how to assign shards which are actual unassigned?

Problem: I've started five elasticsearch nodes, but only 66,84 % of the Data is in kibana available. When I check the cluster health with localhost:9200/_cluster/health?pretty=true I've got the following informations: { "cluster_name" : "A2A", "status" : "red", "timed_out" : false, "number_of_nodes" : 5, "number_of_data_nodes" : 4, "active_primary_shards" : 612, "active_shards" : 613, "relocating_shards" : 0, "initializing_shards" : 0, "unassigned_shards" : 304, "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" : 66.8484187568157 }

And also all my indices are red, except of the kibana index.

Small Part:

I've tried to fix the problem with curl -XPUT 'localhost:9200/_settings' -d ' {"index.routing.allocation.disable_allocation": false}' but it doesn't work!

So has anyone of you some ideas how to assign my shards?

And when you need some other infos please ask and I will try to offer you the data:

You could also try restarting elasticsearch first: service elasticsearch restart.

Otherwise, just try reallocating the shards manually (as your indices have 5 shards, run the command with the shard flag 0, 1, 2, .. 5):

curl -XPOST -d '{ "commands" : [ {
  "allocate" : {
       "index" : "logstash-2015.11.08", 
       "shard" : 0, 
       "node" : "SOME_NODE_HERE",
       "allow_primary":true 
     } 
  } ] }' http://localhost:9200/_cluster/reroute?pretty`

You can check the nodes with unassigned shards using: curl -s localhost:9200/_cat/shards | grep UNASS
