commands arch 集群 cas 故障 from cati 服務 題解 elasticsearch 集群indices 分片狀態INITIALIZING,集群狀態為: yellow
故障現象
GET /_cat/shards/7a_cool
7a_cool 5 r STARTED 4583018 759.4mb 10.2.4.21 pt01-pte-10-2-4-21
7a_cool 17 r INITIALIZING 10.2.4.22 pt01-pte-10-2-4-22 《==異常分片
解決辦法
1:關閉異常分片主機es 服務;
登陸pt01-pte-10-2-4-22 主機 ,/etc/init.d/elasticsearch stop ,發現分片自動遷移至其它主機,但是狀態還是在初始化狀態,問題依舊存在;
2:指定分片做主機遷移,
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"
}
}
]
}
發現報錯:報錯信息如下:
{ "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 }
以上信息顯示, state = INITIALIZING ,不能移動。
3:修改分片副本數量
首先修改indices 副本數為0
此時集群開始調整集群分片,調整完成後集群狀態變成:green
PUT 7a_cool/_settings
{
"index": {
"number_of_replicas": "0"
}
}
然後再修改集群indices狀態為1
PUT 7a_cool/_settings
{
"index": {
"number_of_replicas": "1"
}
}
集群會再次調整副本數量,調整完成後集群狀態依然是:green ,問題解決。
