MariaDB: Aria recovery after crash¶

If your server crashed and MariaDB logs an error similar to [ERROR] mysqld: Aria recovery failed. Please run aria_chk -r on all Aria tables (*.MAI) and delete all aria_log.######## files you may want to try the following to recover the database to a healthy state:

Start the stack and wait until mysql-mailcow begins to report a restarting state. Check by running docker-compose ps.

Now run the following commands:

```

Stop the stack, don't run "down"¶

docker-compose stop

Run a bash in the stopped container as user mysql¶

docker-compose run --rm --entrypoint '/bin/sh -c "gosu mysql bash"' mysql-mailcow

cd to the SQL data directory¶

cd /var/lib/mysql

Run aria_chk¶

aria_chk --check --force /.MAI

Delete aria log files¶

rm aria_log.* ```

Now run docker-compose down followed by docker-compose up -d.
