Error: rpmdb open failed떄 복구 시나리오

rpm DB가 깨어진 상태와 복구가 필요한 테스트가 필요하여 시나리오를 구성 해보았다.

1.먼저 간단히 rpm DB를 아래와 같이 깨어진 상태를 만든다. 이미 깨어진 상태라면 이 과정은 생략 한다.

# cd /var/lib/rpm
# cat /dev/null > __db.001
# cat /dev/null > __db.002
# cat /dev/null > __db.003 

2.이후 아래와 같이 yum check-update 명령을 사용 하면 Error: rpmdb open failed 에러 메세지가 확인이 가능하다.

# yum check-update
error: db5 error(11) from dbenv->open: Resource temporarily unavailable
error: cannot open Packages index using db5 - Resource temporarily unavailable (11)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:
Error: rpmdb open failed

3.rpm –rebuilddb 명령을사용하여 복구를 시도 한다. -vv 옵션을 통해 복구 과정을 확인 가능하다.

# rpm --rebuilddb -vv

4.최종적으로yum clean all을 한후, yum check-update 를 확인하여 복구된 rpm DB를 확인한다.

# yum clean all
# yum check-update
