 +======= monitor gmirror from NRPE / cron for FreeBSD =======
  
 +I wrote this little check-script for nrpe/nagios to get the status of various gmirror volumes in a box, and output the failed volumes if any such exist.
 +
 +===== Syntax =====
 +
 +''$path/check_gmirror.sh [email] [email]''
 +
 +If no arguments are specified, the script will assume its run for NRPE.
 +If one or more email addresses are specified, the script will send an email in case an array reports an error.
 +
 +===== Output =====
 +''gm3: DEGRADED / gm0: rebuilding / gm2: ok / gm1: ok''
 +
 +Failed/rebuilding volumes will always be first in the output string, to help diagnose the problem when recieving the output via pager/sms.
 +
 +==== Output Examples ====
 +
 +^ output ^ description ^
 +| ok |The device is reported as ok by the smart array controller |
 +| DEGRADED |The RAID volume is degraded, it's still working but without the safety of RAID, and in some cases with severe performance loss. |
 +| rebuilding | The RAID is rebuilding, will return to OK when done |
 +| starting | The geom device is currently starting, you shouldn't see this and will return an unknown code to nagios |
 +| unknown state | Volume is in an unknown state. Please report this to me (soren at klintrup.dk) so I can update the script
 +include the following output. ''gmirror status'', ''gmirror list'' |
 +
 +===== Compability =====
 +The script should work on any <nowiki>FreeBSD</nowiki> platform until gmirror changes input/output syntax, I have tested the script on the following platforms
 +
 +  * <nowiki>FreeBSD 6.2</nowiki>
 +  * <nowiki>FreeBSD 6.3</nowiki>
 +  * <nowiki>FreeBSD 7.0(amd64)</nowiki>
 +  * <nowiki>FreeBSD 8.0(amd64)</nowiki>
