Slow system

GermanGT · August 18, 2018, 9:56am

Sometimes my lapton becomes very slow. Even reboot or shutdown the laptop takes like 10 or 15 minutes. But then the system cannot boot, it display a message about “try systemctl reboot or systemctl default” The last don’r work, “systemctl reboot” takes a lot of time but eventually the system boot again and I can login into it. However, sometimes the system is still slow, with the difference that I cannot shutdow or reboot the system. If I open a terminal (it takes like 5 minutes to display the window) the prompt is not displayed. The system monitor (other 5 minutes to display it) show something called “systemd journal” is running and using 50% of processor. So I force the shutdown pressing the start button of the laptop. And then I need run “systemctl reboot” like two or three times and eventually the system boot normally. This is not frequent, but I loos my time trying to solve it (two or three hours). Is “systemd journal” the problem? Is possible disable it? Any advice? Thanks.

what is output from

btrfs filesystem du -s --human-readable /

and

snapper list

You may be operating with a root filesystem running low on freespace.

Please repeat logged in as root and so that output is in English and properly formatted by using code tags, # in input menu:

lang=C /sbin/btrfs filesystem du -s --human-readable /

and

lang=C /usr/bin/snapper list
