Did you try with USE_LAYOUT=y in your local.conf?

That option, now enabled by default in the snapshots, should provide
you with some way to do it. It guides you through the layout creation
process if any anomalies are detected. It currently resizes partitions
used by LVM and software raid. It does not currently resize normal
partitions, but that is open for discussion.
