Thanks for responding. vgck seems to say that things are alright: # vgck /dev/vg00 vgck -- VGDA of "vg00" in lvmtab is consistent vgck -- VGDA of "vg00" on physical volume is consistent I also did try to restore all of the old metadata backups, but to no avail. Do you have any other suggestions? I still do not understand why vgcfgrestore say that the sizes are different, since I did a block-by-block copy from the original partition. Thank you again for your help. On Fri, Apr 25, 2003 at 11:21:24AM +0200, Heinz J .
