이런, 시스템을 부팅한 지 1분 후에 파티션이 ro다시 모드로 전환되었습니다.
$ mount | grep home

답변1
btrfs check /dev/sdb1근본 원인을 밝히는 것이 좋습니다. 마운트 해제된 파일 시스템에서
답변2
좋아, 나는 내 문제가 내 직감 때문에 발생했다는 것을 알아낸 것 같다 syncthing. 그리고 내 손에는 분명히 방향을 가리킬 수 있는 어떤 논리적인 것도 없다. 문제의 자세한 원인이 무엇인지 알고 싶습니다. 누구든지 저를 도와주실 수 있다면 정말 좋을 것 같습니다!
비활성화하면 성능이 향상되었을 뿐 문제가 해결되지 않은 것으로 나타났습니다 syncthing. 즉, 아직 해결되지 않았습니다!
