.Introduction of `diskprediction` module The {product} `diskprediction` module gathers metrics to predict disk failures before they happen. The module has two modes, cloud and local. With this release, only the local mode is supported. The local mode does not require any external server for data analysis. It uses an internal predictor module for disk prediction service, and then returns the disk prediction result to the Ceph system. To enable the `diskprediction` module: ---- ceph mgr module enable diskprediction_local ---- To set the prediction mode: ---- ceph config set global device_failure_prediction_mode local ---- To disable the `diskprediction` module: ---- ceph config set global device_failure_prediction_mode none ----
