ILM:Waiting for [10] shards to be allocated to nodes matching the given filters

Elasticsearch | 作者 harrison520 | 发布于2020年01月11日 | 阅读数:603

使用ILM 实现zabbix历史数据冷热分离,到期的热索引,属性变成warm,但并不会自动迁移到warm节点

"str-000010" : {
"step" : "check-allocation",
"step_time_millis" : 1578727525452,
"step_info" : {
"message" : "Waiting for [10] shards to be allocated to nodes matching the given filters",
"shards_left_to_allocate" : 10,
"all_shards_active" : true,
"actual_replicas" : 1
}

当重数据节点后,warm状态的索引会从hot节点迁移到warm节点,但并不会完全迁移,

请问这个问题解决了吗?我也碰到这个问题了

刚刚自己解决了一个自己遇到的迁移失败的问题,发现是ilm的配置的allocation和index  setting中配置的allocation使用的关键词不同造成的。
 
我在index setting 中使用 includes 关键字:
"index.routing.allocation.include.box": "hot"
 
然后在ilm的cold阶段定义的allocation的关键字是:
"cold": {
        "min_age": "30d",
        "actions": {
          "allocate": {
            "require": {
              "box": "cold"
            }
          }
        }
      }
 
测试使用  _ilm/move来直接进入cold阶段时,发现索引迁移没有动静,显示题目中的信息:
Waiting for [2] shards to be allocated to nodes matching the given filters
 
通过查询此时索引的setting,发现settings中同时包含了include和require两种allocation:
"index.routing.allocation.include.box": "hot",
"index.routing.allocation.require.box": "cold"
 
所以这种情况,索引迁移将无法判断满足条件的节点到底是哪些,所以就处于waiting状态。
 
通过修改ilm的配置,将其中迁移的require改成include之后,调用_ilm/move进入colde阶段,索引分片就可以正常迁移到cold节点了。。
