错误信息

查看容器日志后，报错信息如下

ERROR Unable to use the drive /minio_data: Drive /minio_data: found backend type fs, expected xl or xl-single - to migrate to a supported backend visit https://min.io/docs/minio/linux/operations/install-deploy-manage/migrate-fs-gateway.html: Invalid arguments specified

解决方法

错误表明 MinIO 试图使用 /minio_data 作为存储后端，但发现它的存储类型是 fs（文件系统模式） ，而 MinIO 期望的是 xl 或 xl-single（分布式或单节点 XL 模式） 。因此，MinIO 不能正常启动。

修改前

command: minio server /minio_data --console-address ":9001"

修改后

command: minio server /minio_data/minio{1...4} --console-address ":9001"

关键变化

• 这里 /minio_data/minio{1...4} 代表 4 份存储路径，符合 MinIO 的 XL 模式 要求（至少 4 份）。
• 这样，MinIO 就不会再错误地尝试使用 FS 模式。
