And add innodb_file_per_table to my.cnf file, of course.

It works when you:
* drop the foreign keys of the InnoDB tables
* alter the InnoDB tables to MyISAM
* stop mysql server
* remove/move the ibdata* and ib_logfile* files
* start mysql server (it should appear a new ibdata1 file with 10M filesize)
* alter the previously altered tables back to InnoDB
* create the foreign keys removed at the first step

@abul : yeah .. but why do u want to delete ibdata1 after step 3 and 4 ?

Step 1 and 2 will help you regain space … step 3 and 4 will help you optimize tables and have separate innodb files for them

Good Post. Thanks for the information. My question is, what will happen if we delete ibdata1 file after we do step 3 and 4? Could we regain the space again?
