Не поднимается LVM зеркало при загрузке

Текущий релиз Arch

ос была проинсталлирована на /dev/sdb2 , затем сделал lvconvert -m1 чтобы получить заркало на sda2, lvconvert сообщил что все отлично и будет raid1 resilency

так создавал

vgextend vg /dev/sda2
lvconvert -m1 vg/root

это получил

установил grub в esp , само ядро лежит на lvm. Конфиг grub

cat /efi/grub/grub.cfg

menuentry 'Arch Linux, with Linux linux' {
 ..
        set root='lvmid/1YMttW-DhDc-Sk9s-QuyC-tEIM-iY75-xqj8aW/192Is5-CAez-XEwC-c1ZN-cn1z-doKd-WbB9Zc'
 ..
        echo    'Loading Linux linux ...'
        linux   /boot/vmlinuz-linux root=/dev/mapper/vg-root rw  loglevel=3
        echo    'Loading initial ramdisk ...'
        initrd  /boot/initramfs-linux.img
}

скопировал содержимое efi system между обоими дисками, добавил ссылки на загрузчики в nvram

efibootmgr -c -b 1 -d /dev/sdb -p 1 -L "GRUB 1" -l "\EFI\GRUB\grubx64.efi"
efibootmgr -c -b 2 -d /dev/sda -p 1 -L "GRUB 2" -l "\EFI\GRUB\grubx64.efi"

т.е. должны получить возможность загрузится с любого диска при отказе одного. Так как на каждом идентичные ESP с загрузчиком и raid1 lvm. С двумя дисками без проблем загружаюсь с обоих загрузчиков меняя в bios порядок загрузки, часть с grub работает. Проблемы начинаются когда я отключаю целиком один диск. Загрузчик оставшегося запускает ядро но получаем

waiting for root device /dev/mapper/vg-root

и вываливаемся в консоль initrd без рута

ls /dev/mapper control .. пусто

в dmesg ошибок нет, он как будто и не пытался lvm том поднять pvs , vgs показывают что половинка lvm им видна, ругаются на disk missing том в статусе partial, тут все верно.

вопрос, почему не поднимается доступная половинка зеркала в рут и не идет загрузка? повторюсь, если оба диска подключены все работает отлично, при отключении любого из них все встает
