Scripting feature within hd-idle

[wmd1942]

I have a usbrelay module to control the cooling fan through a simple script command. Is there any way to provide the scripting capability so the scripts could be invoked when disk spin down/up?

Short answer: no.
Long answer: You could figure a way to pull /var/log/syslog for sdx spindown entries.

I wrote a bash script to pull hd-idle entry from syslog every minute. It works well. Thanks for the suggestion.

#!/usr/bin/bash

while true; do
hd_state=$(cat /var/log/syslog | grep "hd-idle" | tail -n 1 | awk -F ":" '{ print $4 }' | awk -F " " '{ print $2 }')
if [[ $hd_state = "spindown" ]]
then
/root/cooling-fan-off.sh
else
/root/cooling-fan-on.sh
fi
sleep 60s # run every 1 min
done
