Another message will be sent in 24 hours if the problem persists.
Syslog에는 추가 정보가 표시되지 않습니다.
확장된 스마트 테스트를 수행한 다음 테스트 결과에 지정된 섹터에 기록하여 드라이브가 이를 불량 섹터로 표시하고 재할당하도록 해야 한다는 내용을 다른 곳에서 읽었습니다.
나는 긴 테스트를 실행했습니다.
sudo smartctl -t long /dev/sda1
그러나 sudo smartctl -a /dev/sda1의 출력에는 테스트가 오류 없이 완료되었다고 나와 있습니까?

정말 문제가 있는 걸까요? 그렇다면 제대로 진단하는 방법은 무엇인가요?
답변1
단 1개의 보류 섹터만 드라이브에 문제가 되지 않습니다. 눈에 띄게 증가할 때까지 무시하세요.
다음 지침을 사용하여 문제를 해결할 수 있지만(먼저 데이터를 백업하세요!):https://github.com/smartmontools/smartmontools/blob/master/www/BadBlockHowTo.txt
또한 드라이브 SMART 보고서를 다른 보고서와 비교할 수 있습니다.이 SMART 보고서 저장소.
답변2
가장 큰 질문은 해당 섹터에 관심 있는 데이터가 있는지 여부입니다. 데이터 파일을 읽고 누락된 것이 있는지 확인하십시오.
어떤 경우에도 이 오류 메시지가 반복되는 것을 방지하려면 드라이브가 이를 무시할 수 있도록 데이터를 덮어써야 합니다. 다른 용도로 사용되지 않는 블록을 자르는 것도 효과가 있습니다. 이 문제를 해결하려면 파일 시스템에서 fstrim을 수행해 보세요.
SMART 장기 테스트는 미디어에 대해 무작위 테스트를 수행하며 완전한 테스트가 아니므로 오류가 있어도 성공할 수 있으며 특히 제조업체가 보류 중인 단일 오류가 발생하는 것을 원하지 않기 때문에 복구 가능한 오류인 경우 더욱 그렇습니다. 드라이브를 RMA하게 됩니다.
