CentOS - Sep 2017 - Error "corrupted or uncleanly shut down, renaming and replacing" in CentOS 7 clean install

Hi all,

 I have installed two new CentOS 7.1708 (fully patched, kernel release is
3.10.0-693.2.2.el7.x86_64) as virtual guests, one is using lvm and the other not
and both use XFS as filesystem. In both, I see the following systemd's error
after a few minutes:

systemd-journald[779]: File
/run/log/journal/3abe0470ce564669b797cb4c416f1ac0/system.journal corrupted or
uncleanly shut down, renaming and replacing.

 Is it a bug? Or do I need to change some option in journald.conf's file?
Actually, I have changed Storage's option to "volatile".

Thanks.
