Dunno whether my setup would work for you, but I've raid-5'd my disks,
then put a single lvm volume over the top, and then broken that up into
partitions as required.
Note that I didn't raid the entire disk, I left space for swap, boot. and /.
And I always plan to expand the array by doubling the size of the disks.
Effectively a raid-5+0 sort of thing. Add two double-size disks, raid-0
the disks I've removed and add them, and there's probably enough space
to resize onto those three before doubling up what's left and adding
that back.
(Note also I've got dm-integrity in there too, but that's me.)
