curl '[http://localhost:9200/datavasanth-21-9-2017/\_segments?pretty=true](http://localhost:9200/datavasanth-21-9-2017/_segments?pretty=true)'  
{  
"\_shards" : {  
"total" : 10,  
"successful" : 0,  
"failed" : 0  
},  
"indices" : { }  
}  
does it mean the data has been marked for delete but index exist?

The above index datavasanth-21-9-2017 is under unassigned shard.

this means there are 10 shards but non of them is allocated so we can't tell how many segments are there.
