注：这次新增计算节点是新增了两台服务器的，这两台服务器是克隆的。

[root@stcs-slave-12 network-scripts]# cat /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.1994-05.com.redhat:9e6042a265ba
 

[root@stcs-slave-13 network-scripts]# cat /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.1994-05.com.redhat:9e6042a265ba
 

 同时也联系了华为存储工程师分析该问题，反馈也是该iscsi的启动器内容一致导致的。

问题处理：

这里修改为报错节点的，修改后的内容如下： 

[root@stcs-slave-13 network-scripts]# vim /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.1994-05.com.redhat:9a6042a265ba

然后重启一下iscsi服务。

[root@stcs-slave-13 huawei]# systemctl restart iscsid

验证：

到这里， k8s集群新增计算节点使用华为iscsi存储创建的pvc存储挂载报错：FailedMount的问题就处理好了，感谢大家的支持！！！！
