Cause

ElasticSearch 資料發生問題  

Resolution

命令使用 delladmin 帳戶在 PowerFlex Manager CLI 上執行。

 

步驟 1 = 釋放彈性搜尋資料庫中的空間（最大大小應為 5G）

   

  • curl 'localhost:9200/_cat/indices?v’

 

如果有許多 snmp 設陷索引，如果您同意，可以刪除較舊的設陷：

 

  • curl -X DELETE localhost:9200/snmp-traps-YYYY.MM.DD (this deletes a specific date)

 

或者您可以通過以下命令將它們全部刪除：

 

  • curl -X DELETE 'http://localhost:9200/syslog* [localhost]'

 

步驟 2 = 移除彈性搜尋記錄。

  • sudo systemctl status Elasticsearch
sudo systemctl stop Elasticsearch

cd /var/log/elasticsearch (note: Do not delete vxfm-es-cluster.log)
rm -rf *log.gz*
rm -rf *gc.log*
rm -rf *showlog.log*

Systemctl start Elasticsearch
sudo systemctl status Elasticsearch


步驟 3 = 刪除 ElasticSearch 中的所有資料：

*警告：客戶將遺失所有歷史警示、資源的效能指標，以及系統記錄資料。

 

  • curl -XDELETE localhost:9200/_all

 

檢查狀態並停止 rsyslog 服務。

 

systemctl status rsyslog

systemctl stop rsyslog

 

再試一次並啟動系統記錄服務：

systemctl start rsyslog
