We have found the command vgcfgrestore and we have him tested.
We have follow command used: vgcfgrestore -n vol0 /dev/hda4 and then comes this error:
vgcfgrestore -- ERROR "pv_read(): PV exported" reading physical volume "/dev/hda4"

Is the VG demaged ?

There's a hack to reactivate it in case you still have a valid VGDA backup, but let me first understand what your actual problem is, before we can decide to try that.
I guess he tried to move a disk to a new one by exporting the volume group, moving the data onto the new disk and importing that one. I guess the solution would be to import the volume group from the old disk (assuming the data is still available on it) and using pvcreate, vgextend and pvmove to get the data on the new disk, the use vgreduce to remove the pv of the old disk and remove it from the system.

Hello !
Yesterday, I have tested the export/import Funktion from LVM. I have exported the LVM, that has gone.

Do you mean you successfully run "vgexport VGName" on your deactivated VG named "VGName"?

In the next step I would import the LVM on a other disk.
What do you mean with "other disk"?
The vgimport(8) command has the synopsis:
vgimport VGName PhysicalVolumePath [PhysicalVolumePath...]
If you exported the VG just to test the feature as you mentioned, you should run pvscan which should list you all of the physical volume pathes belonging to the exported VG and feed those pathes into vgimport.
See "man vgimport" for further details.

The LVM has not imported the LVM on a other disc, becaus I became a Failure.
What was the failure message?

My question, can I make a un-export on the old-disk?
No, you can just import it.

This doesn't necessarily imply that your VG is damaged.

vgcfgrestore recognized that /dev/hda4 belongs to an exported VG and therefore it complained.

If Torsten's guess below is right: if you copied the PV content to a different disk (of the same size!) there was no need to export the VG in the first place.

You didn't mention if you tried Torsten's hints in case his assumption was right.

My general problem is, that you didn't provide more information, as I requested in my first answer to your e-mail, in order to *really* understand for sure what your situation is and which steps you made to get there.

So input like:

- what was the starting configuration *before* you changed something?
- what was the configuration change you wnated to achive?
- what where the commands you run in sequence to get there?

would be appreciated in order to help you at all.

Could you at least provide the following outputs to get a little more light into this:

- "pvscan"
- "vgscan -d"
- "vgdisplay -Dv"
- "ls -l /etc/lvmconf"
