minio 4*4 集群 故障测试

作者：互联网

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

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
