Hi, 12th of October I started the topic" Maria-db refuses to start". With the help offered in the conversation following I could access my data by manually starting an older version of Mariadb. I then dumped my tables with mysqldump, one by one, successfully. I also dumped the mysql table. Final advice was to purge all reminiscences of the older versions, and make a fresh start by installing the version of my OS (OpenSuse Tumbleweed). In that new environment, import the dumped data. A few questions remain: - should I, after the install process of the OS version (at the moment 10.10.2-1.1) take further actions to get a fully functioning system? - should I import the dumped "mysql" table? - if yes, should I do that before or after importing the user data? Or doesn't that matter? Again, thanks for your answers! kind regards, Jogchum
