Hi
I have two nodes(xnode1, xnode2) cluster on elasticsearch 7.13. I made cluster succesfully, it showing 2 nodes in cluster.
For testing i stop xnode2, it showing 1 node cluster. but when stop xnode1 , then try curl with xnode2 it showing : master\_not\_discovered\_exception.
When i stooping 2nd node xnode2 getting
```auto
[2021-06-15T07:10:31,830][WARN][o.e.c.c.ClusterFormationFailureHelper] [xnode1] master not discovered or elected yet, an election requires a node with id [D4NWZ2baTf2hdUF6VgZ65A], have discovered [{xnode2}{Q8_O0deGQomb2mGM5KN4Ew}{3cAb9kpeS1SpCGOlN17MFQ}{192.168.10.2}{192.168.10.2:9300}{cdfhilmrstw}] which is not a quorum; discovery will continue using [192.168.10.1:9300] from hosts providers and [{vodaxsimnode1}{D4NWZ2baTf2hdUF6VgZ65A}{JdGeacDuT6Cvcl0poLgDJQ}{192.168.10.1}{192.168.10.1:9300}{cdfhilmrstw}, {xnode2}{Q8_O0deGQomb2mGM5KN4Ew}{3cAb9kpeS1SpCGOlN17MFQ}{192.168.10.22}{192.168.10.2:9300}{cdfhilmrstw}] from last-known cluster state; node term 3, last-accepted version 49 in term 3
Please help me, i want make cluster with two nodes. Thanks
Configuration on xnode1 :
cluster.name: mucluster
node.name: xnode1

cluster.initial_master_nodes: ["192.168.10.1","192.168.10.2"]
#cluster.initial_master_nodes: ["xnode1","xnode2"]
Configuration on xnode2 :
cluster.name: mucluster
node.name: xnode2

This older [post](https://discuss.elastic.co/t/master-not-discovered-exception-for-two-node-cluster/243452/3) provides more details.
Also, this part of [docs](https://www.elastic.co/guide/en/elasticsearch/reference/7.13/add-elasticsearch-nodes.html#modules-discovery-removing-nodes) may also be of benefit to understand the situation when you are down to 2 master-eligible nodes and one is removed.

A 2 node cluster can not be highly available and continue operating fully if one node goes down. Please read [this section in the docs](https://www.elastic.co/guide/en/elasticsearch/reference/7.13/high-availability-cluster-small-clusters.html) for further details.

In order to elect a master a strict majority of master eligible nodes need to be available. The majority of 2 is 2 which means a 2-node cluster can not elect a master as soon as one node is down. If you add a third node with the same main configuration you have 3 master eligible nodes in the cluster. The majority of 3 is 2 which means that even if 1 node goes offline the remaining 2 can elect a master and continue operating safely.

okay, but i my case only first node become master, even i stopped 2nd node first working.
[If 2nd node stopped then in cluster showing 1 node] , but when stooping 1st one this one become issue, why i can not make 2nd node master, already given in configuration.

I am not sure I understand. It doesn't matter which node is elected master when both nodes are available.
