For What It's Worth. (FWIW... I don't use too many IM/list-speak
acronyms and tend to dislike reading posts from those that do, but I use
a few common ones, FWIW, BTW=By The Way, smilies, etc.)

I've never done that, tho I understand it's workable if you have
/boot separate and an initramfs/initrd with lvm2 therein, but I spent
QUITE some time planning my system so it wasn't necessary, putting
root and rootbak (if one fails I can boot the other, I update the backup
only periodically, when I know the main one is working well) on
partitioned RAID-6, specifically to AVOID root on lvm. Unlike lvm, the
kernel can pickup md/RAID parameters from its command line and can boot
into it directly, so that's how I have it arranged, /boot on RAID-1 as
that's all the RAID grub can handle, root and rootbak, along with the
physical volume for my LVM for everything else redundancy critical on
partitioned RAID-6, and 4-way striped swap and RAID-0 for caches (ccache,
the Gentoo tree, /usr/src/linux/) that are speed but not redundancy
critical.
The root and rootbak partitions contain most of /usr and /var as well,
basically everything that gets touched by ebuilds and the package manager
including its data, so it all stays in sync. If I were doing it over,
the only two things I'd do differently would be to have two rootbaks, so
if the system crashed while I was writing the one backup and neither it
nor the primary working root were functional, I could still boot the
other backup, and I'd create my RAID using at least 5 spindles/drives
(but go lower end on capacity per spindle), as writing to a 4-way RAID-6
is slowwwww.
