Hi Team,

We are running a POC on elastic search. We have three nodes

Node 1:  
node.master: true  
node.data: true  
node.ingest: true  
node.ml: false  
cluster.initial\_master\_nodes: ["ibs-dc-siem-1", "ibs-dc-siem-backup"]

Node 2:  
node.data: true  
node.master: true  
node.voting\_only: false  
node.ingest: true  
node.ml: false  
node.attr.box\_type: hot  
cluster.initial\_master\_nodes: ["ibs-dc-siem-1", "ibs-dc-siem-backup"]

Node 3: (Coordinating Node)  
node.data: false  
node.master: false  
node.ingest: false  
node.ml: false

If Node 1 Goes down , Kibana on all three goes down and Node 2 will not become master

If Node 2 goes down , Kibana will be available from Node 1, Node 2 and Node 3 all works fine.

Below is the error we get from kibana

`{"statusCode":500,"error":"Internal Server Error","message":"all shards failed: [node\_not\_connected\_exception] [ibs-dc-siem-1][10.181.10.176:9300] Node not connected"}

# Output When all three nodes are UP

Is there any more config to be done . Please help to resolve this

I would recommend you read [this](https://www.elastic.co/guide/en/elasticsearch/reference/7.8/high-availability-cluster-small-clusters.html). Just because you can make different nodes have different roles does not mean this is a good idea in a small cluster. I would recommend that you set up all nodes with default configuration and start from there. Your current configuration does not make much sense to me and I do not understand what you are trying to achieve or learn from it.

Hi Christian,

Thank you very much for pointing this document. I was able configure the nodes as per the doc and its worked perfectly. I am new to elasticsearch and we are doing a POC with small cluster with few clients pointed to it.

Thanks,  
Jijo John
