1、OS信息 :CentOS Linux release 7.2.1511 (Core)
2、openstack 版本:Liberty
3、cinder后端对接lvm

一、操作
虚拟机挂载由cinder创建的卷,并通过iscsi挂载

重启虚拟机节点后,/dev/disk/by-path路径下,对应由iscsi连接产生的盘符丢失

二、查询
service iscsid status 
Redirecting to /bin/systemctl status  iscsid.service

三、node_acls 认证信息丢失
/etc/target/saveconfig.json文件中的node_acls的认证(用户,密码)信息都丢失了。

四、同时保存在该路径下的 用户 密码信息也都丢失了

/sys/kernel/config/target/iscsi/iqn.2010-10.org.openstack:volume-889fca09-f0f5-42ed-826f-51261418e9ad/tpgt_1/acls/iqn.1994-05.com.redhat:4a683be0abb2/auth

五、求教
该问题是哪些配置有问题,或者版本上存在差异,导致不兼容,还是其余问题。
麻烦知道的告知下,小弟不胜感谢!
