Hello - I have ran into a problem that maybe someone else has hit and knows a solution for it.  I recently upgraded my OpenSuSE 15.2 x64 version to OpenSuSE 15.3 x64 and installed all additional updates and patches that were suggested for 15.3.  Most of the upgrade succeeded, all except Mariadb. Google has not been helpful either. My understanding of Mariadb is that after a new install of a new version it is suppose to automagically update and fix the databases from the older version, when the server is restarted, but I think this is failing. I found the  upgrade log file for Mariadb and it appears to be reporting some kind of corruption has occurred. This is preventing the mariadb (mysql) server from even starting, so it is not possible to use queries to find and repair the database. -

On a hunch, I decided to install the OpenSuSE OSS repository for 15.2 and this allowed me to drop back and install version 10.4.13-lp152.1.1 of the mariadb server, client, errormessages, and tools packages. (OpenSuSE 15.3 wants to install version 10.5.12-3.9.1 of these mariadb packages.) And lo and behold the previous 10.4.13-lp152.1.1 package works fine!

So what gives? Any idea why the upgraded version of mariadb packages are failing to upgrade and support my databases? As I said I have tried Googling for an answer but no joy finding one. A lot of the proposed solutions, Google found, assume the mariadb server is up and running (hump!) so the example solutions given, use mysql queries and commands to fix corrupt databases and tables. I should also point out that AFAIK most, if not all of my database structures are using InnoDB and not the older MYISAM structures (although the mysql database itself appears to have both). I did make a mariadb backup of all the databases but without the ability to start the mariadb server I don't know how to make use of this backup file to reconstruct all the databases and their tables etc.

    Thanks in advance for any and all advice on how to upgrade my mariadb server.    Marc Chamberlin
