在 Mapping 里面,将 dynamic 参数设置成 strict 可以拒绝索引包含未知字段的文档。 此条 Tips 由 medcl 贡献。

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:106

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,
