List Unassigned shards by index by node

Elastic Stack Elasticsearch
#1

Hi All,

I have looked through to find out any api available to list down the
unassigned shards.
Currently the cluster health api only list the number of unassigned shards.

{
"cluster_name" : "elasticsearch",
"status" : "red",
"timed_out" : false,
"number_of_nodes" : 5,
"number_of_data_nodes" : 5,
"active_primary_shards" : 36,
"active_shards" : 36,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 3
}

But my requirement is to list down the unassigned shard along with the index
name and node that they belong to.

I have called the index status and segment api;

curl -XGET 'http://localhost:9200/_status' -- all shards have "state"
"STARTED"
curl -XGET 'http://localhost:9200/_segments'

but I don't get which shards are faling.

Any help would be greatly appreciated.

Thanks
Amit

Look at the results of
curl -XGET http://localhost:9200/_cluster/state?pretty=true

  • you'll probably want to pipe that into less. Search for the string
    UNASSIGNED.

Thanks Israel,

That helped , I called all other api except for cluster state api.

Now when I know the unassigned shards, I am trying to allocated them to a
node.

curl -XPOST '10.62.145.101:9200/_cluster/reroute' -d '{"commands" :
[{"allocate" : "index"
:"51c33c8d9a5cb0e4a498e94c51c438855555b0e40a09137a1","shard" : 3,
"node" : "fJxYr_ZMQyagiA2ilKVLYA"}}]}'

But when I call the cluster state api , I still get the same result.
I mean the shard did not got assigned to a node.

Thanks
Amit
