리눅스 하드디스크 점검 유틸리티



스마트모니터툴로 운영중인 하드디스크 상태를 확인 할 수 있습니다.


운영중인 서버의 두번째 디스크인데 상태가 안좋아서 사용하지 않고 있는 하드디스크입니다.


# smartctl -a /dev/sdb 로 상태를 체크했는데 문제로 보이는 항목입니다.


Raw_Read_Error_Rate <= 디스크에서 읽기 실패, 소프트웨어적인 오류

Reallocated_Sector_Ct <= 섹터에 문제가 있어 다른영역으로 치환된 횟수


위 처럼 오류가 있다면 배드섹터를 체크해 보세요~


# badblocks -wsv /dev/sdb

Checking for bad blocks in read-write mode

From block 0 to 976762583

Testing with pattern 0xaa:   0.10% done, 2:38 elapsed


-w 옵션은 쓰기모드이므로 기존 데이터가 지워집니다.

비파괴 검사를 하려면 -n 을 주세요.


아래는 smartctl 전체 내용입니다.
