 |
|
I get the following error right after installing Gentoo: https://ibb.co/sV0ghBC
here is how Iencrypted it:
| Code: | cryptsetup luksFormat /dev/sda2
cryptsetup luksOpen --allow-discards /dev/sda2 hive
mkfs.ext4 /dev/mapper/hive |
Here is my /etc/fstab:
| Code: | /dev/sda1 /boot vfat defaults,noatime 0 2
/dev/mapper/hive / ext4 noatime 0 1 |
Here is my /etc/default/grub:
| Code: | GRUB_CMDLINE_LINUX="crypt_root=/dev/sda2 root=/dev/mapper/hive"
GRUB_CMDLINE_LINUX_DEFAULT=”root_trim=yes” |
Should I Use UUIDs ? |

I do not use an encrypted setup at the moment, so this could be wrong...
But as far as I remember /etc/default/grub should look something like this.
| Code: |
...
GRUB_CMDLINE_LINUX="crypt_root=/dev/sda2 rootfstype=ext4 real_root=/dev/mapper/hive"
...

I don't quite get what you mean...
I do:
| Code: | cryptsetup luksOpen --allow-discards /dev/sda2 hive
mount /dev/mapper/hive /mnt/gentoo |
and the rootfs files are in there... |

You do: Please "open" it with my invented name "hive" and then you mount it with this name. But this name isnt store anywhere ...

It means, some scripts dont "open" it with "hive", it is "/dev/mapper... " (and this is also only a link to the real /dev/dm-0 or /dev/dm-1) |

ok I messed things up badly...now when I turn my laptop on it doesn't find any bootable device...here is what I did:
| Code: | cryptsetup luksOpen /dev/sda2 hive
mkdir /mnt/gentoo
mount /dev/mapper/hive /mnt/gentoo
cd /mnt/gentoo
mount -o bind /proc /mnt/gentoo/proc
mount --rbind /sys /mnt/gentoo/sys
mount --make-rslave /mnt/gentoo/sys
mount --rbind /dev /mnt/gentoo/dev
mount --make-rslave /mnt/gentoo/dev
chroot /mnt/gentoo /bin/bash
env-update
source /etc/profile
export PS1="(chroot) $PS1"
mount /dev/sda1 /boot
genkernel --luks initramfs
nano -w /etc/default/grub
GRUB_CMDLINE_LINUX="crypt_root=/dev/sda2 rootfstype=ext4 real_root=/dev/mapper/hive"
grub-mkconfig -o /boot/grub/grub.cfg
------
exit
cd
umount -l /mnt/gentoo/dev{/shm,/pts,}
umount -R /mnt/gentoo
reboot or poweroff |
I also get this error when grub-mkconfiging:
| Code: | | WARNING: Failed to connect to lvmetad. |
| Quote: | | It means, some scripts dont "open" it with "hive", it is "/dev/mapper... " (and this is also only a link to the real /dev/dm-0 or /dev/dm-1) |
so, this is the correct line? :
| Code: | | GRUB_CMDLINE_LINUX="crypt_root=/dev/sda2 rootfstype=ext4 real_root=/dev/mapper..." |

Oh, no. I wrote "..." as meaning the rest of the directory. |

ok, here is what its showing:
https://ibb.co/G2nMBZk
so the line should be this:
GRUB_CMDLINE_LINUX="crypt_root=/dev/sda2 rootfstype=ext4 real_root=/dev/mapper/root"
can someone confirm ? |

ok, it works now...
I have another question:
when I do grub-mkconfig, I get the following warning:
| Code: | | WARNING: Failed to connect to lvmetad. |
I am not using lvm but I created my initramfs with
| Code: | | genkernel --microcode --luks --lvm initramfs |
how do i get rid of this warning ? |
