Buffer I/O error on device.. 이란 에러에 대하여 아시나요?
글쓴이: azena / 작성시간: 수, 2010/04/28 - 1:12오전
부팅하는데 같은 에러가 계속 발생하고 있습니다.
실제 사용하는데는 큰 문제는 없는거 같은데요.
부팅할 때 이런 메시지가 계속 뜨니까 나중에 문제가 생기지 않을까 하는 노파심이 생기는군요.
혹시 이런 문제 발생 원인과 해결 방법 아시는 분은 답변 부탁드립니다.

시스템 사양입니다.
배포판 CentOS 5.4 64bit
커널 2.6.18-164.el5
시스템 HP 프로리언트 DL360-G6 쿼드, ICH9
스토리지 컨트롤러 HP 스마트 어레이 B110i SATA RAID 컨트롤러 (RAID 0/1/0+1)
현재 RAID 1로 사용하고 있습니다.
CentOS에는 B110i 드라이버가 기본 지원되지 않아 RHEL용 스토리지 드라이버를 설치하였습니다.
밑의 sda 접근
밑의 sda 접근 에러메시지 보니까 하드 크기를 넘어서는 부분을 액세스하고 있군요.
드라이버 등등... 어디선가 하드 size를 잘못 잡고 있어서 생기는 것으로 보이네요. 드라이버가 제대로 잡아낸다면 하드 크기를 벗어나는 섹터 접근을 하지 않으니까요.
