    Full disk on single-node deployment

Possible cause

  • The available storage is insufficient for the amount of ingested data.


If your Elasticsearch cluster is unhealthy and reports a status of red, you can only delete unused data or reach out to support@elastic.co for help. If your Elasticsearch cluster reports a status of yellow or green, you might still take the following preventive steps.


  • Increase the disk size on your Hot and Content tier.

    From your deployment menu, go to the Edit page and increase the Size per zone for your Hot data and Content tiers.

    Increase size per zone
  • Enable autoscaling to grow your cluster automatically when it runs out of space.
  • Configure (ILM) policies to automatically delete unused data.
  • Add nodes to your Elasticsearch cluster and enable data tiers to move older data that you don’t query often to more cost-effective storage.
