Posted: Sun Oct 18, 2020 1:42 pm Post subject: grub not seeing new kernel [SOLVED] |
|
|
Dear All,
I am running gentoo stable on an FX 8350 machine.
I compiled a new kernel (5.9.0) and installed it in the /boot directory.
I tried running grub-mkconfig to attach it to the grub table on booting the machine.
But it doesn't work.
Code: | ➜ mikef ping www.google.com
ping: connect: Network is unreachable
➜ mikef grub-mkconfig -o /boot/grub/grub.cfg
Generating grub configuration file ...

The problem with could be a bug possibly according to other posts I have looked at.
My directory looks like this:
Code: | ➜ mikef cd /boot
➜ /boot ls -la

Suggestions on fixing this would be greatly appreciated.

Many thanks for your advice.
I ran the two commands you suggested.
After rebooting when I ran the command again I did not get the warning messages.
That has improved things for me.
But the new kernels were still not attached to the grub table on boot up.
Cheers
MF
PS I tried reinstalling grub:
Code: | ➜ mikef grub-install /dev/sda
Installing for x86_64-efi platform.
grub-install: error: cannot find EFI directory.
➜ mikef |
Something is not right there.... |

In your "grub-install" line.
You are using a bios invocation when in fact it should have been an uefi
Code: |
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=gentoo --recheck.
|
I am also a bit confused.
You seem to have lvm.
Can you please run
Code: |
lsblk
cat /etc/fstab
|
and post the output.
The prefered structure --for me-- is separate /boot and /boot/efi directories.
If you use lvm then you will need a standard partition mounted on /boot.
If not you do NOT need separate /boot.Only an EFI partition mounted on /boot/efi.
Please run
Code: |
mkdir /boot/efi
#####Then create a 500M partition with gdisk and mark it ef00 Then run
mkfs.vfat </dev/partition-name>
mount /dev/<partition-name> /boot/efi
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=gentoo --recheck
|
followed by
Code: |
dracut /boot/initramfs-$(uname -r).img $(uname -r) ####To create new OR
dracut --force ### to update existing ----if you have dracut.I dont know how you do it with genkernel.
grub-mkconfig -o /boot/grub/grub.cfg
|
Do you use lvm??? _________________

Many thanks for your advice.
The output of lsblk is here:
Code: | (chroot) pigface / # lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 232.9G 0 disk
├─sda1 8:1 0 8.3G 0 part
├─sda2 8:2 0 86.4G 0 part
├─sda3 8:3 0 4.9G 0 part
└─sda4 8:4 0 133.3G 0 part / |
and
Code: | (chroot) pigface / # cat /etc/fstab
# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed); notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# See the manpage fstab(5) for more information.
#
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
#
# NOTE: Even though we list ext4 as the type here, it will work with ext2/ext3
# filesystems. This just tells the kernel to use the ext4 driver.
#
# NOTE: You can use full paths to devices like /dev/sda3, but it is often
# more reliable to use filesystem labels or UUIDs. See your filesystem
# documentation for details on setting a label. To obtain the UUID, use
# the blkid(8) command.
/dev/sda1 /boot/efi vfat noauto,noaatime 1 2
/dev/sda4 / ext4 noatime 0 1
/dev/sda3 none swap sw 0 0
#/dev/cdrom /mnt/cdrom auto noauto,ro 0 0
(chroot) pigface / # |
I am now running gentoo from an ubuntu install on the same drive.
I mounted the root partition and chrooted into gentoo from ubuntu.
I can mount the boot partition for gentoo as well if needed.
Cheers
MF
PS
Opening a second terminal as in ubuntu and running shows that is the partition:
Code: | ➜ mikef lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 232.9G 0 disk
├─sda1 8:1 0 8.3G 0 part /boot/efi
├─sda2 8:2 0 86.4G 0 part /
├─sda3 8:3 0 4.9G 0 part
└─sda4 8:4 0 133.3G 0 part /mnt/gentoo
➜ mikef mount /sda1 /boot/efi
mount: /boot/efi: special device /sda1 does not exist.
➜ mikef |
But when you try to mount the partition it doesn't work:
Code: | ➜ mikef mount /sda1 /boot/efi
mount: /boot/efi: special device /sda1 does not exist.
➜ mikef
|
Something is not right there.
PPS
I already have an directory:
Code: | (chroot) pigface /boot/efi # ls -l
total 0
|
PPPS I don't have turned on anywhere in my file if that would be possible that I can see and I don't have any related use flag present in the file either.
Maybe if I would create the extra 500MB partition and label it as you say and run the command you gave that will solve the problem.....
Comments appreciated.
PPPPS
Ubuntu is on /sda2; the common swap partition is on /sda3 and the root partition for gentoo is on /sda4 |

Ok from what I see first you do not seem to have logical volumes therefore lvm is unnecessary.
Secondly you do not seem to have a /boot/efi partition.
According to your fstab
/dev/sda1 IS the ESP partition but from lsblk i see it is a 8.3 Gigs partition.
Something doesnt feel right.
Since you do not have lv's you dont need to have a separate /boot partiion.
Just the "/" and /boot/efi
But you MUST have a /boot and /boot/efi directories in your fs.
Just create the ESP partition and MOUNT it on /boot/efi NOT on /boot.
Please do something like that:
First edit your fstab with the name of your new EFI partition.
Then please run:
Code: |
####FROM UBUNTU
mount /dev/sda4 /mnt
mount /dev/<your new EFI partition you should create> /mnt/boot/efi
mount --rbind /dev /mnt/dev
mount --make-rslave /mnt/dev
mount -t proc /proc /mnt/proc
mount --rbind /sys /mnt/sys
mount --make-rslave /mnt/sys
mount --rbind /tmp /tmp
chroot /mnt /bin/bash
source /etc/profile
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=gentoo --recheck
|
I dont know what is your initramfs setup.If you use one create it or update it.
Then update grub:
Code: | grub-mkconfig -o /boot/grub/grub.cfg |
Then exit the chroot and reboot.
You mention
Quote: |
➜ mikef mount /sda1 /boot/efi
mount: /boot/efi: special device /sda1 does not exist.
➜ mikef
|
It should have been
mount /dev/sda1 /boot/efi
BUT /dev/sda1 does NOT seem to be an EFI partition.IT is 8.3Gigs!!!
What does /dev/sda1 contain? _________________

Is your kernel configured for dos/vfat filesystems? _________________ PRIME x570-pro, 3700x, 6.1 zen kernel

Many thanks for your advice.
I checked the kernel I was using. The and flags are turned on.
Do I need the stuff turned on as well?
I tried turning that on as well and recompiling the kernel.
I got the
Code: | no rule to make target 'arch/x86/tools/relocs_32.c' |
type error when I tried running after exiting from .
Comments appreciated.

I tried running genkernel all to make a kernel it failed saying there was no boot mount point.....
I ran emerge sys-kernel/vanilla-kernel and made a new kernel.
I will try getting grub to see it.

It looks like it might have worked.
I will try rebooting to see if the new 5.9.1 kernel is there and whether I can actually log in with it.
PPPS
I managed to boot up this kernel and log in with it with the help of supergrub. |
