Hi, I had to remove a hdd due to a hardware failure and tried to gain access to those LVs which did not use PEs on the broken disk. Therefore I perfomed the follfowing steps: 1) got LVM2.1.95.15 2) vgcfgbackup -P -f /tmp/backup.vg vg_ide 3) edited /tmp/backup as described here: http://lists.sistina.com/pipermail/linux-lvm/2003-January/013153.html with exception of a) there wasn't any PV section which was on the broken hdd so I had not to remove any and b) the segment sections of the LV which used the broken hdd did not contain an entry like 'pvX' inside 'stripes' but 'Missing' was entered. 4) vgcfgrestore -M1 -f /tmp/backup.vg vg_ide 5) vgscan ; vgchange -a y So far everything worked fine, when mounting the remaining LVs (only one had to be removed, the biggest one) this also works fine but when looking what the LVs contain they all contain the same: the contents of the smallest LV. mount shows for all LVs the same size, only device and mountpoint differ: /dev/vg_ide/lv_uml_rootfs 200M 137M 63M 69% /home/uml-rootfs /dev/vg_ide/lv_uml_swap 200M 137M 63M 69% /home/uml-swap /dev/vg_ide/lv_uml_log 200M 137M 63M 69% /home/uml-log lvdisplay shows the correct size: storage:~/lvm/sbin# lvdisplay /dev/vg_ide/lv_uml_rootfs --- Logical volume --- LV Name /dev/vg_ide/lv_uml_rootfs VG Name vg_ide LV Write Access read/write LV Status available LV # 2 # open 0 LV Size 3 GB Current LE 768 Allocated LE 768 Allocation next free Read ahead sectors 1024 Block device 58:0 storage:~/lvm/sbin# lvdisplay /dev/vg_ide/lv_uml_swap --- Logical volume --- LV Name /dev/vg_ide/lv_uml_swap VG Name vg_ide LV Write Access read/write LV Status available LV # 3 # open 0 LV Size 1 GB Current LE 256 Allocated LE 256 Allocation next free Read ahead sectors 1024 Block device 58:0 storage:~/lvm/sbin# lvdisplay /dev/vg_ide/lv_uml_log --- Logical volume --- LV Name /dev/vg_ide/lv_uml_log VG Name vg_ide LV Write Access read/write LV Status available LV # 4 # open 1 LV Size 200 MB Current LE 50 Allocated LE 50 Allocation next free Read ahead sectors 1024 Block device 58:0 System is Debian woody, Kernel 2.4.20 XFS patched LV's fs is reiserfs lvm tools version is 1.0.4 (woody-package) vgcfgbackup/vgcfgrestore is from LVM2.1.95.15 As I use LVM2.1.95.15 only for vgcfgbackup/vgcfgrestore, I use lvm1, I compiled the package with the configure --disable-devmapper option. I also tried to use vgscan and vgchange from the LVM2.1.95.15 package but it fails to activate the vm, vgscan seems to work and shows that it's an lvm1 VG but after running vgchange -a y there isn't any entry in /proc for the VG and of course the volumes can't be mounted. But I think that's due to missing kernel/module support for lvm2. Any hints how the get access to the content of all LVs?
