Thank you, Roger. I might be able to do that on the original machine, which won't boot at the moment because of this failure, but I have been using a working machine so far to use ddrestore etc. Yes, as you said, I was able to use dd to copy off the vgconfig data into a file. So you think that I might be able to use that as the reference in pvcreate? That makes some sense. I started this out asking ( but not clearly ) whether the data on the disk appeared to be in the correct place and whether what was there was correct, but I think that I answered that for myself with the comparison to the working PV partition.
