错误分析：这是OpenStack Folsom版本的一个BUG，造成cinder-volumn服务在节点重启后无法正常启动，最新版本已经修订https://bugs.launchpad.net/cinder/+bug/1175207，可以自己通过修改源代码进行修改，修改如下：
1、打开文件/usr/lib/python2.7/dist-packages/cinder/volume/driver.py
2、找到352行，注释掉old_name=old_name这行代码，修改如下：
self.tgtadm.create_iscsi_target(iscsi_name, iscsi_target,
0, volume_path,
check_exit_code=False)
#old_name=old_name)
3、重启cinder-volumn服务
service cinder-volume restart
服务正常启动，问题解决。
