All my nodes in cluster except one went down. If I run \_cat/nodes in active node , its showing master\_not\_discovered exception. Im not even able to take backup. Backup fails with same error. Can I recover the data somehow? ---

Ok, then you're likely out of luck, see [the docs here](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery-quorums.html); > To be sure that the cluster remains available you **must not stop half or more of the nodes in the voting configuration at the same time**. ---

> [@warkolm](#): > > To be sure that the cluster remains available you ok thanks. In my case, I have three nodes cluster, two nodes went down . Im trying to create a new cluster with two new nodes and one active node. So it seems like I can create a cluster with one old node and two new nodes, but I will be losing data in my old node. I cant recover it. Correct? ---
