[linux-lvm] Broken hard disk

[Martin Wilmes <martin wilmes java-cup de>]

Hi,

I had a standard Fedora Core 4 installation with the root fs and swap 
on LVM. I upgraded to Core 5. Everything worked fine. No need to be an LVM 
guru so far.

Then I added a new hard disk to the computer and a partition of this new disk 
to the root volume. The "new" hard disk then broke down so that I am unable 
to access the data on the root volume.

Now I installed the old, hopefully still working disk in a different computer 
and booted with Knoppix 5.0.1 to get some of my data back but vgscan -v comes 
back with nothing at all.

fdisk says

Disk /dev/hda: 20.5 GB, 20525137920 bytes
255 heads, 63 sectors/track, 2495 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1          13      104391   83  Linux
/dev/hda2              14        2495    19936665   8e  Linux LVM

Any suggestions how to recover that volume?

Thanks
Martin
