[linux-lvm] Major Problems with my damaged LVM! Please Help! :-)

[Sebastian Kindt]

Hello,

I have a major Problem. First my initial situation:
I have a Fedora Core 3 System with one harddrive an the standard LVm Settings on it. Then the disk was full an I added a second harddrive and included it in the Volume Group. But I never enhanced the filesystem. So the second Harddisk was always empty. Then I set up a new System an put the empty HD from the old System in it. But I forget to remove the Disk from the VG of the old System. Now the old system doesn't boot up because the second hard drive is missing.
What are my possibillities to get the Data from this Harddisk back? At the Moment I have this disk in a system where the system is on a standard ext3 filesystem.

Please help me because the data on the disk is very important..

With best regards..

Now a few outputs:

fdisk /dev/hdd (The defect Harddisk)
