Hi, When we changed the physical position of the harddrives we were able to mount the existing volumegroup. When we rechanged these drives to the original position and tried to activate the volume group with vhchange -a y we got the following error: vgchange -ay vgchange -- ERROR "Bad address" activating volume group "lvmgroup1" . vm -- _pv_get_number failed for rdev = 65535 lvm -- lvm_snapshot_fill_COW_page failed (I tried: lvscan -D vgscan vgchange -a y) Do you have any suggestions?
