Full disk on multiple-nodes deploymentedit
Health check
- Log in to the Elasticsearch Add-On for Heroku console.
-
From the Elasticsearch Service panel, click the Quick link icon corresponding to the deployment that you want to manage.
-
On your deployment page, scroll down to Instances and check if the disk allocation for any of your Elasticsearch instances is over 90%.
Possible cause
- The available storage is insufficient for the amount of ingested data.
Resolution
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.
Preventions
-
Increase the disk size.
-
On your deployment page, scroll down to Instances and identify the node attribute of the instances that are running out of disk space.
-
Use the node types identified at step 1 to find out the corresponding data tier.
-
From your deployment menu, go to the Edit page and increase the Size per zone for the data tiers identified at step 2.
-
- 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.
