Hi Alan,

Thanks very much for your reply.
Lets take this back to the list - not keep it between us - and I am subscribed to the list so no need to copy me.

You don't include the one piece of information that shows that the volume group sits on the raid device.

Can you do either pvdisplay, or vgdisplay -v

Does it show the volume group sitting on raid device


It appears to me to be showing the volume group sitting on the raid device. Any ideas what the problem might me?
I don't know. When I have had a problem before, I have just repartioned the old/new device and add these partitions using mdadm 

It then syncs up (albeit over several hours).
I don't format it or put filesystems on it - which I think your original mail mentioned.
