안녕하십니까?? 웹서버 한대를 운용중이고
최근에 yum update를 통해서 업데이트를 해줬는데 다음과 같은 에러 메시지를 확인하였습니다.

아마 하드의 배드섹터가 발견되었다는 문제 같은데
배드섹터가 얼마나 치명적인지에 대한 감이 없어서 질문드립니다.
결과적으로 하드 교체가 답이겠지만 사용하는데 별 문제가 없다면 그냥 그대로 사용하면 안되는지 궁금해서 질문드립니다.
하드는 중고로 있는것을 사용해서 오래된 것입니다.
감사합니다.
--수정--
smartctl --all /dev/sda 의 결과중 일부입니다. 상태가 어떤 상태인지 확인해 주시면 감사하겠습니다.
