how to assign shards which are actual unassigned? - elasticsearch

Question

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:
red open logstash-2015.11.08 5 0 47256 668 50.5mb 50.5mb
red open logstash-2015.11.09 5 0 46540 1205 50.4mb 50.4mb
red open logstash-2015.11.06 5 0 65645 579 69.2mb 69.2mb

red open logstash-2016.04.13 5 0 95120 279 107.2mb 107.2mb
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

Answer 2

if shards are stuck in unallocated they can be manually allocated. For example:
curl -XPOST 'localhost:9200/_cluster/reroute' -d '{
"commands": [{
"allocate": {
"index": "logstash-2015.11.07",
"shard": 5,
"node": "Frederick Slade",
"allow_primary": 1
}
}]
}'
See the Cluster Reroute documentation, including warnings on the use of allow_primary.
