elasticsearch - 删除未分配的Elasticsearch分片

Question

我的安装运行正常，但是由于其中显示了2个“未分配”的未分配碎片，因此一个索引显示黄色运行状况。如何删除这些多余的碎片？我当前的设置是0个副本和2个分片。

curl -XGET 'http://localhost:9200/_cluster/health/tags?level=shards&pretty=true'
{
  "cluster_name" : "elasticsearch_inspire",
  "status" : "yellow",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 2,
  "active_shards" : 2,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 2,
  "indices" : {
    "v1_tags" : {
      "status" : "yellow",
      "number_of_shards" : 2,
      "number_of_replicas" : 1,
      "active_primary_shards" : 2,
      "active_shards" : 2,
      "relocating_shards" : 0,
      "initializing_shards" : 0,
      "unassigned_shards" : 2,
      "shards" : {
        "0" : {
          "status" : "yellow",
          "primary_active" : true,
          "active_shards" : 1,
          "relocating_shards" : 0,
          "initializing_shards" : 0,
          "unassigned_shards" : 1
        },
        "1" : {
          "status" : "yellow",
          "primary_active" : true,
          "active_shards" : 1,
          "relocating_shards" : 0,
          "initializing_shards" : 0,
          "unassigned_shards" : 1
        }
      }
    }
  }
}

我最近遇到了一个问题，其中ES进程在所有节点上都重新启动，并且我有一些未分配的分片(集群运行状况为红色)。
我做了以下手动分配分片的工作，这对我来说是窍门(无需重新启动)

curl -XPOST 'localhost:9200/_cluster/reroute' -d '{
  "commands": [
    {
      "allocate": {
        "index": "INDEXNAME",
        "shard": "SHARDNUMBER",
        "node": "PICKANODE",
        "allow_primary": 1
      }
    }
  ]
}'
