Cause

ElasticSearch 数据存在问题  

Resolution

命令使用 delladmin 帐户在 PowerFlex Manager CLI 上运行。

 

步骤 1 = 释放弹性搜索数据库中的空间（最大大小应为 5G）

   

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

 

如果有许多 snmp 陷阱索引，则可以删除较旧的陷阱（如果您同意）：

 

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

 

或者，您可以通过以下命令将它们全部删除：

 

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

 

步骤 2 = 删除弹性搜索日志。

  • 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


步骤 3 = 删除 ElasticSearch 中的所有数据：

*警告：客户将丢失所有历史警报、资源的性能指标以及系统日志数据。

 

  • curl -XDELETE localhost:9200/_all

 

检查状态并停止 rsyslog 服务。

 

systemctl status rsyslog

systemctl stop rsyslog

 

请重试并启动系统日志服务：

systemctl start rsyslog
