[CentOS] Copying root partition

I recently transferred the / partition on my CentOS server
from a small disk to a large disk, using "rsync -auvz".

This works fine, except that I get dozens of selinux warnings
when I re-boot.
I'm running selinux in permissive mode.

Is there any way to make sure that all the files in a partition
are kosher as far as selinux is concerned?
