Bug Description
I've been trying to figure out why my HDD keeps on flushing metadata out every minute on an idle laptop and discovered that gsd-color opens /usr/share/
Can this periodic open/closing be fixed or at least try to use O_NOATIME on the opening to reduce the metadata atime updates?
I diagnosed this by running:
sudo fnotifystat -v -x/sys,/proc,/home
one can see that the gsd-color is opening and closing the file.
Looking deeper, I used health-check on gsd-color to gather the attached activity log of 5 minutes of activity of gsd-color on the idle machine.
To capture the activity I used:
sudo health-check -p gsd-color -d 300 -f -r -v > gnome-gsd-
I'm pretty sure that opening the zoneinfo file with O_NOATIME will avoid the metadata atime flushes and because the data has not changed on disk it should avoid the HDD spinup/spindown cycling. Alternatively, can the regular zoneinfo reads be avoided to save power?
This seems like an identical bug as: https:/
