Adding an extra disk to an existing LVM volume group isn't a problem, it's one 
of its features actually.

Adding an extra disk to an existig raid array might or might not be possible. 
This depends on the capabilities of your raid controller. It's possible for 
instance with linux' software raid, but the tools required are far from 
production ready. Cheaper raid cards most likely won't offer this feature.
