 Posted: Mon Jul 18, 2022 5:04 pm Post subject: OpenRC doesn't start at boot |
 |
|
Hello, Gentoo Forum!
Just started using Gentoo a couple of weeks ago. I am no longer able to boot my SSD. I can see the pre-Open RC output from the boot sequence and I get the prompt to enter the password to decrypt my SSD.
Once I decrypt the drive, nothing else happens. I am able to see text I enter at the command line, but no RC scripts execute, and thus I have no shell.
I haven't modified my crypttab, fstab, or grub config since they worked. I tried booting from a new kernel and a confirmed working kernel (doesn't seem to be a kernel issue, but what do I know?) to the same result.
Please let me know what other info to provide to see what the issue is.
EDIT: probably also relevant to mention that I can decrypt and mount the SSD partition from the Gentoo live CD. |

burningserenity,
Welcome to Gentoo.
I suspect that you have lost the console output for some reason.
That is, everything is working normally but you can't see it.
Post the output of
Make friends with wgetpaste and use it to put your kernel .config file onto a pastebin site, then post the link you get back so we can see it.
If you have another system and you set up sshd while you are in the chroot, you may find that you can log in over ssh and wgetpaste tho output of the dmesg command.
That may have some useful error messages.

burningserenity,
dmesg looks good. Its using the EFI framebuffer to start then switches to i915drmfb.

Its not from the kernel config you posted, as that says ... | Code: | #

Your kernel has We know that works to get you started.
and That drivel needs firmware, witch is provided by linux-firmware.
It must be loaded from the initrd. You do have an initrd as you are using an encrypted root.
Tell how you configure, build and install your kernel and its matching initrd.

| What is the initrd, exactly? I use portage to handle kernel installation, using savedconfig. I use dracut to create the initramfs. |

initrd is what used to be used instead of initramfs. Some people use the terms interchangeably today even if they are not exactly the same internal structure. They share the same purpose. |

burningserenity,
The initrd is a small root filesystem in a file.
Its loaded by your boot loader or even built into the kernel.
Its supposed to contain everything needed to mount the root filesystem, that cannot be built into the kernel.
It also contains kernel modules, which is what binds it to a specific kernel.
The kernel checks the 'version magic' for bits of itself and will not load mismatching modules.
dracut has a good reputation. I don't use it but there are very few reported problems with it here.
Portage does not handle kernel installation, at least, not the way I mean. It puts the sources into /usr/src.
Then its up to you.
What commands do you use to get your kernel from /usr/src into /boot with its matching initrd, then tell the boot loader all about it so you can use it?

burningserenity,
That makes life easy, as you say, its all controlled by portage.
That's the kernel. What about the intrd/iniramfs and putting everything into /boot, so the boot loader can find it.?
I'm one of these people that grknight warned you about. :)

| The initramfs is made by dracut and is triggered by portage. I believe dracut copies over the images to /boot. I manually run `grub-mkconfig -o /boot/grub/grub.cfg` each time after I install a new kernel. |

| The kernel is installed via installkernel, per portage output. |

| I found that if I wait long enough on boot, dracut errors with `/dev/mapper/root` does not exist. |

burningserenity,
Either your low level block device driver is missing or LVM in the initrd/initramfs fails to start.
You have | Code: | 00:17.0 SATA controller [0106]: Intel Corporation Cannon Lake Mobile PCH SATA AHCI Controller [8086:a353] (rev 10)
DeviceName: Onboard - SATA
Subsystem: CLEVO/KAPOK Computer Cannon Lake Mobile PCH SATA AHCI Controller [1558:95e1]
Kernel driver in use: ahci
02:00.0 Non-Volatile memory controller [0108]: Samsung Electronics Co Ltd NVMe SSD Controller SM951/PM951 [144d:a802] (rev 01)
Subsystem: Samsung Electronics Co Ltd PM963 2.5" NVMe PCIe SSD [144d:a801]
Kernel driver in use: nvme |
for block device support.
Are they both available in the kernel?
With dracut, modules will work.
What about Multiple Disk support?
That's the kernel part of LVM?
I suspect that dracut needs to be told to include LVM support but I've never used it.

I switched to the binary kernel till this is resolved, to simplify things, so it has all that stuff loaded.
Adding the lvm module to dracut did not work.
What did work was getting to the dracut rescue console, remounting my crypt root as /dev/mapper/root (it's mounted as /dev/mapper/luks-<hex>), then exiting the dracut console.
Now my question is, how do I get dracut to initially mount my crypt root properly like it did before? |

burningserenity,
I can't help with dracut. Now you have a different question, start a new topic. You will get more helpers that way.
Refer to this topic for the history.
