# Fix data nodes out of disk
Elasticsearch is using data nodes to distribute your data inside the cluster. If one or more of these nodes are running out of space, Elasticsearch takes action to redistribute your data within the nodes so all nodes have enough available disk space. If Elasticsearch cannot facilitate enough available space in a node, then you will need to intervene in one of two ways:
1. [Increase the disk capacity of your cluster](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/troubleshoot/elasticsearch/increase-capacity-data-node)
2. [Reduce the disk usage by decreasing your data volume](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/troubleshoot/elasticsearch/decrease-disk-usage-data-node)
