I originally setup the system with the following steps: - vgscan vgscan -- reading all physical volumes (this may take a while...) vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created vgscan -- WARNING: This program does not do a VGDA backup of your volume group - pvcreate /dev/sda2 ; pvcreate /dev/sdb1; pvcreate /dev/sdc2; pvcreate /dev/sdd2 - vgcreate vg01 /dev/sda2 /dev/sdb1 /dev/sdc2 /dev/sdd2 - check no of LE pvdata -E /dev/sdc2 (5710 LE) lvcreate -l 5711 -n lv03 vg01 /dev/sdc2 - Make ext3 fs on each LV mkfs.ext3 /dev/vg01/lv01 /dev/sda2 and /dev/sdb1 are kaput (both drives died within days of eachother). I believe I had 4 logical volumes. /dev/vg01/lv01 /dev/vg01/lv02 /dev/vg01/lv03 /dev/vg01/lv04 in my volume group. So I presume this means each LV resided on a separate drive and probably lv01 and lv02 were the 2 on the 2 dead disk drives. * PVs on four SCSI devices * A VG called "vg01" comprised of said PVs If I reinstall lvm on my newly installed system can I recover lv03 and lv04? I have had a search and see something called importvg which I think may be what I need. Had anyone ever had any experience recovering a volume group with missing disks? I have backups of my lvm config but it seems like lvmtab etc are all binary files, are they of any use to me? Many Thanks, melinda
