Emanuel, IIRC from your other mail, you had the out-of-sequence number problem fixed with your PV numbers (recent LVM1 CVS contains a fix for this already) and have your VG back, right?

"pvdata -PP" gives you offset onfo such as: <SNIP> pv_on_disk.base 0 pv_on_disk.size 1024 vg_on_disk.base 1024 vg_on_disk.size 5120 pv_uuidlist_on_disk.base 6144 pv_uuidlist_on_disk.size 32896 lv_on_disk.base 39040 lv_on_disk.size 10824 pe_on_disk.base 53248 pe_on_disk.size 4259840 The definitions of the various structures and tables are in lvm.h (pv_disk_t, vg_disk_t etc.).
