It's my first post, i'm in trouble, i updated a configuration of Arch from ext4 lvm+LUKS (working) to btrfs with UEFI GRUB.
I get a message error at boot:
error: no such device 535592fe (UUID)
error unkown filesystem
Entering rescue mode
grub rescue >
The error tell me a UUID which is /dev/mapper/root of my encrypted partition.
All my procedure of installation manual is on a gist to this link: https://gist.github.com/legoffant/0a90e … 28a8a4a356
Someone could check it and find the error, i try to see if it was partitionning, fstab then hook for kernel or edit maybe my /etc/default/grub.
I've try many change with all time the same error
So i've installed then with archinstall script i get passed grub recognize the disk encrypted but give me a error to write the passphrase, i think doesnt recognize my keyboard in french Azerty.

Post your /boot/grub/grub.cfg, does it include the fact that you'd need to boot a specific subvol now? Did you reinstall the GRUB payload by rerunning the grub-install command so it knows to include BTRFS support?

I have included btrfs support in initramfs.
I will try a install with systemd-boot, i hope is better, grub is so much overkill
