    Description

      If you mistype a parameter or use a valid parameter but in the wrong section MariaDB fails to start logging only two rows in the error log:

      [root@tossanc 10209]# grep fantasy mh-my.cnf.10209 
      fantasy_parameter=yes
       
      [root@tossanc 10209]# mh service start 10209

      I actually encountered this problem when configuring `streamfmt` in the wrong section, [mysqld] instead of [sst].
      Since I faced many times the case that a Galera node would not join and only those two lines were added to the error log, I suspect now that in most cases was just a wrong or mistyped configuration parameter.

      Imho It would be the case to point to the reason why the server failed to start, either non existing parameter or non existing for that section.
