MariaDB restart warning

Ok, Im setting up a new server with cpanel 68.0.37 release. I upgraded mysql 5.6 to mariadb 10.1, that"s ok. I tested some sites before the dns move and all is ok. Mysql -v shows that mariadb is running. Now when I restart mysql (service mysql restart) I get this error: Restarting mysql (via systemctl): Warning: mysql.service changed on disk. Run 'systemctl daemon-reload' to reload units. [OK] I run the command systemctl daemon-reload and then again service mysql restart and I get the same error. Is it a cpanel bug? By the way at WHM - Home - Server - Service Status - Service Status the mysql services says 5.6.38-1 is that ok? I wait your comments. Thanks!
