You're making an assumption that wouldn't hold on most of my machines (event though they're not converted to pve yet). - I often have SSD and HDD based physical volumes in a volume group, so I can decide which LV I put on which PV - speed vs space - Huge drives - esp. HDD based ones, I usually partition to get smaller PVs (each partition a PV) for 2 reasons: 1) the PVs at the beginning of the disk are usually faster than the ones at the end - this makes it easier to place a LV 2) Handling of PVs (think about pvmove) is easier. This might or might not be of interest for the regular pve user (and I guess I'll end up hand-optimizing for my setup anyway when using pve ;) ) but I don't think automatic striping by default, just based on the number of PVs is a good idea.
