Unfortunatly, I don't have any data for vgcfgrestore to build upon. Here's the current status: /dev/loop0 is pointing to /root/lvm/hde1 /dev/loop1 is pointing to /root/lvm/hdf1 (built via 'dd if=/dev/hd?1 of=/root/lvm/hd?1') /dev/loop0 is the good image /dev/loop1 is the fubar'd one. pvdisplay /dev/loop0: --- PV Name /dev/loop0 VG Name data PV Size 14.31 GB [30009357 secs] / NOT usable 1.01 MB [LVM: 135 KB] PV# 2 PV Status available Allocatable yes (but full) Cur LV 1 PE Size (KByte) 4096 Total PE 3663 Free PE 0 Allocated PE 3663 PV UUID 3IRYim-Lpgb-2N1Y-6TPu-C8mZ-58hy-exlmBm --- pvdisplay /dev/loop1: --- PV Name /dev/loop1 VG Name data PV Size 9.44 GB [19792017 secs] / NOT usable 4.07 MB [LVM: 130 KB] PV# 1 PV Status available Allocatable yes (but full) Cur LV 1 PE Size (KByte) 4096 Total PE 2415 Free PE 0 Allocated PE 2415 PV UUID P7xAxa-J36q-2C8i-2vKc-5KJO-2tQ6-H3eGiz --- First I tried running pvscan: --- pvscan -- reading all physical volumes (this may take a while...) pvscan -- inactive PV "/dev/loop0" is associated to unknown VG "data" (run vgscan) pvscan -- inactive PV "/dev/loop1" is associated to unknown VG "data" (run vgscan) pvscan -- total: 2 [23.75 GB] / in use: 2 [23.75 GB] / in no VG: 0 [0] --- fair enough.. so I run vgscan -v: --- vgscan -- removing "/etc/lvmtab" and "/etc/lvmtab.d" vgscan -- creating empty "/etc/lvmtab" and "/etc/lvmtab.d" vgscan -- reading all physical volumes (this may take a while...) vgscan -- scanning for all active volume group(s) first vgscan -- reading data of volume group "data" from physical volume(s) vgscan -- ERROR "vg_read_with_pv_and_lv(): current PV" can't get data of volume group "data" from physical volume(s) vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created vgscan -- WARNING: This program does not do a VGDA backup of your volume group --- ofcourse /etc/lvmtab and /etc/lvmtab.d/* are all blank/empty. If anything, I'm just about at the point where the dead drive is a writeoff (/dev/loop1).. but I would like to try to salvage the data on /dev/loop0 Any ideas?
