[linux-lvm] LVM2 on dmraid -- can't boot

[David Abrahams]

When building the new system installation from a liveCD, I can easily
create an LVM2 filesystem on top of a dmraid (FakeRaid) 1 array, and
the filesystem works great.  However, when booting from a primary
physical (non-LVM) partition on the dmraid array, only that partition
seems to mount properly; When I try to mount any of the LVM
partitions, all I see in them is "lost+found."  Naturally, the boot
process fails at that point.

http://article.gmane.org/gmane.linux.ataraid/1989
illustrates my situation.

The two details not mentioned there:

1. When mounting any partition (LVM or not), I get 'cramfs: wrong magic'

2. I see the following when I do dmraid -ay

    [ 2881.836361] attempt to access beyond end of device
    [ 2881.836406] sda: rw=0, want=9767777280, limit=876773168
    [ 2881.836361] attempt to access beyond end of device
    [ 2881.836406] sdb: rw=0, want=9767777280, limit=876773168

Can anyone offer help?
Thanks!
