所以我用 open-iscsi 设置了一个 iSCSI 磁盘。我可以连接并挂载该磁盘，手动写入和卸载。
我也在 fstab 中输入了相关的定义，即 smt。例如：
dev/sdb1 /storage ext3 defaults,auto,_netdev 0 0
它可以手动安装，没有任何问题。
但是当我运行它时service open-iscsi restart它无法挂载。它在启动时也无法挂载。如果我mount在服务挂载失败后立即写入，它会挂载...
这是初始化脚本的输出：
[ ok ] Unmounting iscsi-backed filesystems: Unmounting all devices marked _netdev.

这是 dmesg 所说的内容（存在连接错误，但我不明白发生了什么）

笔记：
- 由于它是内部网络，因此无需使用用户名/密码即可连接目标
- 我手动添加了节点
iscsiadm -m node -T "iqn.***.c44c07" -p xxx.xxx.xxx.xxx -o new
答案1
在 fstab 文件中使用 UUID 而不是设备名称解决了该问题。
