Hi hi...
What is the best way to monitor geom software raids (gmirror & gvinum
raid5)???
The solution I'm searching for should be a kind of script which checks
the status, and drops me an email if something is wrong.
I found a nagios plugin, but currently I'm unable to invest enough time
to get nagios up and running for the customer...
Thanks a lot...

I monitor some machines with geom mirrors via Nagios/SNMP.
In nagios:
--------------------------------------------------------------
define service{
use generic-service
host_name host.name.com
service_description gmirror
check_command check_snmp!1!0!UCD-SNMP-MIB::extOutput.1
}
On the machine in snmpd.conf (net-snmp):
--------------------------------------------------------------
exec gmirror /usr/local/sbin/checkgmirror
The script:
--------------------------------------------------------------
#!/bin/sh
mirrorstate=`/sbin/gmirror list | /usr/bin/grep ^State |\
/usr/bin/awk '{print $2}'`
if [ $mirrorstate != "COMPLETE" ]
then
echo "1"
else
echo "0"
fi
Besides crafthing something of your own, there is also:
/usr/ports/net-mgmt/nagios-geom
This is a small Nagios plugin written in PERL and designed to monitor
the state of FreeBSD GEOM devices (specifically mirrors and striped
volumes) from Nagios.
WWW: http://www.geocities.com/ntb4real/proj/geom.htm
To use in Nagios:
In checkcommands.cfg:
--------------------------------------------------------------
define command{
command_name check_geom
command_line $USER1$/check_geom $ARG1$ $ARG2$
}
In your host.cfg:
--------------------------------------------------------------
define service{
use local-service
host_name host.name.conf
service_description mirror
check_command check_geom!mirror!gm0
}
