Доброго.
Ставится gentoo на lvm+raid1
Boot раздел отсутствует, вот схема устройств:
rescue / # lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 2.7T 0 disk

Усрановлен grub
[ebuild R ~] sys-boot/grub-2.00_p5086:2 USE="device-mapper multislot nls -custom-cflags -debug -doc -efiemu -libzfs -mount -sdl -static {-test} -truetype" GRUB_PLATFORMS="coreboot pc -efi-32 -efi-64 -emu -ieee1275 -multiboot -qemu -qemu-mips -yeeloong" 0 kB
Теперь сама проблема. Запускаю установку grub и ступор:
rescue / # grub2-install --modules="lvm raid mdraid1x reiserfs" --no-floppy /dev/sda
Path `/boot/grub2' is not readable by GRUB on boot. Installation is impossible. Aborting.
А до этого тоже конфиг ругался:
rescue / # grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub.cfg ...

done
Отдельно проба и тоже самое:
rescue / # grub2-probe -v -t fs /boot/grub2
grub2-probe: info: cannot open `/boot/grub2/device.map': No such file or directory.
grub2-probe: info: changing current directory to /dev/mapper.
grub2-probe: info: /dev/dm-0 is an LVM.
mdadm: cannot open /dev/md0 : No such file or directory
grub2-probe: error: cannot open `/dev/md0 ': No such file or directory.
Как так? Ведь raid на месте:
rescue / # mdadm -D /dev/md0
/dev/md0:

Понять не могу.
Вопрос: как починить установку загрузчика?
Спасибо кто откликнется.
