Not really the answer I wanted. I assumed that the default was for LVM
to stripe and by adding bot disks to the volume group before migrating
it of the physical extent I would be OK. I migrations can loose stripe
then surely that is an issue?

The Volume was created as part of a xen server virtual machine install
so I have limited control over initial LV creation parameters.
