Pascal,
can you send me (hjm@redhat.com) the first 4MB (see script below) of each PV
and I'll try to reconstruct your partial overwritten metadata.
Regards,
Heinz -- The LVM Guy --
I need the dd output of /dev/hda[156]:
for d in 1 5 6
do
dd if=/dev/hda$d of=hda${d}.vgda bs=1k count=4k
done
tar cf pascal.vgda.tar hda?.vgda
rm hda?.vgda
bzip2 pascal.vgda.tar
