LVMonLUKS, GPT/UEFI, won't start after installation

General system EndeavourOS installation
1

Hi All
Fresh Installation of EndeavourOS on VirtualBox, LVM on LUKS, GPT, UEFI

/dev/sda1 /boot/efi 320MiB Fat32 Efi System
/dev/sda2 /boot 1GiB ext4
/dev/sda3 LVMonLUKS
/dev/vg0/root / ext4
/dev/vg0/home /home ext4
/dev/vg0/swap
  1. Due to Calamares closes LUKS and/or LVM device before trying to install to it
    To install system used script
while true
do
vgchange -ay
done

Then install with Calamares

  1. However, after installation have something like that
ERROR: device '/dev/mapper/vg0-root' not found, Skipping fsck.
mount: /new_root: special device /dev/mapper/vg0-root does not exist.
You are now being dropped into an emergency shell.
sh: can't access tty; job control turned off
[rootfs ]#

Most probably grub need to be updated due to problem that it use /dev/disk/by-uuid instead of /dev/sda. I can change file grub.cfg, but what is next, how to chroot the system to update grub configuration.

thank you all for welcoming)
Do you need to use tutorial to install LVM on LUKS? :blush:
No, i did not.

So, I sorted it out.
What was done

sudo su

  1. Mount from live
mount /dev/mapper/vg0-root /mnt
mkdir -p /mnt/boot/efi
mount /dev/sda1 /mnt/boot
mount /dev/sda1 /mnt/boot/efi
mkdir -p /mnt/home
mount /dev/mapper/vg0-home /mnt/home
  1. Change the HOOKS=… line by adding encrypt and resume
xed /mnt/etc/mkinitcpio.conf
HOOKS="base udev autodetect modconf block keyboard keymap encrypt lvm2 resume filesystems fsck"
  1. Change default grub
xed /mnt/etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="audit=0 loglevel=3"
GRUB_CMDLINE_LINUX="cryptdevice=/dev/disk/by-uuid/YOUR_UUID:cryptlvm:allow-discards rd.luks.options=discard"
GRUB_ENABLE_CRYPTODISK=y
  1. and finally, looked in nearest same topic, update grub.cfg file
arch-chroot /mnt
mkinitcpio -p linux
grub-mkconfig -o /boot/grub/grub.cfg
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=EndeavourOS-grub
rm -rf /boot/efi/EFI/EndeavourOS
cp /boot/efi/EFI/EndeavourOS-grub/grubx64.efi /boot/efi/EFI/boot/bootx64.efi
exit
  1. Unmount and reboot
umount -R /mnt
reboot
