최근에 Arch Linux 설치를 업데이트했습니다. 나는 이것을 2주에 한 번씩 하려고 노력한다. 완료되면 재부팅하고 /home(내 홈 파티션)에 대한 종속성이 실패했다는 오류를 받았습니다. 시작 프로세스가 즉시 비상 모드로 전환됩니다. 내 홈 파티션이 전혀 마운트되지 않은 것을 발견했습니다. 이상하게도 패닉 모드로 들어갔다가 나갈 수 있습니다. 그 후 기본 파티션이 마운트되고 시스템이 정상적으로 로드됩니다.
내 기본 파티션은 다음과 같습니다.BTFS그리고 내 루트 파티션은확장 4./etc/mkinitcpio.conf내 파일에는 시작 시 btrfs를 검색하는 HOOK가 있습니다 . 작동 중이며 스캔 중인 btrfs가 출력되는 것을 볼 수 있습니다.
출력을 확인하라는 메시지가 표시되지만 journalctl -xb홈 파티션이 마운트되지 않은 이유를 이해할 수 없습니다.
내 파일에서 기본 파티션의 UUID를 확인하라는 유사한 게시물을 읽었습니다 /etc/fstab. 내 fstab 파일의 모든 내용은 괜찮아 보였지만 아치 마운트 USB를 넣고 파일을 재생성하기로 결정했습니다. 문제가 해결되지 않았습니다.
이것은 내 Journalctl -xb 출력의 일부입니다.

영구적인 해결책은 BTRFS 파티션의 모든 것을 복사하고 EXT4로 다시 포맷한 다음 파일을 다시 넣는 것입니다. 시간이 많이 걸리기 때문에 꼭 하고 싶은 것은 아니지만, 꼭 해야 할 일일 수도 있습니다.
어떤 도움이라도 대단히 감사하겠습니다. 제가 아는 모든 것을 시도해 본 것 같습니다.
다른 출력이나 로그가 필요한 경우 알려주시기 바랍니다.

"/home" 항목 -netdev에 옵션을 추가합니다 . fstab설치된 종속성은 네트워크 관리 스택인 것으로 보입니다.
