When you say "running BTRFS raid1 on top of LVM RAID0 volumes" do you

Yes, although it doesn't have to be LVM, it could just as easily be MD
or even hardware RAID (I just prefer LVM for the flexibility it offers).
A quick tip regarding this, it seems to get the best performance if the
stripe size (the -I option for lvcreate) is chosen so that it either
matches the BTRFS block size, or such that each block in BTRFS gets
striped across all the disks.
