I have an encrypted root partition on /dev/sda4. I am not using a lvm. Can anyone tell me want might be of with my configs?

# with the internal settings being least important, configuration file
# settings next, and command line options being most important.

# =========Common Command Line Option Defaults=========

# Should we install to $BOOTDIR?  Default is "no" because genkernel is used in
# catalyst and stage building.
#INSTALL="yes"

# Run 'make oldconfig' before compiling this kernel?
OLDCONFIG="yes"

# Run 'make menuconfig' before compiling this kernel?
MENUCONFIG="no"

# Run 'make clean' before compilation?
# If set to NO, implies MRPROPER WILL NOT be run
# Also, if clean is NO, it won't copy over any configuration
# file, it will use what's there.
CLEAN="yes"

# Run 'make mrproper' before configuration/compilation?
MRPROPER="yes"

# Override the arch detection?

# Use Color output in Genkernel?

# Clear build cache dir
#CLEAR_CACHE_DIR="yes"

# Clear all tmp files and caches after genkernel has run

# Genkernel uses an independent configuration for MAKEOPTS, and does not source
# /etc/make.conf . You can override the default setting by uncommenting and
# tweaking the following line. Default setting is set up by
# ${GK_SHARE}/${ARCH_OVERRIDE}/config.sh . The recommended value for -j
# argument is: <number of processors>*<number of cores per processor>+1

# Add new kernel to grub?
BOOTLOADER="grub"

# Enable splashutils in early space (initrd). Default is "no".
#SPLASH="yes"

# Use this splash theme. If commented out - the "default" name theme is used.
# Also, SPLASH="yes" needs to be enabled for this one to one work.

You defined GRUB_CMDLINE_LINUX twice. I think you should have written it only once.

This is what I use for my system with btrfs, systemd and genkernel-next:
Code:
GRUB_CMDLINE_LINUX="crypt_root=UUID=38641600-9879-4886-a1c4-5c30829c96ec root=/dev/mapper/root keymap=it rootflags=subvol=@ quiet init=/lib/systemd/systemd"


  • 38641600-9879-4886-a1c4-5c30829c96ec is the UUID of /dev/sda4, which is a LUKS partition.
  • You don't need rootflags=subvol=@ when not using btrfs subvolumes.
  • You don't need keymap=it if you use the default American keyboard layout

Hi nottobay,
Please tell us how the early boot log looks like? Are you dumped to kernel shell?
Can you manually unlock luks partiton via "cryptsetup luksOpen" command?

If I understand this correctly you aren't dropped to kernel shell, and system just remain "hanged" on that screen?

Please, could you post here the output of "cat /etc/crypttab", "cat /etc/fstab", "blkid" and "ls /boot" commands?

Since you are not using LVM I suppose that you commented out the "root=/dev/mapper/root" in your grub file as fturco suggested.
IMHO there should be only something like "crypt_root=UUID="your crypt partition UUID" root=UUID="your root partition UUID"" in GRUB_CMDLINE_LINUX if its luks without LVM.

I had to enable LVM support in genkernel-next even if I don't use LVM. See this for details. I'm aware it's not the same exact problem @nottobay is having, but it may help anyway...

Thanks for posting this.
Your "/etc/crypttab" should look like this:

Code:
var   UUID=your-var-/dev/sdaX-UUID   /keys/var-key     luks
swap   UUID=your-swap-/dev/sdaX-UUID   /keys/swap-key    luks
, and also you should put the root partition there too:
Code:
root UUID=6d9ad6eb-0f2e-448a-97c7-fe9dd29c28f6  none    luks
if it is enabled by passphrase.

GRUB_CMDLINE_LINUX should look like this:
Code:
GRUB_CMDLINE_LINUX="crypt_root=UUID=6d9ad6eb-0f2e-448a-97c7-fe9dd29c28f6 root=UUID=de9abd99-5b27-45f9-abbd-1255d4e04e58"


After changes in "/etc/crypttab" you have to recreate initrd, maybe enabling in genkernel.conf LVM could be helpful as fturco wrote.

Update your grub and please try to reboot the PC.

Well with OpenRC you don't need /etc/crypttab. That part goes in /etc/conf.d/dmcrypt instead. Crypttab is for systemd what I know about that.
OpenRC has a service dmcrypt that needs to go in to the boot runlevel and unlocks the other stuff for you during boot.

The kernel-bootparameters belongs to /etc/default/grub. I don't know if that part works in genkernel.cfg also. But I use genkernel only for building my initramfs.

