I'm rather new to both Debian and OpenVZ and have been struggeling with a problem for which I can not find a solution. I can't imagine that nobody has ran into this problem before or maybe I'm just plain stupid, but thusfar I haven't been able to find some concrete information anywhere.

On a fresh installation of Debian, I installed OpenVZ following the wiki guidelines "Installation on Debian" (http://wiki.openvz.org/Installation_on_Debian). When I reboot my system, it halts with the foloowing message:

VFS: Cannot open root device "sda2" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(0,0)

Has anyone seen this problem before and found a solution for it? If so, I very much like to hear about it.

Regards,

Pieter-Jan de Vries

Hello,

Please, boot in the working kernel and post here the contents of /boot/grub/menu.lst (or /boot/grub/grub.conf). Also, please, post listing of /boot directory and output of `lspci` and `lspci -n` commands.

The problem is that no driver for your block device is in kernel. The reasons can be various, for example: no or bad initrd image, unsupported hardware, etc.

Vasily.

Hi vasily,

Thanks very much for your reply. I figured it had something to do with a missing driver of some sort, but I can not figure out which one and/or how to add that missing driver.

Actually I just started with a fresh Debian install in an attempt to build my own kernel, so the information you requested does not show the details of the OpenVZ kernel. If you need that as well, please let me know and I'll redo my previous installation to supply you with the missing pieces.

This is the information you asked for:

Strange, but according to information, you've provided, there is only one kernel installed Rolling Eyes
Have you removed previous attempts? Smile

Your hardware is quite usual. What config do you use while compiling the kernel? Is CONFIG_BLK_DEV_PIIX enabled?

Thanks,
Vasily.

Yes, at this moment I have only one kernel installed. Before I got your initial reply, I had already done a fresh Debian install and started to try to do a kernel rebuild myself.

The first time I did not compile the kernel myself. I followed the instructions on "Installation on Debian" wiki.openvz.org (see http://wiki.openvz.org/Installation_on_Debian). I assumed that an 'aptitude install' is always safe. The configuration file that comes along with that kernel has CONFIG_BLK_DEV_PIIX=y

Is that of any help?

Pieter-Jan de Vries

Hi pjdevries,

Have you download a precompiled "kernel-image" like
ovzkernel-2.6.9 from debian.sys.org ?

Problem(s) ... you booted a standard Debian Kernel Image ...

Thanks for the reply Thorsten.

You could say I downloaded a precompiled kernel-image because that is what "aptitude install ovzkernel-2.6.9" does, doesn't it? As I explained to Vasily, I followed the instructions "Installation on Debian" on wiki.openvz.org (see http://wiki.openvz.org/Installation_on_Debian). That makes it even more frustrating, because there is hardly anything one can do wrong.

Don't be fooled by the info I posted earlier. That info was obtained from my system with a fresh Debian install, so without the OpenVZ kernel installed. After I installed the above mentioned kernel, my /boot/grub/menu.lst looks like this:

title Debian GNU/Linux, kernel 2.6.9-023stab037.3-ovz
root (hd0,1)
kernel /boot/vmlinuz-2.6.9-023stab037.3-ovz root=/dev/sda2 ro
savedefault
boot

savedefault
boot

title Debian GNU/Linux, kernel 2.6.8-2-386
root (hd0,1)
kernel /boot/vmlinuz-2.6.8-2-386 root=/dev/sda2 ro
initrd /boot/initrd.img-2.6.8-2-386
savedefault
boot

title Debian GNU/Linux, kernel 2.6.8-2-386 (recovery mode)

kernel /boot/vmlinuz-2.6.8-2-386 root=/dev/sda2 ro single
initrd /boot/initrd.img-2.6.8-2-386
savedefault
boot

As you can see, I did not boot a standard Debian Kernel but a custom (precompield) OpenVZ kernel which I obtained from the Debian stable repository.

