|

Hello,
This topic is out-dated, an installation with LVM seems to brings too many problems as it is for now. I re-installed the system, and I have still problem to boot it up, more here.
Thanks for your time and help, will try to close this topic.
this is the context:
I use SystemD Stage and follow the AMD64 Handbook.
From Debian 12 I resized my hard drive and set up a volume group (LVM) of 250Gb to host a Gentoo fresh installation. Both hard drive containing OS are using GPT tables. Alongside them there is also a Windows 11. I used a chroot to install Gentoo from Debian.
In that volume group I have:
/ : 64Gb, ext4
/home: 128Gb, ext4
/usr/src: 10Gb, ext4
/var/cache/distfiles: 30Gb, ext4
/var/tmp/portage: tmpfs
In fstab these partition are mounted like this:
Code: | ### LVM
### https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/System#Filesystem_information
### "UUIDs of the filesystem on a LVM volume and its LVM snapshots are identical, therefore"
### "using UUIDs to mount LVM volumes should be avoided."

# "The size parameter can be adjusted in /etc/fstab to set the max size of the tmpfs,"

# "significantly."
#
# From @sam on #gentoo@libera.eu.chat: having only 8Gb left for system is a terrible idea.
# 16Gb is probably more suited with 32Gb of memory.

EDIT: While composing this message, I just realized that Debian is mounting the /boot/efi partition at boot, while Gentoo was not. So I added this line:
Code: | UUID=569B-9899 /boot/efi vfat umask=0077 0 1 |
[i](Same, exact problem, but at least I think I needed it…)[/i]
After some days of questionning and trying, I got a newly installed Gentoo… that is unbootable in that state. GRUB (from Debian) don't detect it if using os-prober, updating grub and re-installing it on my main drive (where are Debian and Windows main partition, / and C:, as the ESP partition).
If I try to boot directly on that hard drive (with Gentoo LVM VG), I get a GRUB error:
Code: | GRUB Loading.
Welcome to GRUB!
error: file '/boot/grub/i386-pc/normal.mod' not found.
grub rescue> _ |
The thing is while installing Gentoo's bootloader, midway I realized I should keep GRUB from Debian «just in case» and just add Gentoo. I removed since sys-boot/grub, removed the GRUB_PLATFORMS line.
And now I'm stuck.
Other things I noted on my Gentoo's chroot that /boot is very different from Debian:
On Gentoo:
Code: | Desktop / # ls /boot/*
/boot/config-6.1.53-gentoo-dist /boot/System.map-6.1.53-gentoo-dist /boot/vmlinuz-6.1.53-gentoo-dist
/boot/initramfs-6.1.53-gentoo-dist.img /boot/System.map-6.1.53-gentoo-x86_64.old /boot/vmlinuz-6.1.53-gentoo-x86_64.old
/boot/grub: |
On Debian:
Code: | [08:26:01]
[Kernel: 6.1.0-12-amd64 - Debian: 12.1]
[root]@[Desktop] [~]
# ls /boot/*
/boot/config-6.1.0-12-amd64 /boot/initrd.img-6.1.0-12-amd64 /boot/System.map-6.1.0-12-amd64 /boot/vmlinuz-6.1.0-12-amd64
/boot/efi:
EFI
/boot/grub:
fonts grub.cfg grubenv locale unicode.pf2 x86_64-efi
/boot/lost+found: |
The ESP partition is on the same hard drive as Debian and Windows, but not Gentoo. This partition contains as you can see here:
Code: | [08:28:53]
[Kernel: 6.1.0-12-amd64 - Debian: 12.1]
[root]@[Desktop] [~]
# ls /boot/efi/EFI/
Boot debian Microsoft |
I think, and I could be very wrong, that Gentoo don't «know» where is the ESP partition.
Since I'm not sure what is relevant, a few files and command output that seems always important:
Code: | Desktop / # cat /etc/portage/make.conf

Kind of lost here. Have you an idea to wake up Gentoo ?

