Error on boot opening LUKS (intermittent problem)

Hi guys,

I get an error on boot once in a while, probably once every two weeks.
Here's a screenshot of the error: https://imgur.com/v0qDcM6

Given it's intermittent and does not happen often, it's safe to assume it most likely related to my initramfs hooks order.

Some details...
BIOS, LVM on LUKS.

/dev/sdc1 contains boot partition
/dev/sdc2 is an encrypted (LUKS) partition with LVM volumes including:
   /dev/volgroup0/lv_root
   /dev/volgroup0/lv_home
   /dev/volgroup0/lv_swap

/etc/mkinitcpio.conf

MODULES=(ext4 nvidia atkbd)

HOOKS=(base udev autodetect keyboard keymap consolefont modconf block encrypt lvm2 resume filesystems fsck)

/etc/default/grub

GRUB_ENABLE_CRYPTODISK=y

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 cryptdevice=/dev/sdc2:volgroup0:allow-discards nvidia-drm.modeset=1 apparmor=1 lsm=lockdown,yama,apparmor quiet resume=/dev/volgroup0/lv_swap"

I'm not sure how close to the left I should shift 'encrypt'?
I read 'encrypt' and 'lvm2' to go between 'block filesystems'

Also I can get rid of consolefont, really don't need this.

Thanks.

Why aren't you setting the root parameter in your grub config?

I'm not sure!?!?! I thought I had the 'root' specified at one time. It probably got removed by a copy/paste somewhere along the line.
Thanks! Good spot!

See how I go in the next week or two... amending to:

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 cryptdevice=/dev/sdc2:volgroup0:allow-discards root=/dev/volgroup0/lv_root resume=/dev/volgroup0/lv_swap nvidia-drm.modeset=1 apparmor=1 lsm=lockdown,yama,apparmor quiet"

Thanks again!
