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?
