It usually doesn't make sense to split a disk in smaller partitions and RAID them togheter. If the whole disk dies, you loose two partitions and your whole RAID-array. The software raid implementation in linux doesn't allow you to add more disks to an existing array, but of course you can delete your array and create a new one with more disks. Some hardware raid implementations (and possible some software-raid implementations too) allow you to add more drives without redoing the array. --=20 Ragnar Kj=EF=BF=BDrstad Big Storage
