I used the whole disk as a PV. # pvcreate /dev/hdb and did create a volume group vgcreate vg_250GB /dev/hdb and 2 logical volumes lv_old_system with 50GB and lv_storage with the rest of the disk then I did copy all the data from the old harddisk to lv_old_system. With the Gentoo live CD I did then install gentoo linux to the old harddrive. The gentoo installer did delete the partitiontable on all connected harddrives :-( So my logicalvolumes are not available anymore. But vgchange shows that lv_old_system is somehow still available. Can you help me please, to recover that volume? As I did create the logical volume with the old SuSE 8 installation, which I did overwrite with the gentoo installation, I do not have the metadata backup in /etc :-( thinkpad ~ # vgchange -v -ay vg_250GB Using volume group(s) on command line Finding volume group "vg_250GB" Logical volume (lv_old_system) contains an incomplete mapping table. Wiping cache of LVM-capable devices Logical volume (lv_old_system) contains an incomplete mapping table. Volume group "vg_250GB" not found thinkpad ~ # Thank you in advance Thomas
