저는 현재 NVME 500Gb SSD를 사용하는 새 컴퓨터에서 젠투를 구성하고 있습니다.
컴퓨터를 재부팅하고, 부팅하려는 디스크를 선택하고, grub2가 초기화됩니다.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 내용은 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
# the blkid(8) command.

또한 문제 해결을 위해 다음을 수행했습니다.
- 커널에서 nvme 지원 활성화
- 커널에서 xfs 파일 시스템 지원을 활성화합니다.
- rootfstype=xfs 없이 grub 로드

GRUB에서 생성된 메시지처럼 보이지 않습니다.
아마도 GRUB는 실제로는 잘 작동하지만 initramfs에 NVMe 드라이버나 GPT 파티션 유형 지원 모듈과 같은 필수 요소가 누락되었을 수도 있습니다(물론 커널에 고정된 대로 모두 구축하지 않은 경우). 그렇다면 아마도 일종의 문제 해결 모드에 충돌하는 것은 Gentoo initramfs일까요?
Gentoo에는 initramfs 파일을 생성하는 여러 가지 방법이 있는 것 같습니다. genkernel그렇게 할 수도 있고, dracut. 어느 것을 사용하고 있습니까?
해당 프롬프트에 입력하고 장치 노드가 있는지, 어떤 커널 모듈이 로드되었는지 등을 shell살펴볼 수 있습니다 /dev/nvme*. initramfs 생성자 유틸리티에 아직 내장된 NVMe 시스템 디스크에 대한 특정 지원이 없는 경우, 유틸리티에 "initramfs는 루트 파일 시스템을 찾으려고 하기 전에 nvme-core.ko및 모듈을 로드해야 합니다"라고 지시하면 되는 것처럼 간단할 수도 있습니다 . nvme.ko자동으로 알아내지 못할 수도 있습니다.
