You can do the extra drive thing, but I've always done it with the existing
drives in the machine. Starting with an existing machine, which you want to
RAIDise [1]...
* Set up your raidtab normally, for whichever level you care about (in
this case, 1)
* Set the disk that has data on it (let's call it 'master') to 'failed'.
This allows you to explicitly remove it from the RAID array whilst
you're setting it up.
* Use (c)fdisk to set all of the partitions to the RAID autodetect type.
* Start RAID, initialise the array, and format it.
* Mount the array and copy everything over from the 'master' disk (cp -a
will do it properly).
* Now you can check that it boots on RAID and does everything normally.
* If it breaks, you can easily boot back in to the 'master' and fix stuff.
* If it works, you can switch 'master' back to a raid-disk and hotadd it.
It will sync, and your RAID array will be running at 100%.

installer's RAID stuff.