So, still no solution for my problem:( Any help is welcome and all efforts are enormously appreciated.

Pieter-Jan de Vries

Moin,

can you please paste the output of "dmesg" of you running OpenVZ kernel.

The problem is I don't have a running OpenVZ kernel because, as I explained in my initial message, it won't boot Sad

Hi Pieter-Jan,

sorry i mean to put your non-OpenVZ kernel dmesg,

but i put the old stable OpenVZ kernel with Version 2.6.8
(022stab078.21) to http://forzza.systs.org/old/kernel/

Please download it and boot with this 2.6.8er OpenVZ kernel.

Seems that your SATA Hardware has a prob with a 2.6.9er Kernel.

And afterwards can you post I've your mascine is booting and running the OpenVZ with Kernel 2.6.8.

Thanks
Thorsten

Unforntunately that kernel doesn't boot either (fails with the same message). But shouldn't I have an initrd for this kernel? My default 2.6.8 kernel has one too. And if so, can you give me some pointers how to create one? Although I ran into some examples in various places, I'm not quite sure which modules to include and how/where. The fact that modules and modules.conf appear both in /etc and in /etc/mkinitrd make matters rather confusing.

Anyway, here is the dmesg output from my Fresh Debian install:

I just remembered that I did have a working OpenVZ setup some time ago, when I just started out experimenting with OpenVZ on this machine. Best of all: I still have an image of that installation so I managed to have that configuration up and running again in a matter of minutes.

The difference between the working and the failing situation is that previously I installed Debian on a (software) RAID-1 configuration. Later I decided to to go for a two machine cluster using DRBD and Heartbeat and it seemed a bit over-redundant to use both DRBD and RAID-1.

So here is the "dmesg" output on a running OpenVZ kernel, although not exactly in the configuration I want:

2 pjdevries:

You can boot your debian kernel, and then compare debian kernel .config vs openvz .config

You can find config files here:
/boot/config-YOUR_KERNEL_VERSION

or maybe here:
/lib/modules/YOUR_KERNELS/build/.config

Pay attention to options around CONFIG_BLK_DEV, maybe it is good idea to reconfigure OpenVZ kernel, and set CONFIG_BLK_DEV_DRBD=y.

I prefer to edit .config by hands. You have similar kernel versions, so you can just paste and copy block device options from debian .config to openvz .config, then say:

$ make oldconfig

in openvz kernel directory, and answer to some questions about new openvz options. (just press enter if unsure).

Then build the kernel:

$ make
$ make modules_install
$ make install

Thanks for the reply. I have been staring at the configuration files quite a couple of times already. Unfortunately I'm completely new to this and 2837 lines in the default config file and 1598 lines in the OpenVZ config file don't make things any easier. I just don't have the foggiest idea which options to configure. but I'll give it another try.

Regards,

Pieter-Jan de Vries

A question related to comparing and synchronising the two config files:

How do I handle options that are configured as 'm' in one configuration file but configured as 'y' in the other? The default Debian installation has an initrd but the OpenVZ kernel doesn't. It also appears that the OpenVZ kernel has most options set to 'y'.

First of all, please make backup of original OVZ .config file Smile

Kernel configuration can be done not only by 'hands', you can use:

$ make menuconfig
or
$ make xconfig
or
$ make config

in this case you will be able to see help messages for each option, try to undestand what do you realy want in block device section.

BTW, I'm not sure that it will work, but you can just do the followings:

$ cp Debian_Kernel_src/.config OVZ_Kernel_src/.config
$ cd OVZ_Kernel_src/
$ make oldconfig
(press 'enter' everywhere)
$ make
$ make modules_install
$ make install

If everything will be ok with compilation (I'm not sure Smile), you can reboot and ensure that this OVZ kernel can mount your root filesystem.

AFAIK each 'nonembedded' kernel must have initrd enabled - it contains modules for your kernel.

