What is after:

Code:
200601 12:48:19 [ERROR] InnoDB: File (unknown): 'read' returned OS error 71. Cannot continue operation
I assume you're getting this from the error log?


Ultimately though, this is something that you or your database administrator will need to fix, but we can certainly try advising you on how to correct this yourself with some guidance if you'd like.

You may want to increment "innodb_force_recovery" from 1 to 2 (if you're unable to start MySQL) and so on in the server's MySQL configuration at /etc/my.cnf, restarting MySQL each step along the way in an effort to repair the corruption InnoDB is encountering when it starts up. If you are familiar with the Linux command line, the following guide is quite helpful and extremely detailed for database restoration and repairing InnoDB:


If you're uncomfortable with this, you may wish to contact a qualified database administrator and may find one to consult with at the following:
