Sets chassis fan speed based on highest disk temperature

No ability to define specific fans in config file #1

Closed hyperbart closed 4 years ago

hyperbart commented 9 years ago

My fan-naming convention differs from the one defined in the script, config file does not offer to specify fan-device.

Furthermore it does not allow to specify more than one fan?

louwrentius commented 8 years ago

My motherboard controls the fan speed of all fans with one device. So I can't test or debug a solution with multiple different fans and devices unfortunately.

However, if you are still interested and are willing to test I can alter the code so that it sets the speed on multiple /sys fan devices. (just a for loop over a list of devices.)

hyperbart commented 8 years ago

Sure! Would be happy to test.

louwrentius commented 8 years ago

It took a while but I now have committed a new version. You can specify multiple devices in the INI file separated by a comma. If the script does an operation, it loops over all devices and performs the operation on all of them. Feedback is appreciated.

Hi,

Maybe set mode to 'smart' instead of 'controller' unless you use the megacli stuff used with lsi controllers.

I probably should change the default. Make sure smartmontools is installed.

However, I did notice sometime the scripts stops outputting to syslog, I will keep an eye on it.

It effectively stops logging to syslog after a while

When I stop the script and restart it, all seems to be well for a while again.

louwrentius commented 8 years ago

If it stops logging to syslog it probably crashed? Can you run it from te console manually if you did not already? Might see python error.

I notice that the script is turning the fans lower and lower (not dir real because of safety mechanism) because the target temp is way higher than the actual temp it seems. Y

Do you mind telling me how to get the debug output exactly?

I'm running the following command right now:

./Louwrentius/storagefancontrol/storagefancontrol export DEBUG=true

But not seeing anything on the console, is the export debug=true a config parameter for the config file?

louwrentius commented 8 years ago

Sure! First run the export debug line to set the environment and then just run the script ./storagefancontrol -> you should see output in the console normaly seen in syslog. Then let it run for a while.

I seem to have some problems running the script in debug, can't get it to stop with Ctrl C and no output is shown.
