[lfs-support] Help: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0, 0)

[Jimmy Zhang]

Hi,I followed the instruction on LFS-BOOK-8.3.pdf step by step to the end.During the reboot, I got the error message "Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)".I was building LFS with my VMware machine.Need help to see which part I may mess up?Thanks,Jimmy Zhang

Usually this is caused by missing device drivers in the kernel so that
the kernel isn't able to read the root file system. This can be caused
by missing filesystem drivers like ext4 or by missing drivers for the
disk devices itself like PATA or SATA.
Check the kernel configuration for that.

Jimmy,

Look for Fusion MPT support and build all of that, as well as the VMWare
VMCI Driver, SCSI Disk/Device/Generic support, Buslogic SCSI support,
and PVSCSI support. You might need the VMXNET3 driver as well.

since so many people seem to build in VMs, and have problems, maybe
we ought to document this somewhere ? Alternatively, perhaps using
lsmod like on a distro does actually work on VMs ?

I build using OverlayFs.  It is much better than to try to build it in a
VM. I make a container that will have the host build system:

    msg_line "Creating root filesystem container - this may take awhile
--> "
    dd if=/dev/zero of=host.img bs=4096 count=512000 > /dev/null 2>&1
    mkfs -t ext4 host.img > /dev/null 2>&1

then populate it with a host system ie PClinuxOS or LFS-8.2.

This gives me a host system called host.img

It gets mounted as read only:

OVERLAY=OVERLAY

msg_line "Mounting file systems --> "
mountpoint -q ${OVERLAY}/lower        || mount --read-only host.img
${OVERLAY}/lower
mountpoint -q ${OVERLAY}/overlay        || mount -t overlay overlay -o
lowerdir=${OVERLAY}/lower,upperdir=${OVERLAY}/upper,workdir=${OVERLAY}/workdir
${OVERLAY}/overlay
mountpoint -q ${OVERLAY}/overlay/dev    || mount --bind /dev
${OVERLAY}/overlay/dev
mountpoint -q ${OVERLAY}/overlay/dev/pts    || mount -t devpts devpts
${OVERLAY}/overlay/dev/pts -o gid=5,mode=620
mountpoint -q ${OVERLAY}/overlay/proc    || mount -t proc proc
${OVERLAY}/overlay/proc
mountpoint -q ${OVERLAY}/overlay/sys    || mount -t sysfs sysfs
${OVERLAY}/overlay/sys
mountpoint -q ${OVERLAY}/overlay/run    || mount -t tmpfs tmpfs
${OVERLAY}/overlay/run
msg_success

Then:

msg "Chrooting overlay file system --> "
chroot "${OVERLAY}/overlay" \
    env -i \
    HOME=/root \
    TERM="$TERM" \
    PS1='(blfs chroot) \u:\w\$ ' \
    PATH=/bin:/usr/bin:/sbin:/usr/sbin:/tools/bin \
    /bin/bash --login +h

I then build the new system.

The "lower" filesystem never gets changed

the "upper" contains all the newer files and changes to the lower ro
filesystem

the overlay is the merge filesystem (lower merged with upper) and it is
where you do your work

Hi,One thing I am confused that the LFS kernel (/boot/vmlinuz-4.18.5-lfs-8.3 from my partition(one partition for both /boot and /) was loaded and run, which indicated that the system can access my partition /dev/sda3 which was going to be mounted as root, right? why the kernel will give the error messages that unable to mount root fs?ThanksJimmy

Grub can access your partition and copy the kernel into your RAM. But then
the kernel can not access your partition because it doesn't have proper driver.

Jimmy,
Might also be that the FS is corrupted?
Boot from a live DVD, and
fsck -y /dev/sda3
andthe remove the live dvd
and boot normally.
Might work!!
If it does not work,
you will have to re-install the OS.

Now that is *very* strange advice to offer on LFS, rather like the
sort of "drive by" responses sometimes seen on forums by people who
don't understand how LFS is built.

In particular "re-install the OS" is an odd thing to say here. The
error message clearly implies that the kernel does not have a
required driver. For that, going back to chroot and fixing the
kernel config is the normal process.

1. If the kernel does not have the required driver,
how did LFS end up on the drive?
2. Just exactly what driver are you referring to?
"Driver" is a generic term which is used to to refer to different
interfaces in the kernel.
YOU claim that to say "re-install" is a strange piece of advice.
I, actually, everyone, would love to hear from you just exactly which
driver the OP is missing.

