修改索引副本
bash
root@es-node3:~# curl -XPUT http://192.168.1.136:9200/es-syslog-2023.08.26/_settings -H "Content-Type: application/json" -d '{
> "settings": {
> "index": {
> "number_of_shards": 3,
> "number_of_replicas": 2
> }
> }

{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Can't update non dynamic settings [[index.number_of_shards]] for open indices [[es-syslog-2023.08.26/5EEqjFuGTBe6_wdyoBeV7g]]"}],"type":"illegal_argument_exception","reason":"Can't update non dynamic settings [[index.number_of_shards]] for open indices [[es-syslog-2023.08.26/5EEqjFuGTBe6_wdyoBeV7g]]"},"status":400}r看起来您正在尝试修改一个已经打开的索引的非动态设置index.number_of_shards。在默认情况下，Elasticsearch不允许在索引处于打开状态时修改非动态（不可更改）的设置。
curl -XPOST http://192.168.1.136:9200/es-syslog-2023.08.26/_close
使用以下命令来修改索引的设置：
curl -XPUT http://192.168.1.136:9200/es-syslog-2023.08.26/_settings -H "Content-Type: application/json" -d '{
"settings": {
"index.number_of_shards": 3
}
}'
重新打开索引。
curl -XPOST http://192.168.1.136:9200/es-syslog-2023.08.26/_open
迁移分片
curl -XPOST -H "Content-Type: application/json" -d '{
