Fixed tracker-store’s CPU hogging issue on Arch Linux

I think it’s since when I updated Arch Linux a while ago the tracker-storeprocess has become CPU-hogging and it can drain the battery pretty quickly and turn my laptop into a heater.

Obviously there are people experiencing this issue already, but most of them that I found were trying to disable the Gnome tracker. I’d hesitate to do that because the tracker’s purpose is to index stuff so when I hit the super key and type, relevant things will come up quickly. Also as I’m a big fan of Gnome Shell, I trust the team wouldn’t just release a buggy program and left it broken for months.

My trouble-shooting 101: if I want to see what the program is complaining, run it from the command line!

tracker daemon -s
 Starting miners…

I don’t think those are the root causes though.

Later I found this issue for Gnome 3.12 and I think it could be my case as well. To my surprise this fixed my issue with tracker-store easily.

First, stop tracker-store gracefully with tracker daemon -tThen I found:

The 776MB meta.db surely is bloated, as I only have around 200GB of personal files. Since they are only meta-data, deletion won’t hurt. 

rm -rf ~/.cache/tracker/
rm -rf ~/.local/share/tracker/

tracker daemon -s

All good now 🙂
