 |
|
Hi all,
Going through install process for Gentoo with LUKS/LVM, first by following Sakaki's EFI Install Guide then MoJo's 'Encrypted Gentoo Linux Install Tutorial | LVM - LUKS - Plymouth' on youtube.
At reboot, I get warning, in my previous post I understood i do not need to worry about it but here he it is anyway.
| Code: | WARNING: Failed to connect to lvmtad. Falling back to device scanning
Enter passphrase for /dev/sda3
|
After entering my password
| Code: |
device-mapper: reload ioctl on failed: invalid argument.
|
Every time i enter correct password I get that message and cannot log in.
/etc/fstab
| Code: |
/dev/sda2 /boot ext2 noatime 0 2
/dev/mapper/gentoo-root / ext4 defaults,rw,relatime,data=ordered 0 1
/dev/mapper/gentoo-home /home ext4 rw,relatime,data=ordered 0 2
/dev/mapper/gentoo-swap none swap defaults 0 0
|
/etc/default/grub
| Code: |
GRUB_PRELOAD_MODULES=lvm
GRUB_ENABLE_CRYPTODISK=y
GRUB_DEVICE=/dev/ram0
GRUB_CMDLINE_LINUX="crypt_root=/dev/sda3 real_root=/dev/mapper/gentoo-root rootfstype=ext4 dolvm quiet splash"
|
If anyone has any pointers, that would be great! |

| Is this a Kernel or LVM issue? Where can I go for further documentation? |

| I would start by enabling debug printing of the steps, so that you know which command triggers that message. My guess is that it is related to the cryptsetup phase, not the LVM phase. Have you checked that your kernel has the appropriate ciphers to access the LUKS device? |

Hello Hu,
Thanks for the reply, I guess I need to boot again with CD installer, and allow logging at boot.
How do i do this properly? Because I enabled rc logging in [/etc/rc.conf], after rebooting I am stuck at EFI boot screen with EFI shell and Device mapping table.
I don't even have option to enter password.
I'm wondering if I need to remount everything when booting from CD after initial install.
| Code: |
cryptsetup luksOpen /dev/sda3 gentoo
#Enter passphrase
mount /dev/mapper/gentoo-root /mnt/gentoo
mount --types proc /proc /mnt/gentoo/proc
mount --rbind /sys /mnt/gentoo/sys
mount --rbind /dev /mnt/gentoo/dev
chroot /mnt/gentoo /bin/bash

My install instructions I modified are as follows:

Perhaps you can see what/where i go wrong in install process? |

unfortunately it does not log anything at boot.

tallylog is full of @@@@@@ symbols.
with this in mind I decided to go ahead and emerge syslog-ng
after emerging sucesffuly I am unable to enable it.
| Code: |
livecd /var/log # rc-update syslog-ng add default
* rc-update: invalid command `syslog-ng'
|
What am i missing? |

| You have the parameters out of order. According to man rc-update, you should write rc-update add service runlevel, but you wrote rc-update service add runlevel. Swap the second and third parameters. |

Thanks for the reply, you were correct. I had it the wrong way around.
However, this isn't easy...
After adding syslog-ng as default run level and rebooting, rebooted I no longer get grub splash screen. Instead it starts in EUFI Interactive Shell v2.1 with mapping table.
No logging done in /var/log/, which is understandable because this path is within a LUKS - LVM.
Honestly, I think I'll go back to non-encrypted lvm... this is getting far to in the weeds... Every change seems to break something else. |

LVM on LUKS on a partition is a pretty common setup. I've used this before, even with the root filesystem inside the LVM. It requires an initramfs to unlock LUKS and then scan/activate/mount the LVM, but it was worth it for me to be able to resize filesystems readily.
Since the initramfs handles mounting/unlocking, it is also on the initramfs to provide any debugging output you may need to understand why it does not work.
If you're being stopped at the UEFI shell, then that says your bootloader isn't even starting Linux, so your initramfs is currently irrelevant. We need to understand why the bootloader no longer starts Linux, and fix that first. |

Hello Hu,
I decided to start again completely, this time with simpler profile so that compile times would be shorter.
Managed to do full install, reboot system, unlocked luks partion and finally log in with no issue.
This morning when I rebooted I was welcomed by EUFI Interactive Shell v2.1 with mapping table. again.

| If your firmware's shell is asking for input, that suggests it is not running Grub. How did you configure the system to run Grub as your bootloader? |

Umm like this?
| Code: |
$echo "sys-boot/grub:2 device-mapper" >> /etc/portage/package.use/sys-boot
$emerge -av grub
$mount /boot
$grub-install --target=x86_64-efi --efi-directory=/boot
$grub-mkconfig -o /boot/grub/grub.cfg
$rc-update add lvm default
|
After this i changed passwd, then ran reboot.
It rebooted, showed grub menu, then was able to log in.
Next day I boot machine and am welcomed with firmware's shell. I changed nothing after initial log in... |

| That suggests your system's firmware is silently resetting your boot preferences. That is unpleasant, and very system dependent. |

Ok, strange, but i'm running this within a VM.
VM software wasn;t changed between boots either. |
