title: Elasticsearch no disk space available
body: <p>I have a 3 nodes Elasticsearch cluster that exhausted the disk space in each node. Each node is an EC2 instance. The cluster is now completely irresponsive.</p>
  
  <p>What solutions do I have to free up space?</p>
  
  <p>Would adding a node in cluster free up space in the other node because now the cluster will re-distribute the information over the other nodes?</p>
  
  <p>Or is my only solution but definitely not the preferred ones is to create a larger cluster on the side and migrate over the data from the first cluster?</p>
  
  <p>Any other ideas/solutions is more than welcome.</p>
  
  <p>The cluster configuration on each node(elasticsearch.yml) looks as follows:</p>
  
  <pre><code>cluster.name: AutoSearchCluster
  node.name: i-asd4352
  plugin.mandatory: cloud-aws
  discovery.zen.ping.multicast.enabled: false
  discovery.type: ec2
  cloud.aws.region: us-west-2
  discovery.ec2.groups: prod-group
  gateway.recover_after_nodes: 2
  gateway.expected_nodes: 3
  gateway.recover_after_time: 5m
  indices.fielddata.cache.size: 40%
  </code></pre>
  
  <p>Thx in advance.</p>
