So I posted this info in general support and eagerly awaited a reply, but 5 days later not a single hit. I'm moving this question here in hopes of finding a pro in the security area, which is really matters here.
For reference this is the original post:

First off, this is a general linux question that I'm applying to Fedora 8 and Fedora 9, since those are the flavors-at-hand with my actual computer in question. If someone thinks there is a better list, or just another, that this topic should be on, just let me know.
On to the question...
I have what I assume is a fairly common question: How do you properly convert from "normal" disk and partition usage to an LVM and encrypted disk setup while increasing overall storage and without moving existing data to a temporary location? If at all possible I'd like to keep all the software necessary to do this within the standard Fedora yum repositories (i.e. no sourcecode installations or other repos like Livna/ATRPMs being necessary). I have nothing against other repos or source, but I think this is the kind of stuff that should be solvable within mainline Fedora itself.
(a) Specifically I have the following: A Fedora 8 host with two physical disks: one for all my OS related partitions and home drives, and a SATA drive with a single primary partition. The SATA drive is formatted with JFS at the moment, and is about 95% full with data (media from my mythtv, actually). I have a second completely unused identical SATA drive ready to be used in the same host. Both SATA data drives are 750gb drives. Not that it should matter, but I have a x86_64 bit Intel based system.
(b) I'd like to get to the following: I'd like to keep my main disk and operating system as-is. I'd like to have my twin SATA disks setup as a single logical volume that is encrypted with something like LUKS. I'd expect to be prompted for a single password during my boot process in order to properly mount a single, logical, 1.5TB encrypted partition.
I'd also like to be able to get from point (a) to (b) without the need for external storage.
I'm aware that Fedora 9's imminent release should vastly improve encrypted filesystem tools. I'm also aware of Fedora's affinity for LVM stuff, but despite that I've never actually used it.
So how would I go about accomplishing my changes? Is this the kind of thing that is easy and possible via some GUI in Fedora 9? Should it be?
