    Description

      Hi,
      we tried to setup a new database Server with Debian 9 , MariaDB 10.2 and mysqld_multi with several instances.
      We always get this message:

      #mysqld_multi report
      		 
      Reporting MariaDB servers
      		 
      No groups to be reported (check your GNRs)

      In MariadDB 10.2.14 your test Multi Instance is working:

      #msqld_multi report
      		 
      Reporting MariaDB servers
      		 
      MariaDB server from group: mysqld16 is not running

      This happens with MariaDB 10.2.15, 10.2.16 ad 10.3
      Mysqld_multi.log has no helpful entries:

      Reporting MariaDB servers
      		 
      No groups to be reported (check your GNRs)
      		 
      mysqld_multi log file version 2.20; run: Mo Aug  6 15:15:37 2018

      best regards
      Andreas
