Suite à une coupure de courant, mon PC qui me sert de serveur n’a pas pû remonter correctement son filesystem et ce dernier est passé en lecture seule…
Après un fsck du sdb1 endommagé, j’ai eu l’erreur suivante sur le démarrage de Mysql :

/root@arcadia:~# /etc/init.d/mysql restart
Stopping MySQL database server: mysqld.
Starting MySQL database server: mysqld.
Checking for corrupt, not cleanly closed and upgrade needing tables..
root@arcadia:~# ERROR 1577 (HY000) at line 1: Cannot proceed because system tabl es used by Event Scheduler were found damaged at server start
ERROR 1547 (HY000) at line 1: Column count of mysql.proc is wrong. Expected 20, found 16. The table is probably corrupted

Une rapide recherche sur Internet m’a donné la solution et la possibilité de mettre un nouvel article sur ce site vide 🙂
