Problem with booting to encrypted btrfs raid

[roland-5]

I have to encrypted disk with luks. First (nvme1n1) with two partition:

• boot (as FAT32)
• encrypted with luks btrfs with few subvolumes (main is called arch)

Second disk (nvme0n1) is directly encrypted with luks and through it there is only one partition, that I wasn't use previously.

I wanted to add second disk to first one with this configuration:

btrfs device add /dev/mapper/additionaldisk /
btrfs balance start -mconvert=raid1

I wanted data to stay in single profile to have more disk space for files.

My /etc/booster.yaml

universal: false
compression: zstd
mount_timeout: 0s
strip: true
extra_files: busybox,nvim
vconsole: true
enable_lvm: false
enable_mdraid: false
enable_zfs: false

And my /boot/loader/entries/arch.conf

title Arch Linux
linux /vmlinuz-linux
initrd /amd-ucode.img
initrd /booster-linux.img
options rd.luks.name=6e4c6f50-ab67-429e-b5d8-5ef53929f429=samsung root=UUID=726660ee-aab3-4025-aed5-3b58961f0616 rw rootflags=compress-force=zstd,discard=async,subvol=arch

I tried change arch.conf to:

options rd.luks.name=6e4c6f50-ab67-429e-b5d8-5ef53929f429=samsung root=UUID=726660ee-aab3-4025-aed5-3b58961f0616 rw rootflags=compress-force=zstd,discard=async,subvol=arch rd.luks.name=0d363017-ac94-458f-9fc0-803c6b114465=additionaldisk rw rootflags=compress-force=zstd,discard=async,subvol=arch

and

options rd.luks.name=0d363017-ac94-458f-9fc0-803c6b114465=additionaldisk rd.luks.name=6e4c6f50-ab67-429e-b5d8-5ef53929f429=samsung root=UUID=726660ee-aab3-4025-aed5-3b58961f0616 rw rootflags=compress-force=zstd,discard=async,subvol=arch

and tried to change enable_mdraid: to true but it fails always with problem like this after entering password for first disk that show

BTRFS error (devie dm-0): devid 1 uuid 623fb88c-925c-4bfb-ba9c-ebbd852a8e3d is missing
BTRFS error (devie dm-0): failed to read the system array:

I used from AUR booster-wip-git package - commit 1b3902f
