check_gmirror


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:



tank: DEGRADED / data: rebuilding / system: ok



Failed/rebuilding volumes will always be first in the output string, to help diagnose the problem when recieving the output via pager/sms.
