MySQL doesn't work. I tried to modified the line: innodb_data_file_path = ibdata1:10M:autoextend
to innodb_data_file_path = ibdata1:500M or innodb_data_file_path = ibdata1:500M:autoextend or innodb_data_file_path = ibdata1:500M;ibdata2:1000M:autoextend they all gave me the same error below. InnoDB: Error: data file ./ibdata1 is of a different size InnoDB: than specified in the .cnf file! InnoDB: Could not open data files 031105 9:42:56 Can't init databases 031105 09:42:56 mysqld ended The last one really does the matter!! That's if I run out of the space on the current directory, I won't be able to put another file anywhere else!?
