Fix for chromium BrowserMetrics filling filesystem: '/dev/mmcblk0p2' Disk Full, '/home/pi/.config/chromium/BrowserMetrics' fills entire disk, chromium will not load, FullPageOS logo shows. Also fix for Also add fix for changing hostname (clear chromium/Singleton*)

[richardhuishwork]

What were you doing?

Chromium BrowserMetrics is filling filesystem
Also add fix for changing hostname (clear chromium/Singleton*)

After a while the SD card becomes full.
running sudo ncdu -x at the drive root shows that the disk /dev/mmcblk0p2 is 100% full.
This is due to /home/pi/.config/chromium/BrowserMetrics filling the entire disk

Chromium will not load, FullPageOS logo shows, cursor works, VNC works.

Suggested fix...

On the script that loads FullPageOS add the following commands to run:

rm -R /home/pi/.cache/chromium/Default/Cache
rm -R /home/pi/.config/chromium/BrowserMetrics/*.*
rm -rf ~/.config/chromium/Singleton*

If you are building FullPageOS - provide a build.log that is created for the build

I think this would fix:
#508

I tested it and it is working if added to run_onepageos

rm -R /home/pi/.cache/chromium/Default/Cache
rm -R /home/pi/.config/chromium/BrowserMetrics/*.*
rm -rf ~/.config/chromium/Singleton*




while true
do
    if [[ $(curl -sL -b cookiefile -w "%{http_code}\\n" -H "user-agent: ${USER_AGENT}" "$(/opt/custompios/scripts/get_url)" -o /dev/null) =~ ^([23][0-9]{2,2}|401)$ ]] || grep -q disabled "/boot/firmware/check_for_httpd" ; then
      xdotool mousemove 9000 9000
      /opt/custompios/scripts/start_chromium_browser
    fi
    sleep 1
done

It does not seem to me that this is a solution, more like a workaround:

rm -R /home/pi/.cache/chromium/Default/Cache
rm -R /home/pi/.config/chromium/BrowserMetrics/*.*
rm -rf ~/.config/chromium/Singleton*

What exactly is filling it up? What is in that folder?
What size sd card? perhaps its too small?

[richardhuishwork]

Hello, the SD card is 32GB and filled it within a few weeks in the /home/pi/.config/chromium/BrowserMetrics/ folder.

A full apt update & apt upgrade has been performed.

The folder fills with .PMA files E.G BrowserMetrics-60B60603-3D7326.pma

I am not sure how to disable it from the build, but it looks like you can disable it according to this:
https://askubuntu.com/a/1343947/116460

Disable/enable:

    Open Chrome/Chromium, More, Settings.
    Under "You and Google" select "Sync and Google services".
    Turn on or off "Help improve Chrome's features and performance"

[richardhuishwork]

I'm doing everything from SSH/VNC, any idea how to get to the settings page?

Update: Ah "Ctrl + T" escapes the tab.

[richardhuishwork]

Settings as default, seem to already be off or missing.
