Migrating to Shared Blob Storage

Only available in Sonatype Nexus RepositoryTM Pro. Interested in a free trial? Start here.

Blob storage for highly available deployments must be in a shared network location accessible to all nodes in the deployment.

Before moving blob stores to a new location, update the path for the blob store in the Nexus Repository user interface. Nexus Repository requires the new location to be empty when changing an existing blob store location. Put your instance in read only mode during this operation to avoid corrupting the database during the move.

  1. Navigate to Settings → Blob Stores and select the blob store to move.

  2. Change the path of the blob store to point to the new location.

  3. Put Nexus Repository instance into read-only.

    Navigate to Settings → System → Nodes and select Enabled red-only mode.

  4. Move the blobs to the new shared location using one of the tools described above (e.g., rsync copy, vendor-provided tools, etc.)

  5. Unfreeze your Nexus Repository instance.

    Navigate to Settings → System → Nodes and select Disable read-only mode.
