any update?

I get this:

any update on this @bigmyx ?

In case anyone else encounters this issue, try running the $ docker-compose exec nexus java -jar ./lib/support/nexus-orient-console.jar command with the root user specified:

$ docker-compose exec -u root nexus java -jar ./lib/support/nexus-orient-console.jar

After running the commands from the original snippet, make sure to restore ownership of all database files back to the nexus user and nexus group, as the modified files will now belong to the root user!

If you are getting bigmyx's error:

You can truncate the record as described here: https://mariosk.wordpress.com/2019/09/07/how-a-nexus-repository-manager-corruption-led-to-a-mini-odyssey/
After i fixed all the dups to fix index: asset_bucket_component_name_idx i encountered a lot more appeared in the browse_node_repository_name_parent_path_name_idx index, after fixing a couple of dozes manually i dropped the class browse_node as mentioned here: https://issues.sonatype.org/browse/NEXUS-16419 this should only have affect on the webui and after restart you the indexes are repopulated.

Another note about this: With nexus OSS 3.15.1, when it ran out of disk space, it created WAL files with zero file size. These caused orientdb to croak with null pointer exceptions on startup. I just had to remove the zero size files, and then the above commands worked perfectly.

Many thanks
