucli (see hapacucli readme)
- HP Smart Array (MSA1500) via serial line
- Linux 3ware SATA RAID via tw_cli
- Linux DPT/I2O hardware RAID controllers via /proc/scsi/dpt_i2o
- Linux GDTH hardware RAID controllers via /proc/scsi/gdth
- Linux LSI MegaRaid hardware RAID via CmdTool2
- Linux LSI MegaRaid hardware RAID via megarc
- Linux LSI MegaRaid hardware RAID via /proc/megaraid
- Linux MegaIDE hardware RAID controllers via /proc/megaide
- Linux MPT hardware RAID via mpt-status
- Linux software RAID (md) via /proc/mdstat
- LSI Logic MegaRAID SAS series via MegaCli
- LSI MegaRaid via lsraid
- Serveraid IPS via ipssend
- Solaris software RAID via metastat
You might need to install following tools depending on your raid:
- CmdTool2: CmdTool2 SAS RAID Management Utility
- arcconf: Adaptec uniform command line interface
- cciss_vol_status: http://cciss.sourceforge.net/
- megarc-scsi: LSI Logic MegaRAID Linux MegaRC utility
- mpt-status: LSI RAID controllers - http://www.red-bean.com/~mab/mpt-status.html
- tw_cli-9xxx: 3ware SATA RAID controllers - http://www.3ware.com/
