    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.
