Question

我有三个elasticsearch数据节点：

{
  "cluster_name" : "elastic_berries",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 5,
  "number_of_data_nodes" : 3,
  "active_primary_shards" : 50,
  "active_shards" : 100,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0
}

当我删除第一个节点时，我进入这个状态，带有一些delayed_unassigned节点，这是正常的：

{
  "cluster_name" : "elastic_berries",
  "status" : "yellow",
  "timed_out" : false,
  "number_of_nodes" : 4,
  "number_of_data_nodes" : 2,
  "active_primary_shards" : 50,
  "active_shards" : 66,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 34,
  "delayed_unassigned_shards" : 34,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0
}

然后：

{
  "cluster_name" : "elastic_berries",
  "status" : "yellow",
  "timed_out" : false,
  "number_of_nodes" : 4,
  "number_of_data_nodes" : 2,
  "active_primary_shards" : 50,
  "active_shards" : 66,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 34,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0
}

但是，我只请求一个副本，群集应自动分配未分配的分片并返回绿色状态。我必须手动运行此命令：

curl -XPUT＆＃39; localhost：9200 / _cluster / settings＆＃39; -d＆＃39; { ＆＃34;暂态＆＃34; ：{ ＆＃34; cluster.routing.allocation.enable＆＃34; ：＆＃34;所有＆＃34; }＆＃39;

回到绿色状态。有没有办法让这个功能自动化？

Elasticsearch不会自动分配丢失节点的分片
