Problem with ibdata1 (trying to convert to MyISAM)

[John Cubillos Vega]

Hi.
I have a problem in a database for a couple of tables that use InnoDB.
Precisely because of this, I want to convert them to MyISAM executing this query:

alter table TABLE_NAME engine MyISAM;

The problem is, that in the execution the file ibdata1 is still growing to the point that the partition fill up and kill MySql.


I also tried adding a second ibdata to another partition with enough space and although it does create the second file, Mysql does not get to use it but still fills up the disk by growing the original ibdata1 file.

What can I do?
