Hi!

I'm running a core Linux system with the 2.4.17 kernel. The current computer 
behind this was an AMD K6 300 with 128 MB RAM and a Tecram DC390 SCSI 
Controler. On this sytem I had 3 IDE HD's with at least 2 lvm Volume groups 
and 2 Logical Volumes.

Now I had to reduce on of the three IDE HD's. On this HD was no LVM on, but 
"/". So I reduce my 2 LV to only on partition and use the other for "/". I 
change to Singel User mod and copy the wohl data to that Partition.

After I reboot everythin works fine only the Volumegroups couldn't be 
activated any more.

I tried several of the LVM tools on a copy of this disc but nothing helps. 

With pvdata I can the all meta data of the Volume Groups and of the Logical 
Volumes but I can not access to them any more.

Here some details:

When I search for this error on your webside I found a hit to take the LVM 
1.1-rc2. So I upgraded but the error still came. 

Can you help me?
