MariaDB can't find tables mysql.user and mysql.servers

    Details

      Description

      I've been running MariaDB for some time now without problem. I did a minor version upgrade from 10.2.14 to 10.2.15 and now it refuses to start. If I'm reading the error logs correctly, it can't find the tables mysql.user and mysql.servers. I have confirmed that the data files exist, are not corrupted, and they appear to have the proper permissions.

      This is the dump from the error log. The references to the privilege tables are near the end.

      This the systemd output:

      Starting MariaDB 10.2 database server...

      I've run myisamchk on all the tables in the data directory, and I've uninstalled and reinstalled the mariadb-server package. As far as I can tell it hasn't made a difference.
