My current setup: Root on LVM2, Kernel 2.6.12. I remember I had to
arm-twist the initrd-generation to get it going, way back.
The root fs is on LVM2:
andr...@kauz:/tmp$ LANG=C df /
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/e2vg/root 15482320 10793140 3902748 74% /
The twist in this setup: This root block device is a symbolic link:
andr...@kauz:/tmp$ ssh r...@localhost LANG=C ls -l /dev/e2vg/root
lrwxrwxrwx 1 root root 21 Jul 15 11:35 /dev/e2vg/root -> /dev/mapper/e2vg-root
Today, I was trying to upgrade to kernel 2.6.16. The update itself went
smoothly enought, but I could not boot into the new kernel with the ram
disk that had been produced automatically. Appearently, the ram disk
generation scripts did not find out that /dev/e2vg/root lives on LVM2.
Here is the long story:
Looking at the ramdisk contents with
gunzip < /boot/initrd.img-2.6.16-2-k7 | cpio -ivt
I saw that not a whole lot of LVM things were included.
I tried this and that. In the end, I hacked update-initramfs itself,
adding "-r /dev/mapper/e2vg-root" to the mkinitramfs - call:
kauz:/usr/sbin# diff -u update-initramfs-ori update-initramfs
- --- update-initramfs-ori 2006-07-15 11:54:55.000000000 +0200
+++ update-initramfs 2006-07-15 11:58:37.000000000 +0200

"${version}"; then
set_sha1
else
mkinitramfs_return="$?"
That produced a rd that did contain more of the LVM stuff.
I then changed the new kernel line in /boot/grub/menu.lst
from root=/dev/e2vg/root to root=/dev/mapper/e2vg-root
kernel /vmlinuz-2.6.16-2-k7 root=/dev/mapper/e2vg-root apm=off
Now, it all worked.
Regards, and thank you for providing fine software,
Andreas Krüger

closing as bug is not really about initramfs,
but more a lvm2 pecularity.
workaround to use real device aka /dev/mapper/vg-lv is easy
and recommend. it is the one that debian-installer uses.
thanks for report
