@Mailrack Would you mind please posting the output as text? It’s easier to read, mark, search and copy logs this way.
In the screenshot you’ve posted you can clearly see
Failed to read page 111 from file [...] Page read from tablespace is corrupted. as the first error.
So I assume your database is damaged for whatever reason. This is very, very rare as InnoDB has transaction logs and integrated recovery functionality, so there must have something really bad happened.
When googling the error I’ve found following:
I’d recommend in reverting back to an backup before this occurred, to have a consistent database before the corruption occurred. Otherwise search the
my.cnf config in your mailcow directory and restart the container in the recovery mode.
As I can’t recall when I’ve ever had my database corrupted, I’m definitely not a database-recovery-expert and don’t know how ‘good’ the recovery mode is.
