[SOLVED] Problem adding completed LFS 11.3 partition to existing GRUB

peristaltic · 03-12-2023, 12:06 PM

Hello --

I completed the LFS 11.3 book (systemd version) last night. I did not follow the book's directions for compiling/installing GRUB since I planned to modify the existing GRUB entries on my host computer.

The LFS 11.3 partition is on /dev/sda2. The Linux Mint 21.1 host I used to build LFS is located on /dev/sdb3. Grub is installed on the MBR of sdb, set up in the BIOS as the first drive to boot.

After I completed the book, I ran the "grub-customizer" program on my host to add an entry for LFS. To my pleasant surprise, the program added an entry automatically: "unknown Linux distribution (on /dev/sda2)". I restarted, selected this new entry from the grub menu and LFS booted just fine.

However...

I noticed my networking on the LFS system was broken so I rebooted back into the host system to research how to fix it. When I tried to boot back into LFS a second time, I got a GRUB error:

Code:

error: no such device: 440f8ee8-6803-40dc-beca-4abae454dbfe.
error: file '/boot/vmlinuz-6.1.14-lfs-11.3-systemd' not found.
Press any key to continue...

I made no changes so I'm not sure what happened. I double checked the UUID for /dev/sda2 and it is correct.

I am perplexed why the LFS entry booted once but never again. I'm not sure where to start troubleshooting for fear of making things worse/corrupting my host system. Any help would be appreciated. Thanks.

At the grub menu, highlight the lfs entry, press e for edit, delete all this:

Code:

if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt2 --hint-efi=hd0,gpt2 --hint-baremetal=ahci0,gpt2  440f8ee8-6803-40dc-beca-4abae454dbfe
	else
	  search --no-floppy --fs-uuid --set=root 440f8ee8-6803-40dc-beca-4abae454dbfe
	fi

press ctrl-x to boot.
if it boots without no problem, change to this and see what happens:

Code:

if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root 440f8ee8-6803-40dc-beca-4abae454dbfe

At the grub menu, press e for edit and change all this:

Code:

if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt2 --hint-efi=hd0,gpt2 --hint-baremetal=ahci0,gpt2  440f8ee8-6803-40dc-beca-4abae454dbfe
	else
	  search --no-floppy --fs-uuid --set=root 440f8ee8-6803-40dc-beca-4abae454dbfe
	fi

to

Code:

search --no-floppy --fs-uuid --set=root 440f8ee8-6803-40dc-beca-4abae454dbfe

If that doesn't work boot into mint, open a terminal

Code:

sudo tune2fs -O ^metadata_csum_seed /dev/sda2

reboot and try again.

It didn't work the first time so I ran the tune2fs command.
It didn't work after that either.

Code:

Booting a command list

error: no such device: 440f8ee8-6803-40dc-beca-4abae454dbfe. 
error: file/boot/vmlinuz-6.1.14-lfs-11.3-systemd' not found.

Press any key to continue...

I appreciate your help. I'm starting to get discouraged.

what happens if you rerun sudo update-grub?

colorpurple21859 · 03-12-2023, 08:27 PM

the only other thing I can think of is umount the lfs partition and run a fsck on it.

You may be on to something here. Here is the output from fsck of /dev/sda:

Code:

fsck from util-linux 2.37.2
e2fsck 1.46.5 (30-Dec-2021)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sda

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem.  If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>
 or
    e2fsck -b 32768 <device>

Found a gpt partition table in /dev/sda

Nvm I forgot I needed to specify the partition not the device (sda2 not sda):

Code:

fsck from util-linux 2.37.2
e2fsck 1.46.5 (30-Dec-2021)
lfs: clean, 158169/2564096 files, 1615678/10255872 blocks

What is output of

Code:

sudo grub-probe --target=bios_hints --device /dev/sda2

then run again with —target=efi_hints

colorpurple21859 · 03-13-2023, 06:14 AM

Is fastboot enabled in the bios/firmware?

peristaltic · 03-13-2023, 09:22 PM

sudo grub-probe --target=bios_hints --device /dev/sda2

Code:

hd0,gpt2

sudo grub-probe --target=efi_hints --device /dev/sda2

Code:

hd0,gpt2
