Fix master nodes out of disk

edit

Elasticsearch is using master nodes to coordinate the cluster. If the master or any master eligible nodes are running out of space, you need to ensure that they have enough disk space to function. If the health API reports that your master node is out of space you need to increase the disk capacity of your master nodes.

  1. Log in to the Elastic Cloud console.
  2. On the Elasticsearch Service panel, click the gear under the Manage deployment column that corresponds to the name of your deployment.
  3. Go to Actions > Edit deployment and then go to the Master instances section:

    Increase disk capacity of master nodes
  4. Choose a larger than the pre-selected capacity configuration from the drop-down menu and click save. Wait for the plan to be applied and the problem should be resolved.
