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.

    1. On your deployment page, scroll down to Instances and identify the node attribute of the instances that are running out of disk space.

    2. Use the node types identified at step 1 to find out the corresponding data tier.

    3. From your deployment menu, go to the Edit page and increase the Size per zone for the data tiers identified at step 2.

      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.
  • Enable data tiers to move older data that you don’t query often to more cost-effective storage.
