Amazon web services AWS Elasticsearch服务：如何删除群集创建索引块？

我最初认为块是自动放置到位的，因为我的集群运行状况是黄色的。我读了关于碎片优化的文章，发现我有很多未分配的碎片。我将节点数增加到2，它变为绿色

GET /_cluster/health?level=indices

但障碍依然存在：

GET /_cluster/settings

我已尝试将_cluster/settings API用于以下所有方面：

PUT /_cluster/settings
{"persistent": {"cluster": {"blocks.create_index": (null and false)}}}

PUT /_cluster/settings
{"persistent": {"cluster.blocks": (null and false)}}

PUT /_cluster/settings
{
  "persistent" : {
    "cluster.blocks.create_index": (null and false)
  }
}
# all return
{"Message":"Your request: '/_cluster/settings' payload is not allowed."}

如何清除该块以便重新编制索引？Elasticsearch服务上的持久设置是否可编辑？我错过了什么

我认为将我的域增加到2个节点将我推到EBS分配上的容量存储：

实例上的磁盘空间是问题所在。
