I think I have checked every post in the internet. Thing is my MySQL (MariaDB) won't come up and after much testing I have seen it is because of the InnoDB files.

I have tried with different innodb_force_recover and also with mysqld_safe, also with online tools and with every tut I have found.

I'm pretty desperate at this point, so any kind of help is welcome.

The log that matters is this one:

  • A nicer formatted log message would help. It also appears to be truncated so a more complete log might help. What MariaDB version? What OS/Distribution? – danblack Nov 27 '18 at 21:49

MDEV-13939 Page directory corruption: infimum not pointed appears to be a bug upstream that has some tips on recovery.
