 Posted: Thu Mar 07, 2024 4:15 pm Post subject: bottim stuck at start job is running for /dev/mapper/root |
 |
|
so hello i tried installing after few years encrypted gentoo installation i went little bit off normal course, so i have one disk
/dev/sda1 EFI boot mounted at /efi
/dev/sda2 swap
/dev/sda3 Luks encryption NO LVM inside it only ext4 partition inside,
and i can easily open my partition arch-chroot inside it with no problem but it wont boot,
this is what is see when i boot it
my fstab is but i also tried insdead of PARTUIID of /dev/sda3 replacing it with /dev/mapper/cryptroot
and this is my /etc/grub/default
also my make.conf
but i dont think i changed anything else
keep in mind i dont use LVM inside so ijust
| Code: |
cryptsetup luksOpen /dev/sda3 cryproot
mount /dev/mapper/cryptroot /mnt/gentoo
#and it works
|
what did i do wrong? i use gentoo-kernel-bin and otherwise i just have plasma desktop which i had no chance to test yet |

Fix the grub config changing cryptdevice=UUID= to rd.luks.name= and change :cryptroot to =cryptroot on the end of that parameter as well.
Edit: changed advice based on new information |

thank you for the fast reply, howere i couldnt find more info on that command rd.luks.name, but i tried it but same problem i tried waiting 120 seconds now, and it still wouldnt mount
did i do it correclty? ignore the blkid at the bottom i was just verifying, after editing that config i ran
| Code: |
grub-install for efi into /efi directory
and grub-mkconfig to /boot/grub/grub.cfg
|
not sure how to diagnose this further i thought this simple setup would be simple to set up |

Try also adding rd.auto=1 to the kernel command-line (like GRUB_CMDLINE_LINUX).
gentoo-kernel-bin uses dracut for its initramfs so options for unlocking LUKS must be interpreted by dracut. |

so i found out some new info, its behavior is very weird when i input no passowrd and it doesnt seem to unlock my luks partition when asking for passphrase and is it fine it asks for my pass before grub even loads?

Not sure if I understand you correctly. The kernel is stored under /boot which is on your /-partition. Because it is encrypted, Grub needs to unlock your LUKS container to be able to read the /boot/grub/grub.cfg. So it is normal to be asked for the password before it can show the boot menu.
If you did not want an encrypted /boot, then you need an unencrypted /boot its own partition (you could use the ESP as /boot). In this case Grub does not need to unlock a LUKS container and can load the kernel and initramfs (and GRUB_ENABLE_CRYPTODISK is not needed/used).
Can you please share to see the USE flags? |

| Did you rebuild the initramfs after adding cryptsetup to systemd? |

The USE flag cryptsetup for systemd pulls in sys-fs/cryptsetup. Dracut is then adding the module "crypt" if it finds sys-fs/cryptsetup installed.
I watched the two videos today. The Grub video is correct, you enter the LUKS passphrase and Grub is successfully unlocking the LUKS container and loading the grub.cfg.
The video with the dracut/initramfs part is not ok. In the video it tries to mount /dev/mapper/root, but you are never asked to enter the LUKS passphrase prior to mount /dev/mapper/root.
Can you please show the /boot/grub/grub.cfg (please as text)? And I would also rebuild the initramfs with Dracut:
| Code: | # as an example, adjust the values
dracut --force --logfile=/tmp/dracut.txt initramfs-6.6.13-gentoo.img 6.6.13-gentoo
# | | | \ name of the kernel (uname -r)
# | | \ name of the initramfs in /boot
# | \ store the output in a logfile to share
# \ if the initramfs already exists, force the creation
|
I am using gentoo-sources and I do not know, which dracut command gentoo-kernel-bin is using. |

yes the proble was with me not rebuilding kernel with emerge -a --config gentoo-kenrelbin i did that now it works, but well it asks for my passhphrae 3 TIMES !!!!
1. before grub shows which is fine
then 2 times in systemd, first for unlokcing UID of /dev/sda3 a
and the third time for unlocking /dev/mapper/root? what the hell,,
and i couldnt share my cfg as text because i couldnt login :d now i can and will post soon as soon i compile firefox |

| Entering the LUKS passphrase twice is expected. 3 times is not normal. |

ye three times look here
one before grub and after grub like this
but well after this it worked, so iwas in system was installing firefox and dolphin but hardware accelartion wasnt working, i have nvidia quadro K2200 so i masked nvidia propertiary driver versin 470 and remerge did emerge --config gentoo-kernel-bin and did grub again, but now i cant boot
i got this error very werid i am not sure why and how this happened, it was fine this morning, should i jus use normal open source driver? i would benefit from the performacne of the propetiary one |
