ISCSI 网络磁盘搭建

## **ISCSI 网络磁盘搭建** ### 1、介绍 iSCSI，即Internet SCSI，它是一种基于IP Storage理论的新型存储技术，该技术将存储行业广泛应用的SCSI接口技术与IP网络技术相结合，可以在IP网络上构建SAN。简单地说，iSCSI就是在IP网络上运行SCSI协议的一种网络存储技术。懒猫微服连接iSCSI可用作网络备份和网络磁盘挂载存储

2.1、服务搭建在服务器上添加一块硬盘或划分一个分区 ```bash [root@localhost ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 20G 0 disk ├─sda1 8:1 0 1G 0 part /boot └─sda2 8:2 0 19G 0 part ├─centos-root 253:0 0 17G 0 lvm / └─centos-swap 253:1 0 2G 0 lvm [SWAP] sdb 8:16 0 12G 0 disk ``` 如果有多个空闲分区，可将其组成一个RAID 一起使用 ```bash # mdadm -Cv /dev/md0 -l 0 -n 1 /dev/sdb --force # mdadm -D /dev/md0 ``` 配置iSCSI服务端 ```bash # yum install targetcli -y # systemctl start target && systemctl enable target # targetcli /> ls /> cd /backstores/block /backstores/block> create disk0 /dev/sdb /> cd /iscsi /iscsi> create iqn.2025-08.com.target:susan /iscsi> cd /iscsi/iqn.2025-08.com.target:susan/tpg1/luns /iscsi/iqn.20...san/tpg1/luns> create /backstores/block/disk0 /iscsi/iqn.20...san/tpg1/luns> cd /iscsi/iqn.2025-08.com.target:susan/tpg1/acls /iscsi/iqn.20...san/tpg1/acls> create iqn.2023-01.cloud.lazycat:lzcbox-d29dac66 /iscsi/iqn.20...san/tpg1/acls> cd /iscsi/iqn.2025-08.com.target:susan/tpg1/portals/ /iscsi/iqn.20.../tpg1/portals> delete 0.0.0.0 3260 /iscsi/iqn.20.../tpg1/portals> create 192.168.1.249 3260 /iscsi/iqn.20.../tpg1/portals> cd / /> ls /> exit ``` 注意创建目标ACL时，需要匹配微服主机的ISCSI地址，具体查询： ```bash lzcbox-d29dac66 ~ # cat /lzcsys/var/pd/iscsi/initiatorname.iscsi InitiatorName=iqn.2023-01.cloud.lazycat:lzcbox-d29dac66 ``` #### 2.2、连接服务创建完成后，打开微服设置 ——> 网络硬盘 ——> 添加网络硬盘，输入服务器IP地址即可。 ![image-20250808124524221](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808124524221.png?imageSlim)

![image-20250808125548026](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808125548026.png?imageSlim) ![image-20250808125554859](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808125554859.png?imageSlim) 创建LUN完成后，新建iSCSI ，可以启用CHAP验证 ![image-20250808125608160](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808125608160.png?imageSlim) 将刚才创建的LUN设备映射到当前的iSCSI 中。

5.1、镜像拉取在github仓库中拉取镜像，镜像地址：`ghcr.io/coracoo/d-tgtadm:latest` 也可以从其他地方拉取 ``` crpi-xg6dfmt5h2etc7hg.cn-hangzhou.personal.cr.aliyuncs.com/cherry4nas/d-tgtadm:latest ``` ![image-20250808125837850](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808125837850.png?imageSlim) #### 5.2、容器创建拉取成功后，将其添加到容器中并创建 ![image-20250808125854057](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808125854057.png?imageSlim) 端口有两个：3260（iSCSI端口），13260（web管理端口） ![image-20250808125909559](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808125909559.png?imageSlim) 【文件夹路径】：默认提供了/app/config和/app/iscsi两个路径，前者用来存储配置文件、日志，后者用来存储虚拟磁盘。 ![image-20250808125921947](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808125921947.png?imageSlim) 其他的地方不用变 ![image-20250808125933363](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808125933363.png?imageSlim) 需要注意的是，网络从默认的Bridge 修改为 host ![image-20250808125943534](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808125943534.png?imageSlim) 修改完成后直接创建 ![image-20250808125952564](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808125952564.png?imageSlim) 输入IP地址加端口号即可登录 ![image-20250808130008150](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808130008150.png?imageSlim) #### 5.3、软件配置先新建一个磁盘，使用QEMU方式创建 ![](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808130026884.png?imageSlim) 磁盘创建完成后新建一个Target ![image-20250808130059530](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808130059530.png?imageSlim) 最后创建LUN，将刚才的磁盘和Target关联起来 ![image-20250808130110114](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808130110114.png?imageSlim) #### 5.4、连接服务打开微服设置 ——> 网络硬盘 ——> 添加网络硬盘，输入服务器IP地址即可。 ![image-20250808130124210](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808130124210.png?imageSlim) ![image-20250808130131066](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808130131066.png?imageSlim) Github 地址： [GitHub - coracoo/d-tgtadm: 将 NAS 空间提供给PC扩容，一款现代化的 NAS iSCSI 管理工具，基于docker使用](https://github.com/coracoo/d-tgtadm) ### 6、格式化磁盘将其挂载到网盘 ![image-20250808130209165](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808130209165.png?imageSlim) ![image-20250808130215642](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808130215642.png?imageSlim) 格式化完成后需要将其断开重连，重新挂载一下，网盘才能正常识别 ![image-20250808130234896](https://dl.playground.lazycat.cloud/guidelines/395/image-20250808130234896.png?imageSlim)
