[LAU] HOWTO, AVLinux --> LVM?

OK, I am officially intrigued :-) My focus is live; I do recording
sometimes on laptops and then immediately copy it elsewhere, but my
primary is a desktop box set up for transportability with two laptop
hard drives, running ZynAddSubFX (Yoshimi from now on I think) and
Qsynth as MIDI module with my keyboard. I have a third desktop hard
drive installed also, not being used, as an aid to moving it all to
RAID-1 which has seemed likely. But now I understand positively that
LVM drive mirroring is an option. A few questions:

1. What are the advantages of LVM drive mirroring over RAID-1? I
understand that one advantage is mdadm update issues; I have had a
machine hosed this way too. Are there other advantages?

2. If I set up LVM drive mirroring, can I boot off either drive?

3. How do I set up LVM drive mirroring?

4. If I set up LVM drive mirroring and take a drive out, can I put that
drive in another machine and expect it to boot?

J.E.B.
