William, When you defined lvol00, did you make it a striped volume? That can cause the problem you're seeing.

I've tried to follow the documentation shown at http://www.sistina.com/lvm_howtos/lvm_howto/Common_tasks.html and (loosely) http://www.sistina.com/lvm_howtos/lvm_howto/Add_a_new_disk_to_a_multi.html but I'm having trouble getting lvextend to work. If anyone has succeeded in accomplishing this themselves, would you review my actions and see if I've missed a step?
