I wonder if I could boot off a Ubuntu CD or something and grow the array that way.

Well, it _is_... the old array was 4*500Gb. The new array is 5*1Tb. In each I've built a single VG/LV. But my machine can't handle 9 SATA disks (power, controller limitations, space). So what I did was use one of the TByte disks to copy the data, built the other 4 into an array, copied the data from the last disk onto the array and then... failed to extend the array. I still have the old 4*500GB on a shelf, but I don't have anything I can plug it into. (My other option is to buy a couple of SATA controllers, build a second machine then transfer data over the network) -- rgds Stephen
