Unable to make Cluster state to Green

anusha6 · January 20, 2016, 7:45am

Hello Team,
I am using two nodes in same host but am unable to see the cluster state as green,

Here is my response for cluster health
GET /_cluster/health?pretty=true

{
"cluster_name": "elasticsearch",
"status": "yellow",
"timed_out": false,
"number_of_nodes": 2,
"number_of_data_nodes": 2,
"active_primary_shards": 51,
"active_shards": 51,
"relocating_shards": 0,
"initializing_shards": 0,
"unassigned_shards": 51,
"number_of_pending_tasks": 0
}

Can anyone suggest me on this?????

You probably don't have enough disk space.
I think you can see it in logs...

It shows that your second node has been removed 2 minutes after it appeared.

Why did you stop it?
Why did you stop the first node as well?

When did you run the cluster health? In the mean time?

anusha6 · January 20, 2016, 9:35am

No that was like my last trail to make a two node cluster, normally I just pasted the logs that am getting when two nodes are connected..
that's it , am getting only those logs apart from the start and stop logs..

I have started two nodes and verified the cluster state got as yellow.....
Do I need to do anything more than this???

anusha6 · January 20, 2016, 9:41am

For you to know that how much space occupied by the indexes I pasted the indexes and the sizes they occupied,
So is that becaz of the more disk space occupied or due to any other reason???

And Yes I run the cluster health in the mean while..

dadoonet · January 20, 2016, 10:04am

Well the only time I saw my replicas not being allocated was when I was below 20% of available disk space.

I would:

start node 1 again
wait for yellow status
start node 2
call https://www.elastic.co/guide/en/elasticsearch/reference/current/cat-pending-tasks.html

anusha6 · January 20, 2016, 10:22am

I have my cluster settings as shown,
{ "persistent": {
"cluster": {
"routing": {
"allocation": {
"disable_allocation": "true"
}
}
},
"discovery": {
"zen": {
"publish_timeout": "30s"
}
},
"indices": {
"ttl": {
"interval": "15000"
}
}
},
"transient": {}
}

is it the cause????

anusha6 · January 20, 2016, 10:39am

Hello David,
I stopped two nodes and started them again, this time am getting few indexes as yellow and few are green

And am getting exception as

Why suddenly the behaviour changed from unassigned to assign of few shards and few got exceptions?????

dadoonet · January 20, 2016, 10:39am

Probably you did not install the phonetic plugin on the second node?

anusha6 · January 20, 2016, 10:54am

Thanks David, Installed plugin works fine all went to Green...
