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。
