Earlier this year, I wrote an article on how to control the fan speed of your Lenovo SA120 JBOD from within FreeNAS.

It turns out this doesn’t work on the newest FreeNAS 10 ( FreeNAS Corral ), but the reason is simple.

When I went to run the Fan Speed control script, I got an error returned:



I pondered this a bit, but the first thing I thought of was to execute python2 and see if I got a shell…


OK! So, I thought that maybe they upgraded to Python3 — I haven’t really looked at the release notes. I kind of just jumped ship and upgraded. My iSCSI still doesn’t map to my VMWare hosts. Anyways…

I simply ran python2 fancontrol.py 1 and the jet turbines went silent.

I hope this helps you. Thanks for reading!
