Easy fix fan/temp OS6 issues on x86 legacy #no support

I think I have other issues. I cannot get fancontrol to work properly. I put this in place, thank you for doing that!

On the crontab, does */1 mean to use * or 1 in the first field?

Yep I have Pro 6

Does this work on a Pro 6?

Paste the script text into a text file using a Linux compatible text editor. In Windows you can use Textpad. Save the file on the Nas with a name like TempUpdate.I store mine in the directory /data/Tims

Then edit /etc/crontab and add the line below:

*/1 * * * * root /data/Tims/UpdateTemp

I am no expert but Google is a good help for each step.

I am not sure how to build the script. Can you show the commands for that?

Ok upgraded to 6.0.8 and the rrd files have been changed. New script is:

#!/bin/sh
#######################################################
Coretemp="/sys/devices/platform/coretemp.0/temp2_input"
Systemp="/sys/devices/platform/w83627ehf.2576/temp2_input"
Coretemp2="/sys/devices/platform/coretemp.0/temp3_input"
Ct=`cat $Coretemp`
C=`expr $Ct / 1000`
Ct2=`cat $Coretemp2`
C2=`expr $Ct2 / 1000`
St=`cat $Systemp`
S=`expr $St / 1000`
rrdtool update /run/readynasd/stats/temperature_int_deg.rrd N:$C:$S



Edit: There is a problem in 6.0.8 as readynasd also updates the rrd file and gives odd readings on the trend. I have made a hacked elf to stop it, but I would prefer to correct the temperatures it reads and let it update the file itself.

If anyone wants their temperatures logged in Frontview in OS6 its just a standard round robin database that is meant to updated by readystatsd. For some reason my Pro 6 wont log anything. I guess there something wrong in readystatsd. It is running fine but fails to update the temperature databases. It's a compiled elf and I am not able to fix it so I made a simple script called every minute from crontab to sort it out. This is my first go at scripting so its a bit basic! My guess is that it will need to be modded for anything other than a Pro 6. Anyone with a bit more knowledge fancy sorting it properly? Ideally it would be best to decompile the elf and fix it at source.

To create your own /etc/fancontrol file, use pwmconfig command
Here is an example for Ultra 6 model

execute the following commands and give answers according to your system

/etc/init.d/fancontrol stop
 pwmconfig

# pwmconfig revision 5857 (2010-08-22)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

Found the following devices:
hwmon0/device is coretemp
hwmon1/device is it8721

Found the following PWM controls:
hwmon1/device/pwm1
hwmon1/device/pwm2
hwmon1/device/pwm3

Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon1/device/fan1_input current speed: 0 ... skipping!
hwmon1/device/fan2_input current speed: 0 ... skipping!
hwmon1/device/fan3_input current speed: 2265 RPM

Warning!!! This program will stop your fans, one at a time,
for approximately 5 seconds each!!!
This may cause your processor temperature to rise!!!

Please verify that all fans have returned to their normal speed.

The fancontrol script can automatically respond to temperature changes
