I don't know how that second metadata area got there :) I don't think I'm using it or will have any use for it. So there is no way of erasing it? If I do "backup VG, redo pvcreate with uuid& restorefile, restore VG" as Alasdair said as quoted by malahal@us.ibm.com, I will erase all data, right? The solution seems to be roughly equivalent to backing up all data and then repartition before copying back?
