How to delete /var/log/journal

Yes you can delete everything inside of /var/log/journal/* but do not delete the directory itself. You can also query journalctl to find out how much disk space it’s consuming:

$ journalctl –disk-usage Journals take up 3.8G on disk. You can control the size of this directory using this parameter in your /etc/systemd/journald.conf:

SystemMaxUse=50M You can force a log rotation:

$ sudo systemctl kill –kill-who=main –signal=SIGUSR2 systemd-journald.service NOTE: You might need to restart the logging service to force a log rotation, if the above signaling method does not do it. You can restart the service like so:

$ sudo systemctl restart systemd-journald.service
