sudo mkdir -p /data/nexus-libraries sudo chown -R nexus:nexus /data/nexus-libraries # Ensure correct user permissions sudo chmod 750 /data/nexus-libraries Copying preserves the original as a fallback. For large libraries (hundreds of GB), use rsync to maintain symlinks and permissions.
sudo rsync -avh --progress /opt/sonatype-work/nexus3/blobs/ /data/nexus-libraries/ Wait for completion. Verify sizes: du -sh /opt/sonatype-work/nexus3/blobs/ vs du -sh /data/nexus-libraries/ To permanently update the nexus library location, you must edit two specific files. Do not change the nexus-work directory unless you are moving the entire instance. update nexus library location
(Usually in /opt/nexus/etc/ ) Locate the line starting with karaf.data . This dictates the work directory. This dictates the work directory
