After losing the masters there's no guarantees that your data will come back intact, but you can try the [`elasticsearch-node` tool](https://www.elastic.co/guide/en/elasticsearch/reference/current/node-tool.html), particularly [`elasticsearch-node detach-cluster`](https://www.elastic.co/guide/en/elasticsearch/reference/current/node-tool.html#node-tool-detach-cluster). Please read the instructions carefully and understand the risks before proceeding.

For future reference, it's vitally important to use persistent volumes for the master-eligible nodes in the cluster, as well as for the data nodes.
