在启动时启动iscsi (systemd)

Question

我在debian 8上，我对linux没有太多的了解，最后一次使用它是有一段时间了。(当系统不存在时)。

当我手动启动open服务时，iSCSI驱动器就会连接到机器上，而不会出现问题(on /dev/sdb)。

现在我正在尝试将它添加到引导周期中。

因此，我确保使用systemctl enable open-iscsi.service启用了open的服务。当我启动时，我没有看到任何关于服务的日志。service open-iscsi status把Active: inactive (dead)还给我，经过一点搜索，这可能意味着没有人需要它，所以它没有启动它。

因此，现在我尝试编辑/etc/fstab，以添加安装，并让systemd生成器生成单元。

我尝试了几个组合应用，我在日志中得到的最好的情况是

mar 17 13:57:45 vm-sdbox5 systemd[1]: Reached target Network is Online.
.... (removed) ....
mar 17 13:59:03 vm-sdbox5 systemd[1]: Job dev-sdb1.device/start timed out.
mar 17 13:59:03 vm-sdbox5 systemd[1]: Timed out waiting for device dev-sdb1.device.
mar 17 13:59:03 vm-sdbox5 systemd[1]: Dependency failed for /mnt/iscsi/zvol.
mar 17 13:59:03 vm-sdbox5 systemd[1]: Dependency failed for Remote File Systems.
mar 17 13:59:03 vm-sdbox5 systemd[1]: Dependency failed for File System Check on /dev/sdb1.

还是没有打开iscsi的痕迹。

举个例子，我试过，我记得：

/dev/sdb1       /mnt/iscsi/zvol        ext4    defaults,x-systemd.requires=open-iscsi.service,x-systemd.wants=open-iscsi.service,_netdev 0 3
/dev/sdb1       /mnt/iscsi/zvol        ext4    defaults,x-systemd.requires=open-iscsi.service,_netdev 0 3
/dev/sdb1       /mnt/iscsi/zvol        ext4    defaults,x-systemd.requires=open-iscsi.service,x-systemd.after=network-online.target 0 3
/dev/sdb1       /mnt/iscsi/zvol        ext4    defaults,noauto,x-systemd.requires=open-iscsi.service,x-systemd.wants=open-iscsi.service,_netdev 0 3

还有几个不同的组合，去除了一些参数

我有问题要查找生成单元的位置(双重检查systemd-fstab-generator)，以确保我的参数确实被使用，并在systemctl list-dependencies中找到它们。

谢谢

检查node.startup = automatic是否存在于/etc/iscsi/iscsid.conf中
