Hi
I was running this script in ubuntu server 22.04 in a pr2100 for a long time, but suddenly it stopped working, so I reinstalled it, and after that everytime the system boots, it inmediately shuts down when running the daemon.

If I remove it, everything works, except fan control.

If I reinstall the script, it starts working, the fans spin down, but after a sudo reboot, it starts shutting down after booting.
If I use sudo shutdown it does shutdown, and when powering on, it boots fine, but the wdnas-hwtools daemon is not working and the fans are spinning at full speed.

It looks like when the daemon tries to change fan speed, it crashes an panics.

install.sh (the fan spins down after the script)

gonzalo@pr2100:~/wdnas-hwtools$ sudo ./install.sh

just found this on the log when doing systemctl stat wdhwd

2023-08-03 12:30:18,423 - __main__ - ERROR - WdHwDaemon: Daemon failed with PMCCommandRejectedException: ; exiting
2023-08-03 12:30:35,059 - __main__ - ERROR - FanControllerImpl: Overheat condition requires immediate shutdown

Did you ever find a resolution? I am struggling with similar issues

This is how I worked around the issue on my PR2100:

sudo crontab -e

enter these 2 lines at the end of the file:

*/3 * * * * systemctl start wdhwd.service
*/3 * * * * wdhwc led -P -s -G

This will attempt to start the service every 3 minutes. This should actually kick in only once after boot. Still, the service never comes up on boot AND a reboot will result in the unit shutting itself down. It's not ideal but it somewhat remedies the issue.

Also, the second line will turn the power LED to solid green to indicate that the service is running although that should be audible as well :)

I think I did something similar, manually starting the service. I forgot about this issue, but it's still there.
Maybe it has to do with the serial console being on the same serial port? (I used serial console to install Ubuntu)

edit: this was my solution on crontab
@reboot sleep 90 && systemctl restart wdhwd.service

if I set the fan speed to 0, it inmediatly shuts down
