No, not at all. This is actually the recommended wayx to restore a messy VG ;-)
You need to run "pvcreate -ff" on all of the (former) PVs and vgcfgrestore on
each of them afterwards.
Could you save your VG's metadata before by running
for PV in YOurPVs
do dd if=/dev/$PV of=VGDA.${VGName}.$PV bs=1k count=512
done
and storing the copies on tape or something so that we are able to backup
for potential further investigation?
