[SOLVED] Problems with software raid, LVM, UEFI

Update: The EFI-partition don't needs to be in RAID-1. I have now created two EFI-partition on both the HDD's and sync them. The only thing I could think of is creating two efibootmgr entries and change the /etc/fstab when removing one HDD. If someone also have issues with EFI please let me know what you did! Thanks!

Hi!

I hope someone can help me. I'm trying to get my (new) systeem to boot UEFI.
This is my first experience with LVM and software raid-1.

I have found most of the information from the Arch Wiki's.

Problems:
- After installation systeem doesnt boot: "Please enter a valid system disk.. or reboot.."

Questions:
- Do I need to use /dev/mapper/* for boot?
- Are the given steps correctly? (Is the bootloader partition also a df00?)

Thanks!

This are the steps I have used to install ArchLinux:

Raid 1:
Switch TTY
mdadm --zero-superblock /dev/sd[ab]

partprobe -s
modprobe raid1
modprobe dm-mod

/dev/sda2	/boot	+100M	fd00
/dev/sda3	swap	+2048M	fd00
/dev/sda4	/	*	fd00
sgdisk --backup=table /dev/sda
sgdisk --load-backup=table /dev/sdb
mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sd[ab]4
