I am running a single node of elasticsearch 2.2, and upon restarting the node all of the sudden all the shards got unassigned. This is the cluster health stats: > ``` > { > "cluster_name" : "elasticsearch", > "status" : "red", > "timed_out" : false, > "number_of_nodes" : 1, > "number_of_data_nodes" : 1, > "active_primary_shards" : 0, > "active_shards" : 0, > "relocating_shards" : 0, > "initializing_shards" : 4, > "unassigned_shards" : 108, > "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 > } > > ``` I've read about this problem happening on SOME of the shards on a multiple nodes cluster but I'm running a much simpler instance and this seems realy weird. ---

What do you have in logs? ---

I tried deleting the index logstash-de, and now this is the health status: > { > "cluster\_name" : "elasticsearch", > "status" : "red", > "timed\_out" : false, > "number\_of\_nodes" : 1, > "number\_of\_data\_nodes" : 1, > "active\_primary\_shards" : 50, > "active\_shards" : 50, > "relocating\_shards" : 0, > "initializing\_shards" : 0, > "unassigned\_shards" : 52, > "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" : 49.01960784313725 > } only the replica shards are unassigned ---

Replica shards will never assign when you have a single node, it defeats the purpose of having both primary and replica shards on the same node. ---

So why is the status still red? ---

Take a look at `_cat/shards`, you probably have an unassigned primary still. ---

I think that you should update your cluster settings by setting the replicas to 0 : ``` PUT /_settings { "index" : { "number_of_replicas" : 0 } } ``` This should solve the problem. make sure also that you did not disable automatic shard allocation in your yml cluster.routing.allocation.enable more here : [https://www.elastic.co/guide/en/elasticsearch/reference/current/shards-allocation.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/shards-allocation.html) ---

Thanks everyone for your answers! after disabling the replicas and deleting the kibana index it worked. Much appreciated! ---
