The trick to getting it all to work together is doing the raid setup

I did something similar here. By creating the RAID first, you only
need
to RAID one large partition.
Is there a performance hit with lvm on RAID vs. just plain RAID?
you'd have to define "just plain raid". There is a performance
penalty for software raid over hardware raid, but I've not been able
to see any performance penalty for lvm over plain filesystem. Note
that my testing has been on light-to-moderately loaded systems, not
heavily io-based.
