Hi!
I've seen a strange behavior of nagios with a very simple check script.
the relevant part of the script:
#########################################################################
MAINTCNT="`/usr/sbin/metastat |grep -i maint |wc -l`"
RESYNCNT="`/usr/sbin/metastat |grep -i resync |wc -l`"
NOTOK=0
status=$STATE_UNKNOWN
if [ $RESYNCNT -gt 0 ]; then
NOTOK=1
TEXT="WARNING - One or more disks are in resync state. "
status=$STATE_WARNING
fi
if [ $MAINTCNT -gt 0 ]; then
NOTOK=1
TEXT="CRITICAL - One or more disks are in maintenance state."
status=$STATE_CRITICAL
fi
if [ $NOTOK -eq 1 ]; then
echo $TEXT
datum=`date`
echo $datum $status >> /tmp/svm.debug
exit $status
fi
echo "OK - There is no maintenance necessary!"
exit $STATE_OK
#########################################################################
when executing the script from command line, the return code always is 2
and the output always is "CRITICAL - One or more disks are in maintenance
state." (because there is one dead disk) => thats ok
when nagios executes the script, the output always is "CRITICAL - One or
more disks are in maintenance state." but the return code sometimes is 0
and sometimes is 2 => thats not good
