I am trying to set number\_of\_replicas to 0 in all indices with:
PUT /\_settings
{
"index" : {
"number\_of\_replicas":0
}
}
but after that it doesnt change any index number\_of\_replicas to 0 and still are 1
get \_settings
....
".monitoring-alerts-6": {
"settings": {
"index": {
"codec": "best\_compression",
"number\_of\_shards": "1",

I wonder if you need to do it that way:
```auto
PUT /*/_settings
{
"index" : {
"number_of_replicas":0
}
}
```
Or one by one...

It doesnt work I tried both \* or one by one and i cant change any . index like .kibana, .watches, .security-6. .monitoritng,etc .... any idea?
PUT /.kibana/\_settings
{
"index" : {
"number\_of\_replicas":0
}
}
get /.kibana/\_settings
{
".kibana": {
"settings": {
"index": {
"number\_of\_shards": "1",
"auto\_expand\_replicas": "0-1",
"provided\_name": ".kibana",
"creation\_date": "1532333518766",
"number\_of\_replicas": "1",

}
}

I agree it should not make a difference, but I would try using the API and see if you get any response back other than "acknowleged":true
curl -XPUT -H 'Content-Type: application/json' 'localhost:9200/.monitoring-kibana-6-2018.07.25/\_settings' -d '{ "number\_of\_replicas" : 0 } }'

I am using elastic hosted cloud instance so i cant ssh to run that curl command but i run from another computer and it still doesnt change anything.

So in cloud you can have a Kibana instance deployed. Did you do that?
If so, just open Kibana and the developer console.
Then you can paste the curl command in.
How did you run previously the commands?

yes i have kibana and i run the commands previously but it doesnt change number of replicas for .\* indices just for regular indices.
I was replying to michaelm14 that was asking to run curl commands on ssh cand i cant do that on cloud.
But i already tried in kibana in dev console to run:
PUT /.kibana/\_settings
{
"index" : {
"number\_of\_replicas":0
}
}

What is the output of:
```auto
GET _cat/nodes?v
```

So I guess this is caused by `"auto_expand_replicas": "0-1"` which basically means "replicate if you can"...

and is possible to modify that settings to alow set number of replicas to 0?

I don't know. Sounds like a new setting I never used.
May be:
```auto
PUT /.kibana/_settings
{
"index" : {
"number_of_replicas":0,
"auto_expand_replicas": false
}
}
```
