I installed elastic search on 2 servers with different ips. and they are found in the cluster one master and one data node and their names are master and data. when I was trying to run kibana on the master it kept hanging on missing shards so I ran cluster health and got
"cluster\_name" : "elastic",
"status" : "red",
"timed\_out" : false,
"number\_of\_nodes" : 2,
"number\_of\_data\_nodes" : 1,
"active\_primary\_shards" : 0,
"active\_shards" : 0,
"relocating\_shards" : 0,
"initializing\_shards" : 0,
"unassigned\_shards" : 1,
"delayed\_unassigned\_shards" : 0,
"number\_of\_pending\_tasks" : 0,
"number\_of\_in\_flight\_fetch" : 0,
"task\_max\_waiting\_in\_queue\_millis" : 0,
"active\_shards\_percent\_as\_number" : 0.0
}
after that I used curl -X GET "localhost:9200/\_cluster/allocation/explain'
{
"index" : ".kibana\_1",
"shard" : 0,
"primary" : true,
"current\_state" : "unassigned",
"unassigned\_info" : {
"reason" : "CLUSTER\_RECOVERED",
"at" : "2019-01-23T10:27:59.262Z",
"last\_allocation\_status" : "no\_valid\_shard\_copy"
},
"can\_allocate" : "no\_valid\_shard\_copy",
"allocate\_explanation" : "cannot allocate because a previous copy of the primary shard existed but can no longer be found on the nodes in the cluster",
"node\_allocation\_decisions" : [
{
"node\_id" : "seAK3Tv6ScKi408Y5-QoNA",
"node\_name" : "data",
"transport\_address" : "172.18.25.35:9300",
"node\_attributes" : {
"ml.machine\_memory" : "16657784832",
"ml.max\_open\_jobs" : "20",
"xpack.installed" : "true",
"ml.enabled" : "true"
},
"node\_decision" : "no",
"store" : {
"found" : false
}
}
]
}
how can I fix this

Do you have dashboards that you have created that you want to keep?

What does the output from the `_cat/indices` API show?

If you delete that index you should recover.
Also you really want to have an odd number of nodes, see [https://www.elastic.co/guide/en/elasticsearch/guide/2.x/important-configuration-changes.html#\_minimum\_master\_nodes](https://www.elastic.co/guide/en/elasticsearch/guide/2.x/important-configuration-changes.html#_minimum_master_nodes) for more.