The 'initrd /boot/initrd_for_your_OVZ' line must be present in bootloader configuration file for each kernel, but it is missed for OVZ kernels in your menu.lst!!!

Generally, "make install" add initrd line to bootloader config, but if the mkinitrd package is not installed in your Debian, or something else is broken, this line will not be added, but you can add this line by hands.

If /boot/initrd_for_your_OVZ file is also missed, please check that the 'mkinitrd' package is installed in your OS and the mkinitrd command works ok.

At last I have a working OpenVZ kernel om my machine. Ultimately it was a matter of configuring the right devices as modules in the kernel configuration file and creating an initrd. In my case the device options to configure as modules are: CONFIG_BLK_DEV_SD, CONFIG_BLK_DEV_SR, CONFIG_SCSI_ATA_PIIX, CONFIG_BLK_DEV_PIIX and CONFIG_MOUSE_PS2. The latter not specifically to get the kernel to boot but to get rid of annoying error messages. I'm not sure if all of these are actually required, but it works.

Many thanks to Thorsten and Alexandr for their interest and support. Especially to Alexandr who gave me a few pointer that got me on the right track.

Regards,

Pieter-Jan de Vries

Hi Pieter-Jan,

perfect, but one question Smile

I wonder why the stable ovzkernel (2.6.9) doesn't start,
the needed modules :

CONFIG_BLK_DEV_SD=y
CONFIG_SCSI_ATA_PIIX=y
CONFIG_MOUSE_PS2=y

are build-in, (so the kernel shoulded boot without a initrd)

CONFIG_BLK_DEV_SR=m (SCSI CDROM)
is build as loadable module in the ovzkernel-config.

Can you please poste what kind of modules have you enabled to start your ovzkernel.

My thoughts exactly. In fact this has wrong-footed me right from the start and prevented me from exploring the option of making an initrd until the end. I have to admit that I'm still on unfamiliar territory and just making educated guesses. But the fact remains that my kernel boots after having changed those parameters from built in to loadable.

If by 'what kind of modules have you enabled to start your ovzkernel' you mean the contents of my /etc/modules, then this is it:

psmouse
sd_mod
sr_mod


Yo can see why I configured CONFIG_BLK_DEV_SD, ONFIG_MOUSE_PS2 and CONFIG_BLK_DEV_SR as loadable modules, although you are right with CONFIG_BLK_DEV_SR being configured as loadable by default. I can not remember why I also decided to configure CONFIG_SCSI_ATA_PIIX as loadable. It was more or less a guts feeling based on all kinds of information and error messages I saw during my various experiments. To be honest I'm not even sure if either of those options can be left configured as bulit in, because once it worked I didn't bother any more Embarassed

If there is any additional information I can give to clear things up, just ask for it. I would prefer to have a better understanding of how things should work as well. After all: I still don't know exactly how to configure and build a kernel in the proper way. I got it to work by try and error and more or less educated guessing.

Do you konw of any good, detailed, monkey proof documentation or tutorial about building kernels, with or without initrd, that not only outlines the steps to be taken but also why they should be taken? It might enable me to solve the next problem I face: the loadable DRBD module in my working OpenVZ kernel. The problem is that the version of that module is 0.7.20 (api:79/proto:74) while the supported version of the drbd0.7-utils (and drbd0.7-module-source) available from the stable debian repository is 0.7.10 (api:77) and they don't work together. So either I get hold of a drbd0.7-utils version 0.7.20, which doesn't seem to be available as a debian package, or I compile my current OpenVZ kernel with the available 0.7.10 module sources, which I don't know how to do.

Have a nice turn of the year!

Pieter-Jan de Vries

Thanks once again Thorsten. I will definitly dive into that.

I sort of have the idea that you know quite a bit about OpenVZ. If you can spare the time, would you be so kind to take a look at another issue I have posted about a week ago (http://forum.openvz.org/index.php?t=msg&goto=9583&)?

Pieter-Jan de Vries
