Do you have enough free disk space? Often the MariaDB service will not start due to lack of free space.
Examining the MariaDB log file can also understand the cause of the problem.

I decided to completely remove plesk and install everything as new.
I have CentOs 7.9.2009 and Plesk Obsidian 18.0.33.0.
Could you give me a guide for a clean uninstall?

Reinstall OS with formatting disk drive.

I am working via ssh because i use a dedicated server. Is there no way to uninstall without formatting the whole system?
