[SOLVED] LFS Version 9.1, 8.4.3. Setting Up the GRUB Configuration

spiky0011 · 07-10-2020, 03:59 PM

ok lets try grub.cfg again

set root=(hd1,2)

linux /boot/vmlinuz-5.5.3-lfs-9.1 root=/dev/sdb2 rootdelay=10 ro

How do i umount it

That is normal you won't umount those with that command, I'm more interested in the output of ls /boot and ls /boot/mnt after each of the commands in post 38

I don't think you have all the drivers needed to access your usb drive built into the kernel from you last sreenshot:

Quote:

Activating all swap files/partitions... swapon: cannot find device for UUID=617d3a82-8c40-4295-a41e-288251c1dfea

There is also similar message for your rootfs

mount: /: cant find UUID=42e174ea-46f1-4300-b5c5-870e7f9152f4

Good Morning,
Sir,
From Chapter 8.3.2. Configuring Linux Module Load Order

Quote:

The program
that loads modules, modprobe or insmod, uses /etc/modprobe.d/usb.conf for this purpose. This file needs
to be created so that if the USB drivers (ehci_hcd, ohci_hcd and uhci_hcd) have been built as modules, they will be
loaded in the correct order; ehci_hcd needs to be loaded prior to ohci_hcd and uhci_hcd in order to avoid a warning
being output at boot time.

Create a new file /etc/modprobe.d/usb.conf by running the following:

Quote:

install -v -m755 -d /etc/modprobe.d
cat > /etc/modprobe.d/usb.conf << "EOF"
# Begin /etc/modprobe.d/usb.conf
install ohci_hcd /sbin/modprobe ehci_hcd ; /sbin/modprobe -i ohci_hcd ; true
install uhci_hcd /sbin/modprobe ehci_hcd ; /sbin/modprobe -i uhci_hcd ; true
# End /etc/modprobe.d/usb.conf
EOF

What is this about?
Does this mean my drivers are loaded?
How do i check that?

Sir,
i also added
set root=(hd1,2)

and

linux /boot/vmlinuz-5.5.3-lfs-9.1 root=/dev/sdb2 rootdelay=10 ro

Sir,
i also added
set root=(hd1,2)

and

linux /boot/vmlinuz-5.5.3-lfs-9.1 root=/dev/sdb2 rootdelay=10 ro

ok I dont know why it's not finding the kernel.
Lets try using vmlinz from host boot
It looks like host is on sda4?

Shah404 · 07-11-2020, 03:46 AM

Sir,
yeah root system of host is on sda4.

You are saying i should change my grub.cfg to

Quote:

set root=(hd0,?)

linux /boot/vmlinuz-5.5.3-lfs-9.1 root=/dev/sda4 rootdelay=10 ro

what about

Quote:

set root=(hd0,?)

hd0 is first partition right, which is sda.
and what about other parameter?
what is that?

set root=(hd0,4)

linux /boot/vmlinuz-5.5.3-lfs-9.1 root=/dev/sdb2 rootdelay=10 ro

Just check that vmlinuz-5.5.3-lfs-9.1 Is in host /boot. from what I remember it was.

sda4 is ext4.
but insmod is ext2 in grub.cfg, is it wrong?, or i am wrong?

spiky0011 · 07-11-2020, 04:25 AM

paste whole grub.cfg to https://bpaste.net
paste URL back here

paste

Code:

lsblk

here

and vmlinuz-5.5.3-lfs-9.1 Is in host /boot.

The last time you compiled the lfs kernel,
what mount commands did your run to mount the lfs system and chroot into it,
commands you ran when compiled your lfs kernel?

Shah404 · 07-11-2020, 04:54 AM

Quote:

export LFS=/mnt/lfs

sudo mount -v -t ext4 /dev/sdb2 $LFS
sudo mount -v -t ext2 /dev/sdb1 $LFS/boot

sudo /sbin/swapon -v /dev/sdb3

su - lfs

sudo -s

export LFS=/mnt/lfs
cd $LFS

chroot $LFS /usr/bin/env -i HOME=/root TERM=$TERM PS1='(lfs chroot) \u:\w\$ ' PATH=/bin:/usr/bin:/sbin:/usr/sbin /bin/bash --login

then i untar linux-5.5.3.tar.xz
cd linux-5.5.3
make mrproper
make defconfig
make menuconfig
make
make modules_install

As a root user in host

Quote:

mount --bind /boot /mnt/lfs/boot

Then in lfs

Quote:

cp -iv arch/x86/boot/bzImage /boot/vmlinuz-5.5.3-lfs-9.1
cp -iv System.map /boot/System.map-5.5.3
cp -iv .config /boot/config-5.5.
install -d /usr/share/doc/linux-5.5.3
cp -r Documentation/* /usr/share/doc/linux-5.5.

Then usb.conf

Quote:

install -v -m755 -d /etc/modprobe.d
cat > /etc/modprobe.d/usb.conf << "EOF"
# Begin /etc/modprobe.d/usb.conf
install ohci_hcd /sbin/modprobe ehci_hcd ; /sbin/modprobe -i ohci_hcd ; true
install uhci_hcd /sbin/modprobe ehci_hcd ; /sbin/modprobe -i uhci_hcd ; true
# End /etc/modprobe.d/usb.conf
EOF

END

While make menuconfig
i couldnt find these
