上面的日志其实都没有啥帮助：
主要是这个日志最主要：

iSCSI Initiator File /etc/iscsi/initiatorname.iscsi: oslo_concurrency.processutils.ProcessExecutionError: Unexpected error while running command.  
$ R9 I8 j. o0 `
9 f) E9 d2 f& d9 c这个呢，我便去节点上看看，想这个怎么回事呢？难道要启动iscsid服务？
带着这个问题，我就去检查：initiatorname.iscsi

4 t5 a8 t% j1 R[root@compute3 ~]# vim /etc/iscsi/iscsid.conf
anaconda-ks.cfg  .bash_history    .bash_logout     .bash_profile    .bashrc          .cache/          .cshrc           .lesshst         .ssh/            .tcshrc          .viminfo   

只有iscsid.conf 文件，那就是没有生成这个文件：
/ s0 c/ |# t5 W# b那我只能尝试创建这个文件：   会不会是iscsid这个服务给创建的呢？
于是检查状态：
[root@compute3 ~]# systemctl status iscsid.service
