내 어레이의 하드 드라이브 중 하나에 문제가 있는 것 같아 문제를 해결하려고 합니다.
Faulty Spare라고 표시되고 재부팅 후에는 제거되었다고 표시됩니다.

smartctl -a /dev/sdb2를 실행했는데 통과했다고 나오네요. 하지만 작업 중인 드라이브에 비해 RAW_VALUE 숫자가 정말 높았습니다.

실제로는 아직 자가 테스트를 성공적으로 수행하지 못한 것 같습니다.

smartctl -t long /dev/sdb를 실행해 보세요.

드라이브에 오류가 발생했지만 모든 오류 관련 숫자가 오류 임계값보다 높기 때문에 "SMART 오류"를 트리거할 만큼 충분히 실패하지는 않았습니다. RAID 실패 이벤트의 가장 가능성 있는 원인은 수정 불가능한 읽기 오류(SMART 속성 187)입니다.
