저는 OpenSuSE Tumbleweed를 사용하고 있으며 다음 디스크를 가지고 있습니다:
- /dev/sda1:/home (btrfs)
- /dev/sdb1:/start
- /dev/sdb2: 스왑
- /dev/sdb3: / (btrfs)
컴퓨터를 부팅하면 systemd가 디스크를 마운트하려고 시도하지만 시간이 초과됩니다. 시스템이 복구 모드로 부팅됩니다. /dev/sda1을 /mnt에 수동으로 마운트하려고 시도했을 때 아무런 문제 없이 성공적으로 작동했습니다. 그러나 이렇게 하면 mount /dev/sda1 /home명령은 성공하지만 아무것도 설치되지 않습니다. 또한 systemd는 때때로 10분 정도 후에 디스크를 성공적으로 마운트하지만 항상 그런 것은 아닙니다. 그렇다면 문제 없이 계속 부팅할 수 있습니다. 로그에는 다음 메시지가 포함되어 있습니다.

그러나 복원 재배치가 무엇을 하는지, 왜 멈추는지 솔직히 전혀 모르겠습니다.
편집 2: 컴퓨터를 몇 시간 동안 실행한 후 지금까지 모든 것이 잘 작동하는 것 같았습니다. 그러나 이전에 이 작업을 수행했지만 이번에는 무엇이 다른지 모르겠습니다.
편집 3: 컴퓨터가 다시 작동한 지 며칠 후에 작동이 btrfs balance멈추기 시작하여 전원을 꺼야 했습니다. 이제 나는 다시 원점으로 돌아왔습니다.
