fsck 이상증상?

안녕하세요.

고객의 서버를 관리중에 있는데 /home 이 2TB 디스크에 /dev/sdb1 로 마운트되어 있고 3TB 백업하드에 /dev/sdc1 로 마운트

되어 있는 상태입니다. 문제는 /home 의 자료를 rsync 로 /backup (/dev/sdc1) 에 동기화하는 과정에서 자꾸 서버가 죽는

현상이 반복되어 fsck -n /dev/sdb1 (sdb1 은 마운트되어 있는상태) 를 실행하면 아래와 같이

fsck from util-linux-ng 2.17.2
e2fsck 1.41.12 (17-May-2010)
Warning! /dev/sdb1 is mounted.
Warning: skipping journal recovery because doing a read-only filesystem check.
/dev/sdb1 contains a file system with errors, check forced.

파일시스템에 에러가 발생하였다고 나와서 sdb1 을 새벽시간대에 umount 하고 fsck -y /dev/sdb1 명령어를 실행하면

pass1~pass5 까지 체크는 되나 위와 같은 메시지가 발견되지 않고 단순히 체크만 하고 종료되버립니다.

이후 다시 sdb1을 마운트 하고 fsck -n /dev/sdb1 을 실행하면 파일시스템 에러가 그대로 존재하는데

이런경우 해당증상을 fix 하는 방법에는 어떠한게 있을지 조언 부탁드립니다.

참고로 혹시나 하여 badblocks -v /dev/sdb1 명령어를 약 4시간가량 실행한 후 확인해보았으나 배드블록 발견은 없는 상황입니다.

감사합니다.
