Sounds good but I really do wonder if he has a hardware raid controller that does not support resizing of Linux LVM on top of the HW Raid Volume Set?? No one asked that part.
Surely if the Volume group has unallocated space extending the LV should not be a problem since it is not altering things as seen at the raid controller level. Or am I missing something?
Yes, the LVM layer is distinct from the raid level. In some other OSes it is more tightly integrated (bound, coupled, mashed together). It is possible, I suppose, that if the underlying physical volume is backed by an over-commited, data deduped device then resizing an LVM inside a VG could cause issues though :D..
