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.
