Upon booting my Dell XPS 15 9560 running Arch, I am being dropped into an emergency shell because my devices aren't being found
starting version 239 A password is required to access the luks volume: mount: /new_root: special device /dev/mapper/vg0-root does not exist. 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 ]#

That output is really confusing because it shows that vg0-root and vg0-swap both exist, but they just don't appear under dev, including after doing a
cryptsetup luksOpen /dev/nvme0n1p3 luks
My guess would be that I'm missing a hook with my mkinitcpio.conf, but this is my mkinitcpio.conf
HOOKS=(base udev autodetect modconf block encrypt lvm2 filesystems keyboard fsck)
Which I don't believe is any different from 5 days ago, the last time it booted just fine. I did run a
pacman -Syu earlier today, but I'm not sure how I would find out what exactly broke here.
mkinitcpio -p linux works without errors when chrooted into the drive from a arch usb
root=/dev/mapper/luks to my
GRUB_CMDLINE_LINUX, and now get the error
mount: /new_root: unknown filesystem type LVM2_member'
lvm vgchange -ay vg0
mount /dev/mapper/vg0-root /new_root
Allowed me to boot into my system, but this should be happening automatically with the lvm2 hook and upon restarting, I have to do it again.
