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 restart. Check this with the following command:
docker compose ps
docker-compose ps
Now exec the following commands:
Stop the stack, don't run "down"
docker compose stop
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
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.*
Execute a complete stack restart using the following commands:
docker compose down
docker compose up -d
docker-compose down
docker-compose up -d
