Error: rpmdb open failed

[santosh]

Just sharing one RPM database corrupted issue on the Centos server.

I was trying to update the system packages on the server, but I was getting the below error.

[root@server ~]# yum update
rpmdb: Thread/process 140135/140671782139648 failed: Thread died in Berkeley DB library
error: db3 error(-30974) from dbenv->failchk: DB_RUNRECOVERY: Fatal error, run database recovery
error: cannot open Packages index using db3 -  (-30974)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:

Error: rpmdb open failed

I suspected an issue with the yum cache, so I tried to clean it but it did not work.

[root@server ~]# yum clean
rpmdb: Thread/process 140135/140671782139648 failed: Thread died in Berkeley DB library
error: db3 error(-30974) from dbenv->failchk: DB_RUNRECOVERY: Fatal error, run database recovery
error: cannot open Packages index using db3 -  (-30974)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:

Error: rpmdb open failed

Then, I tried to rebuild the RPM database but error was still the same:

[root@server ~]# rpm --rebuilddb
rpmdb: Thread/process 140135/140671782139648 failed: Thread died in Berkeley DB library
error: db3 error(-30974) from dbenv->failchk: DB_RUNRECOVERY: Fatal error, run database recovery
error: cannot open Packages index using db3 -  (-30974)

At last, I found the actual issue. The rpm db was corrupted so I repaired it using the below steps:

[root@server ~]# ls /var/lib/rpm
Basenames     __db.001  __db.003  Dirnames     Group       Name          Packages     Provideversion  Requirename     Sha1header  Triggername
Conflictname  __db.002  __db.004  Filedigests  Installtid  Obsoletename  Providename  Pubkeys         Requireversion  Sigmd5

[root@server ~]# rm -f /var/lib/rpm/__*
[root@server ~]# rpm --rebuilddb
[root@server ~]#

It works!!.
