title: Can't optimize innoDB table
body: <p>As my first message here, i don't know if i have to answer or post a new message.
  I have the same problem as <a href="https://stackoverflow.com/questions/2816044/optimize-innodb-table">here</a> and the one and only given answer doesn't help me (except if the documentation is incorrect).
  "You can make OPTIMIZE TABLE work on other storage engines", but my engine is InnoDB.
  I thank you for your help.
