Symptoms

MariaDB service goes down intermittently with errors such as:

# journalctl -u mariadb
localhost mariadbd[1940]:[ERROR] mariadbd: Table './database_name/table_name' is marked as crashed and should be repaired

The database files from the error have corrupted tables.

Log into Plesk
Go to Domains > example.com > Databases and click Check and Repair for the required database

Linux-based operating systems:
1. Connect to server over SSH
2. Execute the below command substituting required table and database:
  
  # mysqlcheck -r database_name table_name -uadmin -p`cat /etc/psa/.psa.shadow`
Windows-based operating systems
1. Connect to server via RDP
2. Open command-line console cmd.exe with Administrator privileges.
3. Execute below command substituting required table and database:
  
  C:>"%plesk_dir%MySQLbinmysqlcheck" -P3306 -uadmin -p -r database_name table_name
  
  If the password is unknown, reset it according to this KB article.

Not all the storage engines in MySQL database support repair of the tables. If storage engine does not support repair the following message will appear:

The storage engine for the table doesn't support repair

In such a case, follow the instructions provided in the article: How to fix InnoDB corruption cases for the MySQL database?