Thats my /etc/default/grub:
Code:

GRUB_GFXPAYLOAD_LINUX=1280x1024
GRUB_DISTRIBUTOR="Gentoo"
GRUB_TIMEOUT=8
GRUB_ENABLE_CRYPTODISK=1
GRUB_CMDLINE_LINUX_RECOVERY='crypt_root=UUID=d5a3428b-b21c-42b4-a4ce-0818c92bca9c real_root=/dev/mapper/GENTOO-ROOT root_keydev=UUID=E716-DA12 root_key=dmcrypt-2.key single'
GRUB_TERMINAL_OUTPUT=gfxterm
GRUB_DEFAULT=saved
GRUB_GFXMODE=1280x1024
GRUB_SAVEDEFAULT=true
GRUB_CMDLINE_LINUX_DEFAULT='crypt_root=UUID=d5a3428b-b21c-42b4-a4ce-0818c92bca9c real_root=/dev/mapper/GENTOO-ROOT root_keydev=UUID=E716-DA12 root_key=dmcrypt-2.key splash'
GRUB_TIMEOUT_STYLE=menu
GRUB_THEME=/boot/grub/themes/starfield/theme.txt
GRUB_CMDLINE_LINUX="dobtrfs dolvm"


Use it as template. Maybe it helps. :)
The UUIDs are not mandatory but better. The root_keydev and root_key parameters are for unlocking via a keyfile. I use an usb-stick for that. If you prefer the password unlocking you need to integrate a suitable keyboard-driver to type your password without problems.

You build the kernel with genkernel? Do you use the option "--luks". Its mandatory for the initramfs. I also would use "--lvm" even if you don't use it. But luks depends on it. The keyboard-driver goes into the initramfs. You need it early if you have to password-unlock the crypt-disk. For that I would use "--do-keymap-auto" but not sure with that parameter.

I'm using a crypted root filesystem and lvm. And that with OpenRC.


Edit-1:
Just to make sure. You emerged sys-boot/grub with the useflag "device-mapper"?

Edit-2:
You builld the kernel-stuff and install it at /boot. Then you need an initramfs that supports the luks-stuff. I build it like this - just as template
Code:

genkernel --luks --lvm initramfs


If you build your kernel with genkernel completly, can you please post the output here? Just want to see if luks and lvm are really integrated for the initramfs,

Then you need to update grub.cfg. With my /etc/default/grub I can just use
Code:

grub-mkconfig -o /boot/grub/grub.cfg

for that.

Grub will output some lines for each kernel it finds.
If you get no errors you can reboot and hope it works. :)

Edit-3:
Ups - I missed the dmcrypt part sorry. Just look in the wiki here: https://wiki.gentoo.org/wiki/Dm-crypt
You find an example. Its at the end. And don't forget to add dmcrypt to the 'boot'-runlevel.

My gentoo system at boot. https://imgur.com/gallery/1NKzh
I've also been having these issues with grub. https://imgur.com/gallery/nQRtD

Ok looks like grub crashes. I have a guess for that.

But first - you did all that stuff after chrooting in the new gentoo-system first I hope? It's nowhere said but important, so just asking once.

I noticed that you have an EFI-directory in /boot. You are on a UEFI platform, correct? That means you need to setup grub for that. Just my guess - but I assume that could be the reason why grub crashes. There is a Wiki for that here where you can read about it: https://wiki.gentoo.org/wiki/GRUB2

Do this only if you are on an UEFI-Platform and grub is not setup already for that:
First you need to add this to your /etc/portage/make.conf:
Code:

GRUB_PLATFORMS="<your platform>"


Then you need to reemerge grub:
Code:

emerge --ask --newuse --deep sys-boot/grub:2


Then read under "UEFI with GPT".
It means that your partition layout should be GPT. (If your partition layout is different please post here.)

You need to mount the boot device if not mounted already and then install grub again.
Code:

grub-install --efi-directory=/boot/EFI


That's a template that fits for my system. Please check the wiki.
If grub installed correctly you should find a grubXXX.efi file under EFI/gentoo.

At last you can refresh grub.cfg again:
Code:

grub-mkconfig -o /boot/grub/grub.cfg


The warning you get there is not important because you don't use LVM. lvmetad is a service that is not running because you don't use LVM later.

Yeah, it seems that I missed that.

@nottobay

Since kernel vmlinuz supports UEFI with ESP (EFI System Partition) you may consider efibootmgr and write entries directly to EFI.

Tyrus, I have been doing the chroot each time. I've tried your suggestions and it still doesn't work.

Can you please try this;

Code:

parted -a optimal /dev/sda


And then use the following commands:
print
quit

I would like to see the output of print. Just to see your partition layout and the flags.

Other question do you have a grub*.efi file now? You checked that?

Thanks for your help. When I was emerging parted I ran into about a screen full of dependency issues, so I've desided to just reinstall from scratch.
