For people, who are as click and point-lazy as me, here is how you restart the service without using the service management applet.

net stop "NSClientpp (Nagios) 0.3.5.2 2008-09-24 w32" net start "NSClientpp (Nagios) 0.3.5.2 2008-09-24 w32" |
Well, since I had to brood about this (again I might add), I’m gonna write it down this time …
Setting up the InnoDB raw device isn’t that hard, just make sure the device has proper permissions (either add mysql to the disk group or create a udev rule).

KERNEL="sdb2", OWNER="mysql", GROUP="mysql" |
Now after that (and a reboot/udevcontrol reload_rules later), you should be able to initialize the InnoDB device. Yes, the InnoDB device needs initializing.
When you create a new data file, you must put the keyword newraw immediately after the data file size in innodb_data_file_path.
The next time you start the server, InnoDB notices the newraw keyword and initializes the new partition.
After that is done, you should be able to start the MySQL service for the first time. It is gonna fail (at least according to the init-script), but ultimatly if you take a closer look at /var/log/mysqld.log it’s gonna be successful.

After that, remove the “newraw” from your /etc/my.cnf. Otherwise, MySQL is gonna reinitialize the volume all over again, as the handbook states.
However, do not create or change any InnoDB tables yet. Otherwise, when you next restart the server, InnoDB reinitializes the partition and your changes are lost.
After InnoDB has initialized the new partition, stop the server, change newraw in the data file specification to raw.
