부팅 시 외부 USB 3 HDD(Seagate Backup Plus 1T)가 연결된 경우 Debian 테스트 시스템의 Initramfs가 필요한 커널 모듈을 자동으로 로드하지 못합니다. initramfs 쉘로 부팅하면 케이블을 뽑았다가 다시 연결하면 장치가 표시되고 마운트할 수 있습니다.
initramfs에는 이 장치가 필요하지 않지만 /dev/initramfs에 의해 생성된 파일 시스템은 필요한 기본 OS로 전달됩니다. 장치를 사용하려면 케이블을 꽂았다가 뽑아야 합니다.
이 장치를 마운트하기 위해 initramfs를 어떻게 설정합니까?아니면 하드웨어 버스를 통과하여 udev가 놓친 initramfs의 모든 장치를 처리하도록 기본 OS에 어떻게 지시합니까?
추가 정보
장치를 껐다가 켜면 두 개의 새 모듈이 로드됩니다.

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

디스크가 컴퓨터의 USB 3 포트에 연결되어 있는지 아니면 USB 2 포트에 연결되어 있는지는 중요하지 않습니다.
initramfs 초기화 전에 연결된 USB2 장치가 올바르게 인식되고 설정됩니다. 다른 USB 3 장치도 영향을 받는지 확인할 수 없습니다. 그러나 친구의 컴퓨터(Ubuntu 16.04 사용)에서 이 디스크를 사용해 볼 수 있었습니다. /dev/부팅 후 문제가 해결되어 작동했습니다.
initramfs-tools를 통해 또는 dracut을 통해 initramfs를 생성하는지 여부는 중요하지 않습니다.
/dev/sdb*부팅하기 전에 케이블이 연결되어 있더라도 완전히 부팅된 시스템에서 이 HDD와 관련된 콘텐츠를 사용할 수 있도록 하려면 어떻게 해야 합니까?
답변1
글쎄, 이것은 터무니없는 추측이자 해결 방법(그리고 문제에 대한 적절한 이해가 아님)이지만 작동할 것입니다.
예를 들어 udev규칙 파일을 만들고 /etc/udev/rules.d/z30-seagate-disk.rules다음 규칙을 추가합니다.
ATTRS{manufacturer}=="Seagate", ATTRS{product}=="BUP Slim BK", SYMLINK+="seagate"
이렇게 하면 두 번째 패스가 강제 실행 udev되고 디스크가 /dev/seagate블록 장치로 추가됩니다. 또한 파일 을 FILES변수 /etc/mkinitcpio.conf에 추가하여 initramfs.mkinitcpio -p linuxinitramfs
면책 조항: Debian이 아닌 Arch에서 테스트되었으며 USB 3.0을 사용하지 않았습니다.
uas또 다른 해결 방법은 (USB SCSI)가 항상 커널에 의해 로드되도록 강제하는 것입니다 . 파일에 추가하고 /etc/modules-load.d/seagate-disk.conf모듈 이름을 말하십시오.
uas
usb_storage
usbcore
scsi_mod
usb_common
이론적으로는 그게 전부 uas이지만 문제를 재현할 수 없으므로 USB HDD를 관리하는 데 필요한 모든 것을 무차별 대입하려고 노력할 것입니다. FILES에 파일을 다시 추가하십시오 /etc/mkinitcpio.conf.
이렇게 하면 커널이 uas항상 로드됩니다. 아마도 버스를 통해 실행될 때 udev커널이 USB 모듈을 로드하지 않기 때문에 USB 허브/버스에 아무것도 로드되지 않았다고 잘못 가정할 수 있습니다.
답변2
포함을 편집 /etc/modules하고 추가합니다 uas.
그런 다음 실행합니다 update-initramfs(예: 현재 실행 중인 커널 또는 설치된 모든 커널의 initramfs 업데이트 update-initramfs -u -k $(uname -r)).-k all
/etc/modulesudev나열된 모듈은 해당 모듈이 필요하다는 것을 다른 것이 감지하는지 여부에 관계없이 자동으로 로드됩니다.
이는 모듈이 로드되는 특정 순서를 강제로 적용하려는 경우에도 유용합니다. 따라서 이 모듈은 foo항상 모듈보다 먼저 로드됩니다 bar(물론 이전에 로드된 모듈이 이에 의존하지 않는 한 bar).
로드하는 모든 모듈과 마찬가지로 modprobe파일에서 로드 시간 옵션을 설정할 수 있습니다 /etc/modprobe.d/.
예를 들어 다음과 같은 합계를 나열했습니다 spl.zfs/etc/modules/etc/modprobe.d/zfs.conf
# use minimum 4GB and maxmum of 8GB RAM for ZFS ARC
options zfs zfs_arc_min=4294967296 zfs_arc_max=8589934592
