My problem is that I accidentally left my LVM disks in my system when I
installed windows XP On a seperate drive. I did not install windows to
either of the LVM's so that should not be an issue.
However when I replaced my linux drive, and booted into linux, I got the
following error when my system tried to start up LVM
(for vgchange -ay)
mog root # vgchange -ay
2 logical volume(s) in volume group "vg0" now active
Logical volume (lv0) contains an incomplete mapping table
Unable to find volume group "vg_samsung"
vg0 is my other lvm which thankfully is still there.
now, whenever I do any of the 'scan' tools (vgscan, pvscan, lvscan) I get the
following errors:
vgscan:
...
Logical volume (lv0) contains an incomplete mapping table
Unable to find volume group "vg_samsung"
pvscan:
Logical volume (lv0) contains an incomplete mapping table
...
lvscan:
...
Logical volume (lv0) contains an incomplete mapping table
Unable to find volume group "vg_samsung"
however, if I do pvdisplay on my 2 drives I get some info
mog root # pvdisplay /dev/hde <--my 160gig drive, I think the second drive
in the LVM
- --- NEW Physical volume ---
PV Name /dev/hde
VG Name /vg_samsung
PV Size 19.84 MB
Allocatable NO
PE Size (K..) 0
Total PE 0
Free PE 0
Allocated PE 0
PV UUID fXhdbW-S1KK-lSNs-kGSQ-dsb6-9Kkn-Q7xeTk
That looks bad to me, but the first drive in the volume looks ok:
mog root # pvdisplay /dev/hdg <--my 80gig drive
- --- Physical volume ---
PV Name /dev/hdg
VG Name /vg_samsung
PV Size 74.56 GB / not usable 31.57 MB
Allocatable yes (but full)
PE Size (K..) 16384
Total PE 4770
Free PE 0
Allocated PE 4770
PV UUID aE0Tfs-UX8r-oTma-Eo35-mxSg-ZT5w-ZHPPTW
so it looks like windows only blasted the second of the two drives (which
came first in the bios) (or the
first one it found?)
I am desperate to get this data back (and unfortunately my /etc/lvm/backup or
archive are empty :(
Thankyou very much in advance!
