Hello,
I need some help from LVM/LUKS/initramfs/boot-experts because my server does not boot after upgrading from 2.6.31 to 2.6.32 - using the same kernel-.config!
My athlon2-gentoo-amd64-server has one 500GB SATA drive
| Code: |
Device Boot Start End Blocks Id System
/dev/sda1 1 13 104391 83 Linux

attached to an onboard 00:14.1 IDE interface: ATI Technologies Inc SB700/SB800 IDE Controller. Sda1 ist just the ext2-bootpartition, while sda2 is LUKS-encrypted and contains

Long ago, I created the 2.6.31 kernel using genkernel. Then I emerged 2.6.32, copied the .config from 2.6.31, ran "make oldconfig" and used | Code: | | genkernel --no-menuconfig --oldconfig --install --makeopts=-j5 --lvm --luks --disklabel all |
(also tried many other settings) to create the new 2.6.32 kernel. It installed fine.
This is my kernel configuration: https://politbuero.dyndns.org/2.6.32-kernelconfig.txt
This is my grub.conf:
| Code: | title=Gentoo Linux (2.6.32-gentoo)
root (hd0,0)
kernel /boot/kernel-genkernel-x86_64-2.6.32-gentoo-r1 root=/dev/ram0 crypt_root=/dev/sda2 real_root=/dev/vg/slash dolvm init=/linuxrc
initrd /boot/initramfs-genkernel-x86_64-2.6.32-gentoo-r1
title=Gentoo Linux (2.6.31-gentoo-r1)
root (hd0,0)
kernel /boot/kernel-genkernel-x86_64-2.6.31-gentoo-r1 root=/dev/ram0 crypt_root=/dev/sda2 real_root=/dev/vg/slash dolvm init=/linuxrc
initrd /boot/initramfs-genkernel-x86_64-2.6.31-gentoo-r1 |
Its boots fine using 2.6.31 and fails using 2.6.32, as you can see on the following pictures:
https://politbuero.dyndns.org/2.6.31-works.jpg
https://politbuero.dyndns.org/2.6.32-fails.jpg
I have spent *many* hours recompiling the kernel and cursing at make menuconfig, trying to find the missing option. When I type "shell" after 2.6.32 has failed to find the vg, there indeed is no "/dev/vg/" as there is when the volume group "vg" is found. PLEASE, do you have an idea why its not finding the volume group after decrypting the LUKS device?
Sorry for the crappy pictures. And thanks for your help!

What is the output of pvdisplay, vgdisplay, and lvdisplay when booted into 2.6.32? I assume the output you gave was for 2.6.31, since everything was found and shown.
[Edit: fixed markup mistake.]

Hu, thank you for your answer!
I am currently not physically at the machine in question, but I can log into it. Yes, those outputs are from 2.6.31 running (not the rescue shell, but the real system). I tried using these commands in the 2.6.32 rescue-shell and I got "command not found", so I thought this was normal and the init scripts used other means of detecting LVs.
Now I just unpacked the initramfs's of both .31 and .32, and their bin/lvm files have the same md5sum. Found out that the init scripts just create e.g. vgscan symlinks to bin/lvm and then call e.g. "vgscan 2>/dev/null"
I'll see what the 2.6.32 vgscan says when its stderr is not redirected to /dev/null and then report back.
Thanks again, Hu, you made me discover the init scripts  |

I just got back from the machine and took more crappy photos...
https://politbuero.dyndns.org/problem/
There's really not much more to say than whats visible on the pictures... vgscan doesn't give any errors while finding nothing, dmesg has no errors either. There simply are no volume groups found. Even specifying --debug and --verbose didn't really help.
I was surpised to find no mention of the words LVM/lvm in dmesg, but its the same with the working 2.6.31 kernel, so I guess thats fine.
Does maybe https://politbuero.dyndns.org/problem/2.6.32-busybox-no-dev-vg-directory2.jpg give a clue to you?
I'm lost. Please advise! |
