minio 4*4 集群 故障测试

本文主要是介绍minio 4*4 集群 故障测试,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

因为一个minio有点集群故障(文件写入异常),所以基于官方的理论测试下集群容错性

一个计算规则

4*4 模式的,默认使用的纠删码条纹为16 (官方的模式是取最大,但是计算页面可以调整,对于minio来说这个是自动的),按照套路应该是可以一个server 以及4个盘异常的,不应该出现一个节点异常造成服务不可用的
对于纠删码的奇偶校验可以自己设置,一般集群环境是4

 

 

环境准备

  • docker-compose 文件

故障简单测试

直接停止一个服务节点(会有4个driver 下线),比如docker-compose stop minio1 ,然后通过gateway 以及入口上传文件测试服务的读写情况,之后启动服务之后看看数据恢复情况

服务节点日志

可以查看minio4 可以看到信息

 

 

 

 


查看minio1 的文件恢复情况

 

 

说明

经过以上简单的测试,实际上minio 的集群是靠谱的,核心可能还是在nginx 入口设置有些问题,后续应该调整下,以上只是实际的问题,想验证下理论是否有问题
