[Nut-upsuser] UPS Reboots when Pi Reboots!

[James Fischl]

Thank you Roger, I appreciate the response. I'll have to check my commands, I believe I started it with those systemctl commands you provided. What I can say is that oddly enough after completing the server config and after two more reboots a reboot of the Pi doesn't seem to be causing the UPS to reboot anymore. I have a bit more config to do on slave machines tomorrow but after that I'll do testing - including pulling the plug - and see what happens.

I do recall from reading the documentation that the master can initiate a reboot of the UPS and that in a shutdown event I believe it's supposed to do actually trigger a delayed shutdown to occur after the master's own power-off. How that gets mixed up with an OS reboot is odd to me...perhaps something scripted in relation to the NUT service stopping?

Google searching did by the way yield one and only one other mention of something like what I experienced: https://serverfault.com/questions/858267/network-ups-tools-nut-causing-ups-to-reboot. So at least I'm not completely nuts, just partially.

Thanks again for your help.

The usual way of starting NUT is

  systemctl start nut-server.service
  systemctl start nut-monitor.service

The driver will be started automatically by upsd (nut-server).  What happens if
you start that way?

what happens when you pull the wall power?
