修改index副本数报错 :index read-only / allow delete
原因是磁盘警告了,处理方法:
- 集群加节点扩容;
- 副本数降低;
- 其他:增加磁盘,删除数据;
现将只读打开:
服务器上操作如下:
curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'
Kibana在 Dev Tools中编写:
PUT _all/_settings
{
"index.blocks.read_only_allow_delete": null
}
