elasticsearch 集群indices 分片状态INITIALIZING,集群状态为: yellow

故障现象

GET /_cat/shards/7a_cool7a_cool 5  r STARTED      4583018 759.4mb 10.2.4.21 pt01-pte-10-2-4-217a_cool 17 r INITIALIZING                 10.2.4.22 pt01-pte-10-2-4-22  《==异常分片

解决办法

1:关闭异常分片主机es 服务;

        登陆pt01-pte-10-2-4-22 主机  ,/etc/init.d/elasticsearch  stop ,发现分片自动迁移至其它主机,但是状态还是在初始化状态,问题依旧存在;   

2:指定分片做主机迁移,

POST /_cluster/reroute{  "commands": [    {      "move": {        "index": "7a_cool",        "shard": 17,        "from_node": "pt01-pte-10-2-4-22",        "to_node": "pt01-pte-10-2-4-25"      }    }  ]}
发现报错:报错信息如下:
{  "error": {    "root_cause": [      {        "type": "illegal_argument_exception",        "reason": "[move_allocation] can't move 17, shard is not started (state = INITIALIZING]"      }    ],    "type": "illegal_argument_exception",    "reason": "[move_allocation] can't move 17, shard is not started (state = INITIALIZING]"  },  "status": 400}
    以上信息显示, state = INITIALIZING ,不能移动。   

3:修改分片副本数量

    首先修改indices 副本数为0     此时集群开始调整集群分片,调整完成后集群状态变成:green
PUT 7a_cool/_settings{  "index": {        "number_of_replicas": "0"        }}
然后再修改集群indices状态为1
PUT 7a_cool/_settings{  "index": {        "number_of_replicas": "1"        }}
集群会再次调整副本数量,调整完成后集群状态依然是:green ,问题解决。
