Hmm yes as you say I think I could just make another partition in
the empty space, RAID-1 that, put a PV on the new MD device and then
vgextend onto it I suppose.  It just seems a litlle messy though to
needlessly have the extra partitions and if I can fix it before the
machine is put in production then I feel like I probably should.

Cheers,
