MinIO 单节点单硬盘（测试）

CentOS Stream 9
注：因为ext4无法动态调整inode空间占比，所以选择将ext4改为xfs(支持动态调整inode空间占比)

准备

存储https://min.io/docs/minio/linux/operations/install-deploy-manage/deploy-minio-multi-node-multi-drive.html#local-jbod-storage-with-sequential-mounts

Ensure all nodes in the deployment use the same type (NVMe, SSD, or HDD) of drive with identical capacity (e.g. N TB) .

一、准备安装文件

# MinIO Server
wget https://dl.min.io/server/minio/release/linux-amd64/minio
chmod +x minio
sudo mv minio /usr/local/bin/

# MinIO Client
wget https://dl.min.io/client/mc/release/linux-amd64/mc
chmod +x mc
sudo mv mc /usr/local/bin/

二、启动 MinIO Server

mkdir ~/minio
minio server ~/minio --console-address :9090

[root@VM-201-74-centos ~]# minio server ~/minio --console-address :9090
Formatting 1st pool, 1 set(s), 1 drives per set.

三、配置Nginx反向代理

四、纠错 erasure-coding

升级、扩容、缩容、迁移

集群扩容

https://zhuanlan.zhihu.com/p/632471568?utm_id=0

扩展集群：

1. 原有启动命令中，添加新的盘即可，尽量批量并发重启，不要一个个重启。

2、新的盘数量，必须是旧盘数量的倍数（即必须是按照server pool进行扩容）

3、可以在原有节点新增目录（单个drives的pool，即非集群模式，无法扩容，即也无法新增目录）

升级集群：

一般情况，替换minIO二进制文件，重启服务即可

缩容集群：

1、RELEASE.2022-01-25T19-56-04Z开始支持减少server pool

2、mc admin decommission start myminio/ https://minio{01...04}.http://example.net:9000/mnt/disk{1...4}/minio mc admin decommission status myminio，查看进度

3、更新启动命令中的盘，重启服务

恢复：

1、某个盘挂了，直接换个盘重新挂到原来的目录即可。

2、某个节点挂了，换个新节点，使用原来的hostname（ip可以不一样），原来的dns解析到新节点，重新加入集群即可。
