Another poster mentioned LVM as a possible solution. I have used LVM
under AIX on the rs6000 servers, but never under linux. If it works
similarly you will need to put both the drives in a volume group and
then define a logical volume using both physical drives as the /
partiton and it would work very well
Maybe someone else can give you the details for this
