pre-create innodb tablespace

[Gary Richardson]

Hi,

Can I pre-create innodb tablespace using something like dd (or any other
better tool)?

I have a server that is getting low on innodb table space and I want to add
15GB or so, but I want to minimize downtime. The server is a bit slow and I
estimate it will take around 10-20 minutes or so. I was hoping to 'dd' the
additional table files, add the configuration directives to my.cnf and
restart the server. This would mean my downtime would be whatever time it
takes to restart the server.

Thanks.
