Hi Heikki,

Uhm ok nice trick. ;) Just for curiosity, where is the log sequence number stored, Header of Block, Extend, Segment?

However, I reimported all the stuff again and used the opportunity to reoganized the datafiles. The organisation of the datafiles within my.cnf is a bit inflexible, you can't even change the order of the datafiles without losing data integrity.

Now i use symlinks for the datafiles directories to separate the datafiles accross disks. Hope there is no drawback for Innodb with using symlinks.

Unfortunately mysql thinks these directories are in fact databases. ;)

innodb_data_home_dir = /www/mysql-data/
innodb_data_file_path = u01/ibdata01:10G;u02/ibdata02:10G;u03/ibdata03:10G;u04/i
bdata04:10G;u05/ibdata05:10G;u06/ibdata06:10G;u07/ibdata07:10G;u08/ibdata08:10G;
u09/ibdata09:10G;u10/ibdata10:10G

There is no way to put the innodb_logfiles on different disks, is it?

Regards,
Stefan
