Corrupted component database (Nexus RM on Openshift)

Hi all, yesterday my Nexus Repository Manager running as container on Openshift 3.11, after working well for 2 years, suddenly crashed.

Image used is

registry.connect.redhat.com/sonatype/nexus-repository-manager:3.28.1-ubi-1

After reading many articles on forums, communities, etc, I tried to start a debug pod, delete .wal files under /nexus-data/db/config and /nexus-data/db/security and then repair these two databases.

I followed these procedures:

• Unable to start Nexus repository on CentOS 7 running on AWS
• Fix Sonatype Nexus OrientDB · GitHub

Config and security databases was fixed, but if I try to reach the component db from the orient db console with the following command:

java -jar  /opt/sonatype/nexus/lib/support/nexus-orient-console.jar

connect plocal:/nexus-data/db/component/ admin admin

I obtain the following error, that is the same I can see in the pod logs:

Disconnecting from the database [null]…OK

It seems like no more database component is present (file corruption??)

Unfortunately I do not have a backup/export for this database.

Any suggestion? Is it possibile create an empty DB and start like a fresh installation only for this database, maintaining the other 2? Or recreate the missing “configuration file for storage component” which is reported in the logs?

Thanks and regards,
