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, Andy
