Striping doesn't work that way. It stripes across all pvs EVENLY to improve access speeds (the whole reason to stripe). The only way to do what you want would have been to use kernel RAID to combine the physical devices into a single logical device before creating the stripe set. > I would create a new lv as you suggested, but drives a and c are two > times bigger than b and d, so I thought about the above solution. I understand, I went through the same exercise two months ago. I borrowed a disk from a friend, moved all of the data to it, and rebuilt my whole VG setup. It was a major pain in the neck.
