[SOLVED] How to clear journalctl log?

Hello,
How can I remove all the journalctl logs? I used journalctl --vacuum-time=1s command, but logs exist.

Thank you.

The persistent logs are found in the subdirectory contained in /var/log/journal/. You can delete them, but some current portion, up to 100%, remains in memory until flushed to disk and/or shutting down or rebooting.

why do you want to remove them? By the way it is continuously written.

Set up a weekly logrotate job to clear the file and store as many old versions as you want to keep.

What was the problem that was solved? The persistent journal is optional, and configured via /etc/systemd/journald.conf.

Hello,
I removed all files under the /var/log/journal/ directory.

That was your solution. What was the problem that necessitated removing log files?
