Hi, Running 15 node ElasticSearch 0.19.11 cluster on EC2. I'd like to set the delete\_all\_indicies option to prevent anyone from doing that. Two questions. 1. What's the correct way to set that flag? That goes in elasticsearch.yml? Is it as simple as: action.disable\_delete\_all\_indices: true 1. Is there a way to set that without restarting servers? Do I need to restart all the servers in the cluster for that option to take effect? Thanks. -Sean -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

If you have a bigger cluster, and only one or two nodes with HTTP enabled which get hit by requests directly, I guess it's fine to only restart those nodes. I haven't tested it, but it should be enough. ## Best regards, Radu [http://sematext.com/](http://sematext.com/) -- Elasticsearch -- Solr -- Lucene -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
