저는 현재 NVME 500Gb SSD를 사용하는 새 컴퓨터에서 젠투를 구성하고 있습니다.
컴퓨터를 다시 시작하고 부팅할 디스크를 선택하고 grub2를 초기화했습니다.그런 다음, 내가 얻는 오류는 다음과 같습니다.
!!Block device UUID="9a89bdb4-8f36-4aa6-a4c7-831943b0985c" is not a valid root device...
!!Could not find the root block device in UUID="9a89bdb4-8f36-4aa6-a4c7-831943b0985c"

마지막으로 내 콘텐츠는 다음과 같습니다 etc/fstab.
# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed); notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# See the manpage fstab(5) for more information.
#
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
#
# NOTE: Even though we list ext4 as the type here, it will work with ext2/ext3
# filesystems. This just tells the kernel to use the ext4 driver.
#
# NOTE: You can use full paths to devices like /dev/sda3, but it is often
# more reliable to use filesystem labels or UUIDs. See your filesystem
# documentation for details on setting a label. To obtain the UUID, use

또한 다음 문제 해결 작업도 수행했습니다.
- 커널에서 NVME 지원 활성화
- 커널에서 xfs 파일 시스템 지원 활성화
- rootfstype=xfs 없이 grub 로드

이는 GRUB 생성 메시지처럼 보이지 않습니다.
GRUB가 실제로는 잘 작동하지만 initramfs에 NVMe 드라이버나 GPT 파티션 유형 지원 모듈과 같은 일부 필수 항목이 누락되었을 수도 있습니다(물론 커널에 모두 내장하지 않은 경우). 그렇다면 Gentoo initramfs가 일종의 문제 해결 모드로 충돌할 수도 있을까요?
Gentoo에는 initramfs 파일을 생성하는 여러 가지 방법이 있는 것 같습니다. genkernel이렇게 할 수 있습니다. 아니면 dracut.
shell이 프롬프트를 입력 하고 /dev/nvme*장치 노드가 존재하는지, 어떤 커널 모듈이 로드되었는지 등을 확인해야 할 수도 있습니다. initramfs 생성 유틸리티에 내장된 NVMe 시스템 디스크에 대한 특정 지원이 아직 없는 경우 유틸리티에 " nvme-core.ko루트 파일 시스템을 찾으려고 하기 전에 initramfs 모듈을 로드해야 합니다"라고 알려주는 nvme.ko것만 큼 간단할 수 있습니다. 자동으로 나옵니다.
