Hi!

It seems I found the solution, but I still wonder: Is it a bug?
After reading the manual, I tried:
v02:~ # journalctl --flush

Then I saw:
Aug 11 09:41:24 v02 systemd-journald[12614]: Time spent on flushing to
/var/log/journal/1b5c6954ed9447fabb805f9da0419e15 is 29.811ms for 2696
entries.
Aug 11 09:41:24 v02 systemd-journald[12614]: System Journal
(/var/log/journal/1b5c6954ed9447fabb805f9da0419e15) is 8.0M, max 4.0G, 3.9G
free.

Why didn't the service restart work?

The permissions are unchanged, BTW:
v02:~ # ll -d /var/log/journal/
drwxr-xr-x 1 root root 64 Aug 11 09:41 /var/log/journal/

Ulrich
