rpmdb: unable to join the environment
How time flies? It only seemed like yesterday that I installed CentOS 5.4 at a customer site. This week I needed to update rsync
from 2.6.8 to what ever the latest version is. So I typed:
yum update rsync
and got the following message.
Loaded plugins: fastestmirror
rpmdb: unable to join the environment
error: db4 error(11) from dbenv->open: Resource temporarily unavailable
error: cannot open Packages index using db3 - Resource temporarily unavailable (11)
error: cannot open Packages database in /var/lib/rpm
Traceback (most recent call last):

idx = ts.dbMatch('provides', distroverpkg)
TypeError: rpmdb open failed
I also tried:
rpm -qa
which resulted in:
rpmdb: unable to join the environment
error: db4 error(11) from dbenv->open: Resource temporarily unavailable
error: cannot open Packages index using db3 - Resource temporarily unavailable (11)
error: cannot open Packages database in /var/lib/rpm
Even though the message says Resource temporarily unavailable, it was in fact always unavailable! Hunted around and found this article which helped a lot.
The problem is caused by an empty database index file in the RPM repository, probably caused by corruption. In my case it was because most of the index files were missing.
$ ls -l /var/lib/rpm

So all I needed to do was remove all the index files and rebuild them.
rm -rf /var/lib/rpm/__db*
rpm -rebuilddb
The RPM repository now looks like:

I re-issued the update command:
yum update rsync
and it successfully installed rsync 3.0.6-4.el5_7.1
.
Interestingly, CentOS 5.4 has been deprecated and so this version of rsync
was for CentOS 5.7, but it didn't need to install any dependencies.
