我用CentOS-7-x86_64-LiveGNOME-1511.iso 跑live DVD，救援资料用iSCSI
很多时候超好用，但是CentOS6用tgtd都没问题，现在7版改用targetd，
却一直失败。

以上是targetcli设定状况，现在我要看status
[root@localhost ~]# systemctl start targetd
[root@localhost ~]# systemctl status targetd

我搞不懂/etc/target/targetd.yaml是要干嘛，但我还是把root密码丢进去再启动

[root@localhost ~]# systemctl status targetd

问题好像越来越大了，请问有人知道这是怎模回事吗？
