[SOLVED] systemd fancontrol fails to start at boot

Hi,

I've just switched to systemd from initscript and I can't resolve an issue: fancontrol fails to run at boot time, but it works properly when manually started.

Logs:

UNIT               LOAD   ACTIVE SUB    JOB DESCRIPTION
colord.service     loaded failed failed     Manage, Install and Generate Color Profiles
fancontrol.service loaded failed failed     Fan control daemon

 #  systemctl status fancontrol

Oct 23 07:23:51 arch fancontrol[434]: Configuration appears to be outdated, please run pwmconfig again

I thought it is a timing issue, so I tweaked fancontrol.service, but didn't helped:

#  cat /etc/systemd/system/fancontrol.service
.include /usr/lib/systemd/system/fancontrol.service

[Unit]
Requires=sensord.service
After=sensord.service

Any advice?
Thanks.

Re: [SOLVED] systemd fancontrol fails to start at boot

I also ran into this problem a while back and it does seem to be a timing issue. I believe the modules used for hardware monitoring aren't always loaded before fancontrol.service starts (due to systemd's nature of loading everything in parallel). lm_sensors package includes an lm_sensors.service file which loads the modules that were added by sensors-detect to /etc/conf.d/lm_sensors. So in /etc/systemd/system/fancontrol.service try substituting the lines containing sensord.service with lm_sensors.service. At least that seems to have helped me. Good luck!

I think you are right. Apparently it seems I mixed up sensord with sensors.  Thanks.

Since this is one of the first web search hits for the error "Configuration appears to be outdated, please run pwmconfig again", the upstream bug is:  https://github.com/lm-sensors/lm-sensors/issues/227

It contains workarounds.
