답변1
"잘못된 인수"는 다음에서 올 수 있습니다 perror.오류 번호 EINVAL 보고설정을 통해 unlink.
~에 따르면매뉴얼 페이지unlinkat, EINVAL 은 가 아닌 로만 나타날 수 있으며 unlinktruss 출력에는 unlink호출이 표시되므로 이 시나리오는 불가능해 보입니다. 그러나 우리는 여기 있습니다.
내가 좀 찾았어기타 보고서기본 파일 시스템이 파일 이름의 인코딩을 처리할 수 없는 경우 유틸리티는 "잘못된 인수"를 보고합니다.
파일 이름이 일반 ASCII 문자로 나타나므로 이는 문제가 되지 않을 수 있지만 여기서는 EINVAL이 파일 시스템 특정 코드에 의해 호출되는 것으로 의심되므로 unlink사용 중인 파일 시스템에 따라 다릅니다. Isilon NAS 클러스터에서는 다음과 같을 수 있습니다.통합 파일 시스템, 이상한 위치(예: tmpfs 또는 FUSE 마운트)에 있거나 이동식 미디어에 있는 경우는 제외됩니다.
이 경우 실제 Isilon 엔지니어에게 코드를 조사하여 연결 해제 시 EINVAL이 발생하는 원인이 무엇인지 알아내도록 할 수 있습니다.
