Subject: LVM over MD on 2.3.x

Since RAID 1/5 has finally been included in 2.3,
I can not try to get my setup working under 2.3. I have run into a problem with getting LVM working over RAID5. This works under 2.2.x, with LVM 0.8i and RAID 0.90, but with 2.3.99pre8, it doesn't work. I can get vgscan to find the VGs, and I can get vgchange to activate them (with a small hack to the source, anyway), but the kernel driver has problems. Any access to an LV returns the contents of md0. It looks like the LVM driver isn't remapping blocks when used over raid.
I remember Andrea Arcangeli posting to the
linux-kernel list about stacking block drivers and saying something about this, but I can't find the post.
Any idea what's going wrong and what I can do
fix it?