Hello kgdrenefort,
I could be wrong, but from inspecting your setup, it seems that Debian installed the bootloader to the ESP created by Windows, but in your actual Debian install, the /boot and /boot/efi appear to be within the context of your / partition.
If you run df after boot, see if your ESP partition is showing up in the list. This is an easy way to see if it had been loaded by the OS.
Potentially, you need to make sure to unmount the ESP after booting into both Debian and Gentoo separately, where you can then find if there are files within /boot or /boot/efi which are actually on the / partition, then remove the contents of those directories if this is the case. Then you would mount the real ESP (which contains the folders 'debian' and 'Microsoft') and re-run the grub-install. Hopefully, after doing this on both Linux installs, you have a Grub menu for Gentoo, Debian and Windows.
If you use systemd, I would recommend systemd-boot over grub, there is much less that can go wrong - if you are on OpenRC this is obviously not an option. I feel that maybe systemd-boot adoption is sparse in the Gentoo community so if a guide would be helpful, I could write one.
edit:
I've seen that you have two boot partitions
Code: | /dev/sda2 1085440 1290239 204800 100M EFI System
/dev/sda7 281970688 283924479 1953792 954M BIOS boot |
Likely /dev/sda7 "BIOS boot" is not needed. I don't see it in your fstab? I'm not sure that it's doing anything. |

I can't remember honnestly, so far:
- I installed Windows 11 by replacing 10
- I had to re-install this Debian 12 after some time for no related reasons
So it's possible that this ESP partition come from Windows, I have to many old habbits from BIOS I didn't completly get rid off I guess.

The partition is mounted at boot time, as asked by fstab on Debian:
Code: | /dev/sdb2 96M 35M 62M 37% /boot/efi |
Code: | # /boot was on /dev/sdb11 during installation
UUID=30d970a9-3a7b-448d-922b-4ed2ddfec145 /boot ext2 defaults 0 2
# /boot/efi was on /dev/sdb2 during installation
UUID=569B-9899 /boot/efi vfat umask=0077 0 1 |
As we can see, during /boot and /boot/efi (ESP partition) where pointed, I did not modified anything after that for these.

I don't get this: I should unmount on Debian and Gentoo the ESP (aka /boot/efi on Debian) after each boot ? What is the purposes ?
Do you mean that the /boot partition into Debian is plain wrong and should probably removes it ?

Could be a good idea, but for now I would really like to keep this on GRUB from Debian.

You mean is not needed because there is the EFI System partition ?
I'll definitly read more about ESP partition, I'm outdated on that and it brings problem.
Beside, thanks for your reply, if you can explains a little bit more where I asked question, would help me understand where I'm wrong.

pc_user4,
The bios_boot partition is used by grub when BIOS booting and GPT are in use.
That's a combination that is not supported everywhere. That's the only time its required.
A 2M bios_boot is adequate, if its needed at all. Grub uses it raw. It does not have a filesystem and it does not belong to the user.
With BIOS booting, the first stage of the boot loader is the the MBR, in LBA 0. The next part follows, in the free space before the first partition when BIOS is in use.
When GPT is in use, the GPT starts at LBA 1, so that space is not available. Grub uses the bios_boot partition instead.
With EFI booting, the firmware loads an EFI compliant program from the ESP. There is no part of the boot loader outside of any filesystem. _________________ Regards,

Please make sure you have installed the package "lvm2" on Debian.
Then mount the partition which contains the /boot directory of Gentoo and rerun "sudo update-grub" and also "sudo os-prober". Share the input and output of the executed commands.
EDIT: And please show also from Debian:
Code: | echo "$(LVM_SUPPRESS_FD_WARNINGS=1 lvs --noheadings --separator : -o vg_name,lv_name | sed "s|-|--|g;s|^[[:space:]]*\(.*\):\(.*\)$|/dev/mapper/\1-\2|")"
