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"