Hey Bruce,
you are saying that LFS varies and depends on the hardware??
Exactly which hardware?
The disk IO layer drivers are dependent on type of disk HW interface at
the lowest level.
Above that an abstraction layer is used, and it is possible (if
necessary) to build yet
another abstraction layer above that.
The FS's LFS layer is built on top of the "block io" layer, as the file
system works
with BLOCKS.
So, please explain what type of hardware is LFS dependent on?

So, maybe you are here to troll ?

On the off-chance that you are not trolling: linuxfromscratch (LFS)
is installed in a chroot by building from a pre-existing linux
system running on the same machine.

As part of that, some parts of the build may be specific to the
machine (or what a VM presents as, if building in a VM), e.g. gmp
goes out of its way to optimise for what is expected to be present
on that machine (see past issues where a low-end pentium of what was
then the latest intel family lacked an instruction which whoever had
updated gmp's configure script thought was present on all of that
family).

And the kernel configuration, because we expect the builder to build
for the machine he or she is using, will vary from one machine to
the next.

So, you are now claiming to be talking about the Large File System.
And yet you earlier said 'NO' to the suggestion that is what you
were talkign about.

We have no interest in that (strictly, we expect it to be installed
on the linux machine we use to build linuxfromscratch, and it will
be used in linuxfromscratch as in all other sane modern linuxes -
limiting files to 4GB on modern disks is not a good idea.

We expect people here to build a LINUX kernel (indeed, our methods
are clearly not going to work on FreeBSD), and as part of that you
get the choice, in 'make menuconfig', of which drivers to include.

I'll file your posts under 'troll'.

1. If the kernel does not have the required driver,
how did LFS end up on the drive?

As Bruce has already answered.

2. Just exactly what driver are you referring to?
"Driver" is a generic term which is used to to refer to different
interfaces in the kernel.
YOU claim that to say "re-install" is a strange piece of advice.
I, actually, everyone, would love to hear from you just exactly which
driver the OP is missing.

People have already made suggestions - I do not use vmware, but
there were suggestions about that.

From a normal distro system which has been used to build LFS, in
chroot 'lsmod' will show which modules are currently loaded. I
assume that a distro running on vmware will do the same.

So as a first step, all of those need to be available in the kernel.
For things like network devices, modules should be fine in LFS. But
for the disk drivers, and the filesystem used on the LFS partition,
they need to be built-in, not modules, because we do not use an
initrd.

Later, it is often possible to slim-down a kernel config by removing
items which seem unnecessary (but obviously, keep the existing
working kernel when trying to do that, and use a different version
for the experiments).

So, for the filesystem - ext4 (unless the builder used something
else).

For the disk drives - it depends very much on the motherboard and
(on some motherboards) which port is used for the disk. On the
machine where I'm writing this I have

CONFIG_ATA=y
CONFIG_ATA_VERBOSE_ERROR=y
CONFIG_ATA_ACPI=y

CONFIG_SATA_AHCI=y

On some other machines I have added, variously,

CONFIG_SATA_PMP=y
CONFIG_SATA_INIC162X=y
CONFIG_SATA_ACARD_AHCI=y
CONFIG_ATA_SFF=y
CONFIG_ATA_BMDMA=y
CONFIG_ATA_PIIX=y
CONFIG_PATA_AMD=y
CONFIG_PATA_ATIIXP=y

But for a virtual machine I assume that the disk driver is
determined by the VM not by the underlying hardware.

Hi,
I followed the instruction on LFS-BOOK-8.3.pdf step by step to the
end.
During the reboot, I got the error message "Kernel panic - not
syncing: VFS: Unable to mount root fs on unknown-block(0,0)".
I was building LFS with my VMware machine.
Need help to see which part I may mess up?
Thanks,
Jimmy Zhang

Usually this is caused by missing device drivers in the kernel so that
the kernel isn't able to read the root file system. This can be caused
by missing filesystem drivers like ext4 or by missing drivers for the
disk devices itself like PATA or SATA.
Check the kernel configuration for that.

Jimmy,

Look for Fusion MPT support and build all of that, as well as the VMWare
VMCI Driver, SCSI Disk/Device/Generic support, Buslogic SCSI support,
and PVSCSI support. You might need the VMXNET3 driver as well.


Hi guys,I added PATA, SATA, VMWaer VMCI Driver, SCSI drivers and my kernel continued and passed the panic spot I reported.But still stopped at 
Looks still missing some drivers. Any suggestions will be appreciated.Thanks for all your support.Jimmy

Ah, some progress made.

Maybe you zip the kernel config (.config) and post it here together
with the grub.cfg?
