I'm running Elastic 7.13.3 in a 3 Node Cluster Environment on Windows at a Customer where within 3-4 hours two SSD's failed to operate and from 3 Nodes only one Node is still up an running although i can not access this Node since it's saying that no Master Node can be elected - this is true indeed since 2 Nodes are off and i was thinking that since i've got 2 replicas of every shard this should be easy - even if 2 nodes are failing, one Node is still operable - so my question ist, how to get this Node running (i tried to change the .yml file, and even to start another node with no data but no success) - is there a way to start a single node and have a least this one up and running? I was wandering, wouldn't it be better to have 3 single Clusters with 1 Node and distribute the Data between these Nodes so there wouldn't be such a uncomfortable situation ...? Thanks Andy ---

You probably need to look at the [elasticsearch-node](https://www.elastic.co/guide/en/elasticsearch/reference/7.17/node-tool.html) utility. Have not had to use it myself though so will not be much help. ---

Thanks Christian, i'm really worried about the data since i can start the node but it is not accessible since it's always saying no master node could be elected although i've reduced the cluster to node in the .yml file - there might be something in the data which could lead to this issue? i don't know but i might do something wrong! ---

If a majority of master eligible nodes have been lost there is no dafe way to get the cluster back up. The docs I linked to recommends setting up a new cluster and restore from a snapshot. If this is not possible you may need to use the utility I linked to perform [an unsafe bootstrap](https://www.elastic.co/guide/en/elasticsearch/reference/8.2/node-tool.html#node-tool-unsafe-bootstrap), which could lead to data loss. I have never had to do this so will leave it to others with more practical experience in this area to comment/provide feedback. ---
