I however discovered that certain default mdadm installs tend to do a full check on the array on a weekly basis, which triggers a false positive.

if [ "$status" = 0 ] && \
[ $(cat /sys/block/${md}/md/degraded) = 1 ] && \
$( echo $mdadmoutput | grep -e State.*resyncing -e State.*recovering >/dev/null )

then your device isn’t really degraded, but just doing a full check.

full script see http://support.ginsys.be/wsvn/scripts/zabbix/mdcheck.sh
