Sorry I missed that.

This information is stored mostly within the "partition" schemes. This makes
the system more prone to auto-detection.
Some configs are stored in /etc/mdadm and /etc/lvm, but in any case, when you
add a new HD already setup for RAID and/or LVM to your
non-RAID/non-LVMsystem, everything should be detected at boot time.
For LVM you should begin with pvscan, vgscan, and lvscan.
Question: I didn't get the part if you are installing RAID/LVM in a new
installation then cp'ing your *data*, or are migrating the full system to a
set of HDs with RAID/LVM. The second is more complicated, of course.
