Convert bb-mdstat for Variables XYMON - MDADM Changes config on Reboot even when in GOOD STATUS - Script not working
John,
(cc’ed the list)
unfortunately this re-ordering happens. — not only for mdraid (linux soft raid) but also for megaraid (LSI controllers) for instance. Without sacrificing the simplicity of raid-monitor I see no solution for this. Excluding lines that might permute _could_ be an option but at the risk of “missing” some bad state of the RAID.
That being said: In a server setup where machines typically do not boot that often that’s an acceptable trade-off (for me).
To ease the “recreate reference file”-pain you could have a mini-script (ssh line) on the xymon-server that re-creates the file after you checked the raid-status on the Xymon web interface (ssh my-server ‘/usr/lib/xymon/client/bin/xymoncmd /usr/lib/xymon/client/ext/raid-monitor -r).
All the best Thomas

I love this concept, but it seems to have a flaw with MDADM. I will still be using it @ work with AARCONF, since I don’t think that will have the same problem…. But here is the issue, my sd* are in a different order after rebooting which caused red status, needed to rebuild known “good” config.

Anything I can do? I can’t re-create the “known good config” automatically on reboot, or how would I know its “known good” without looking at it!

/proc/mdstat monitoring is included in newer Xymon clients (producing a 'raid' status).
alternatively you might want to take a look at my raid-monitor extension which provides good/bad monitoring for afraid, LSI megaraid, 3ware/LSI, Adaptec aacraid: http://www.it-eckert.com/software/raid-monitor/ <http://www.it-eckert.com/software/raid-monitor/> Cheers Thomas

Hello XYMon Guru’s!
I am trying to configure bb-mdstat found on https://wiki.xymonton.org/doku.php/monitors:bb-mdstat <https://wiki.xymonton.org/doku.php/monitors:bb-mdstat> , but all the variables point to BB*** and it doesn’t work, I think all the “scripting” would work If I could just figure out how to set the variables correctly, any chance we could get this updated for XYMON Variables.?
Testing :
donut at FileServer:/usr/lib/xymon/client/ext$ ./bb-mdstat.sh
./bb-mdstat.sh: 62: [: unexpected operator

Manually set :

Manually set :
if [ ! -d "$BBTMP" ] ; then # GET DEFINITIONS IF NEEDED
echo "*** LOADING HOBBITCLIENT.CFG ***" . $BBHOME/etc/xymonclient.cfg # INCLUDE STANDARD DEFINITIONSFi
And this is where I draw a blank…
