@ -421,7 +421,7 @@ rule 'Max InnoDB log size' [innodb_buffer_pool_size > 0 && innodb_log_file_size
innodb_log_file_size / (1024 * 1024)
value >= 128
The InnoDB log file size is inadequately large.
It is usually sufficient to set innodb_log_file_size to 25% of the size of {innodb_buffer_pool_size}. A very innodb_log_file_size slows down the recovery time after a database crash considerably. See also <a href="http://www.mysqlperformanceblog.com/2006/07/03/choosing-proper-innodb_log_file_size/">this Article</a>. You need to shutdown the server, remove the InnoDB log files, set the new value in my.cnf, start the server, then check the error logs if everything went fine.
