[Pkg-cryptsetup-devel] Bug#382450: Root on (lvm-)crypto-md doesn't work

Fri Aug 11 05:23:48 UTC 2006

Package: cryptsetup
Version: 1.0.3-3

I'm interested in running an encrypted root partition, specifically
where root is a logical volume on dm-crypt on raid1 md.  The nightly
build of the Debian installer (2006-08-09) is willing to build this
setup without complaint.  However, when booting into the new system, the
cryptroot script fails to properly open the encrypted md partition.

Here's the system layout since it's a little confusing:

/dev/hda2, /dev/hda3        => /dev/md0           (raid1) (testing only)
/dev/md0                    => /dev/mapper/crypt0 (dm-crypt)
/dev/mapper/crypt0          => ep.root            (volume group)
/dev/mapper/ep.root-ep.root => /                  (jfs formatted logical volume)

I've read through some of the other bug reports (#371846 and others) and
there seems to be some discussion on properly determining device
dependencies, but as far as I can tell a general solution hasn't been
developed yet.  Is this the right answer?  Or is it possible to hack md
support into cryptroot as was done for lvm?

Here's a console dump of the machine attempting to boot for the first
time, the bottom four lines repeat indefinitely:
