[SOLVED] Timed Out Waiting For Device Grub + Luks Encryption

I did pacman -Syu..... now my systems borked

Long story short, I repartitioned my boot and efi partitions and reinstalled grub however it can no longer recognize my encrypted partition

Pic of the error:

lsblk:

nvme0n1                                   259:0    0 476.9G  0 disk

/etc/fstab:

HOOKS for mkinitcpio.conf:

HOOKS=(base systemd autodetect microcode modconf kms keyboard keymap sd-vconsole block sd-encrypt lvm2 filesystems fsck)

The relevant part of /etc/default/grub:

# GRUB boot loader configuration

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Arch"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX="root=/dev/mapper/volgroup0-lv_root"

# Preload both GPT and MBR modules so that they are not missed
GRUB_PRELOAD_MODULES="part_gpt part_msdos"

# Uncomment to enable booting from LUKS encrypted devices
GRUB_ENABLE_CRYPTODISK=y

This problem feels like I' m just being stupid but Ive been stuck on this for way too long.

Re: [SOLVED] Timed Out Waiting For Device Grub + Luks Encryption

your missing:

rd.luks.name=device-UUID=luks

from your GRUB_CMDLINE_LINUX (i used 'luks' as thats what you appear to be using), you need to get the UUID of the luks container using

lsblk -f |grep nvme0n1p3 

and replace 'device-UUID' with it

also

root=/dev/mapper/volgroup0-lv_root

is not required here as grub takes care of that itself when you run grub-mkconfig

also check your fstab against the output of

lsblk -f

and make sure theyre all correct

after all thats done run grub-mkconfig and mkinitcpio and it SHOULD work
