简介

如题，k8s搭建minio集群（四节点以上），重启后导致minio不能正常使用。

报错日志

API: SYSTEM()
Time: 04:15:35 UTC 02/28/2024
Error: Following error has been printed 3 times.. Detected unexpected drive ordering refusing to use the drive: expecting http://minio-2.minio.ecmp.svc.cluster.local:9000/data6, found http://minio-0.minio.ecmp.svc.cluster.local:9000/data6, refusing to use the drive (*fmt.wrapError)

原因解析

minio集群重启后找不到对应节点的数据，（他虽然是集群，但是数据不是共享的 有点类似于raid），意思就是原来运行minio-0的服务器，只能读minio-0的数据，如果该服务器启动到了minio-1，就没办识别。
不过不要紧张，还是有解决方法滴

先讲下报错的信息，
报错的节点：endpoint=“http://minio-0.minio.ecmp.svc.cluster.local:9000/data6”
报错节点的期望节点：expecting http://minio-2.minio.ecmp.svc.cluster.local:9000/data6
报错节点实际节点：found http://minio-0.minio.ecmp.svc.cluster.local:9000/data6
以上日志提供的信息就是：现在minio-0所在的物理机应该运行minio-2，所以只要把minio-2运行到该节点就可以了。
再分析其他节点的报错找到应该存在的节点即可找到对应关系。
接下来就可以使用k8s的扩缩容+标签的方式让minio启动到对应节点。如果还不清楚可以私信博主
