MinIO问题总结（持续更新）

Q: 之前使用正常，突然使用空间为0B，上传文件也是0B（部署在k8s中）

A:
1、检查pod状态

kubectl get pods

2、如果状态正常，则查看日志

kubectl logs <minio-pod-name>

提示： disk quota exceeded 表示存储卷可能已经达到了其分配的存储限制，无法再写入新的数据
3、解决：
增加存储容量、检查和清理旧数据、优化数据存储策略
4、优化：
设置磁盘使用率的监控和告警，以便在接近存储上限之前收到通知，及时采取行动。

扩容：

kubectl edit pvc <pvc-name> //编辑想要扩展的PVC，找到spec下的resources.requests.storage字段，并将其值更新为新容量大小
kubectl get pvc <pvc-name> //检查PVC的状态，确保其已经成功扩展

Q: 无法上传大文件

A: 配置允许客户端上传的最大请求体大小
