Hello, I'm installing Arch Linux with LVM on LUKS encryption on my new laptop. The setup is similar to the one described in https://wiki.archlinux.org/title/Dm-...em#LVM_on_LUKS, with the only differences being that my EFI partition comes before the LUKS one, and I'm not using a separate home partition inside the LVM. I have gotten my setup working on another laptop & desktop using both UEFI and BIOS, but never tried it on an SSD until now. My new laptop uses an SSD (/dev/nvme0n1) and the setup doesn't seem to work on here even when I try to set everything up as I would normally (albeit using /dev/nvme0n1 instead of /dev/sda).

After setting up my OS as described in the Arch Wiki page, I reboot into the new system and get this error:

device /dev/vg0/root not found. Skipping fsck.
mount: /new_root: special device /dev/vg0/root does net exist

This leads me to believe the encrypt hook in my mkinitcpio is not working properly, because GRUB would be correct in being unable to find /dev/vg0/root if it hasn't decrypted /dev/nvme0n1p2 yet. Normally it would expect it to ask me for the password to do so, as it does on my other comptuers, but it does no such thing. I also tried adding the "allow-discards" option in my GRUB config in GRUB_CMDLINE_LINUX line, as I heard this may help with SSDs, but this did not change the situation.

Does anyone know what may be causing GRUB to skip / have trouble regarding the encrypt hook in my mkinitcpio.conf? Thank you in advance for any help you can provide, and please let me know what system info I should post if needed.

post the following of the arch installation.
/etc/mkinitcpio.conf
lsblk -f
grub.cfg

I re-did my steps to obtain those 3 files for you, and to my surprise, my system seems to be working now. I can only guess that maybe I was missing a dependency or made a careless typo. A bit anti-climatic, I know. In any case, thank you so much for reaching out to help!

No problem
