rejecting I/O to offline device이 syslog 끝에 표시된 대로 이 오류가 무엇인지 확인하려고 합니다 .
아이디어:
- RAID-0 구성 문제(RAID-0에 2개의 4TB 디스크가 있고 이에 대한 경고가 표시됨)
- 가상 CD - 이 서버에는 CD가 없지만 설치를 위해 IPMI/KVM 도구를 통해 가상 CD를 연결했습니다. 지금은 첨부하면 안 되지만 관련 메시지를 몇 개 봤습니다.
위의 지침 외에도 네트워크 부팅 및 IPMI/KVM 콘솔을 통해 수행되는 ubuntu 12.04의 새로운 설치입니다.

고쳐 쓰다:
@jordanm 및 기타 - 정확합니다. 방금 이것이 CDROM 장치임을 확인했지만 이것은 서버의 IPMI를 통해 이전 KVM 세션에서 생성된 "가상 CD"입니다. 더 이상 존재하지 않습니다. 제거하는 방법을 아시나요? 아니면 액세스하려고 하지 마세요. 왜 거기에 있는지 모르겠습니다.
