충돌 후 손상된 파일 시스템이 있습니다 xfs_repair -n. 페이지에 명시된 대로 xfs_repair man손상 xfs_repair -n이 감지되면 존재하고 상태 1을 반환합니다. 그래서 xfs_repair파일 시스템에서 실행한 다음 xfs_repair -n다시 실행합니다. 종료 상태는 여전히 1입니다.
~에 따르면Linux 관리를 위한 XFS 4장xfs_repair모든 문제를 해결하려면 최대 3번의 실행이 필요할 수 있습니다 . 지금까지 이 작업을 4번 실행했지만 종료 상태는 xfs_repair -n여전히 1입니다. 파일시스템이 마운트되어 있어서 원칙적으로는 데이터에 접근이 가능하지만, 실제로 무엇이 손상되었는지, 어떻게 해결할 수 있는지 알아낼 수 있는 다른 옵션이 있는지 궁금합니다.

답변1
문제는 다음과 같습니다.Ext4 fs를 사용하는 또 다른 것이 있습니다, xfstools용 32비트 바이너리가 포함된 복구 CD로 인해 발생했습니다(커널 자체가 64비트임에도 불구하고).
그래서 결국 루트 파티션을 마운트하고(문제 없음) xfs_repair -n거기에서 실행하기 위해 루트 파티션으로 이동했습니다. 예상대로 0이 반환되었습니다.
