The title says it all really. I don't want to just kill something that seems so close to the bare metal, and sudo service irqbalance stop says stop: Unknown instance: -- what am I missing? Should I be disabling it somewhere and rebooting?

  • Just curious, what's the purpose of enabling/disabling this? It would seem one would want this enabled... Aug 18, 2014 at 15:34
  • I'll be honest, after 3.5 years or so, I can't remember. Presumably it was causing me a problem at the time -- a buggy interaction with something else, in 10.04 or 10.10, maybe? Aug 19, 2014 at 13:03

And 30 seconds later I found my answer - set ENABLED=0 in /etc/default/irqbalance

Sorry, nothing to see here, move along.

Just a warning that the ENABLED=0 setting in /etc/default/irqbalance setting will not work on recent versions of irqbalance (1.1+), it has been removed a while ago.

As far as I can tell from the source code, there is no way to disable a more recent version of irqbalance without actually stopping the process itself. For example if you run a systemd-based distribution, this would be something like systemctl stop irqbalance.service.

  • So we stop the service and then....... use IRQBALANCE_BANNED_CPUS to control which cpus IRQs are ran on? Feb 4 at 3:57

In 2018 the reason for removing it completely is a warning from the excellent cpufreq Gnome panel applet for managing your processor governor settings, even down to temporarily disabling cores to reduce power consumption provided you have removed irqbalance.
