Stop tinkering. Don't try to be too clever. Undo those diagnostics. Rely on journal only.
I got message -- only 1 gig left in root. Then apps stopped running. I did restart and no normal start only black screen. Alt-f2 got me to a login. I got to root and /var/log. messages file was 65 gig. I deleted it. A restart was normal. Subsequently, I deleted all the files in /var/log/journal that I created. Maybe I should delete entire journal directory?
Nope. Journal is a matured application. Use this instead:
Code:
erlangen:~ # journalctl --vacuum-size 1G
Vacuuming done, freed 0B of archived journals from /run/log/journal.

I also made sure that systemd.journald.conf had "storage=auto" as it was originally. Anything else, I should do to make sure messages are under control? Now I am back at 30% root use out of 100 gig.
