Hi All,

I've tried to change the index settings (templates too) for the below special (+X-Pack) indexes from 1 primary 0 replica to 1 primary 2 replicas but overnight the settings have been changed back.

Let's say for .kibana, I would like to have at least one replica in case it gets corrupted or the node with it gets down in a cluster. In this case all users cannot use Kibana as .kibana index is unreachable.

.kibana  
.logstash  
.ml-notifications  
.ml-state  
.monitoring-es-6-  
.monitoring-logstash-6-\*  
.security-6  
.triggered\_watches  
.watcher-history-7-\*  
.watches

I know that these are special indexes.

Could someone explain if it's possible to make persistent changes to them and how?  
By changes I mean modifying number or shards & replicas.

Regards,  
Constantin

Utilising the support contract in place we come to:

If you look at:  
GET .kibana/\_settings  
GET .security/\_settings  
GET .monitoring-es-6-\*/\_settings

You will see dynamic index settings are in place: [https://www.elastic.co/guide/en/elasticsearch/reference/6.2/index-modules.html#dynamic-index-settings](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/index-modules.html#dynamic-index-settings)  
index.auto\_expand\_replicas:  
Auto-expand the number of replicas based on the number of available nodes. Set to a dash delimited lower and upper bound (e.g. 0-5) or use all for the upper bound (e.g. 0-all). Defaults to false(i.e. disabled).

Essentially, depending on how many nodes you have in your cluster, these system indices will expand replicas as per the needs of redundancy.
