After some troubles with MYSQL server I made a backup for my databases and reinstalled MYSQL server with plesk parallel panel. I wanted to restore the old backup content in /var/lib/mysql/ and some how I droped the psa table, and now once I try to access parallels with my browser i recieve this message: internal error. ERROR: PleskFatalException: Unable to connect to database: Unknown database 'psa' (auth.php:149) What I know now is that I have dropped psa database and I have to retore it from the backup of the new mysql installation typing this command ls -la /var/lib/psa/dumps/ shows me that I have a compressed backup for my database mysql.daily.dump.0.gz I dont know what this compressed file do contain I mean is that only my psa database or there is others databases, and how to restore only psa database under /var/lib/mysql Edit I found this solution: zcat /var/lib/psa/dumps/mysql.preupgrade.
