[SOLVED] Extending Root LVM is breaking GRUB

Hello everyone,

I have successfully installed Arch Linux with UEFI and LVM on 2 machines following the wiki guide: https://wiki.archlinux.org/index.php/In … nux_on_LVM

On the first machine I formatted the drive with an EFI partition (fat32) a root partition (ext4), a home partition (ext4) and a swapfile. I then added a new disk, created a partition (ext4) and extended the LVM home partition, everything worked fine.
On the second machine I have an EFI partition (fat32) a root partition (ext4) and a swapfile. I added a new disk to this machine, created a partition (ext4) and extended the root LVM partition, but when rebooting GRUB goes into rescue mode (lvmid/... is not found).
Lvdisplay and vgdisplay are displaying the UUID reported by GRUB.

Can someone point me in the right direction?

Thanks.
Guilli

I found the solution. The EFI partition should be mounted under /boot instead of /boot/efi.
Problem solved for me.
