Same (but different) idea here, I'd hate to waste a 250GB for a spare. :-)

I still have one LVM issue to figure out, they say that you should set the 
partition type to 0x8e, but I can't find if that applies to md devices too. 
And if it does how do you set that. Running 'fdisk /dev/mdx' ?  Well, why not 
I suppose, but I've never ran fdisk on an md device, only mkfs.*

Thanks Guy,
Maarten
