Administrator Operations

This section documents operations required by administrators to maintain an Ozone system in a production environment.

📄️ Starting and Stopping Ozone Services

Ozone services (Ozone Manager, Storage Container Manager, Datanode, Recon, S3 Gateway) are typically managed using the ozone command-line interface (CLI) tool provided with the Ozone distribution.

📄️ Upgrading and Downgrading Ozone

Ozone supports a non-rolling upgrade process, which requires stopping the cluster, replacing software binaries, and restarting the components. It also includes a finalization step that commits the cluster to the new version and enables new features, after which downgrading is no longer possible.
