The OSLO_LOCK_PATH is not set when installing cinder from tripleo-image-elements/elements/cinder-api/install.d/cinder-source-install/73-cinder-api.

[Zhenzan Zhou (zhenzan-zhou)]

Another option is to set 'lock_path = /var/lock/cinder' in /etc/cinder/cinder.conf [default] section as the official Ubuntu package does.

[Zhenzan Zhou (zhenzan-zhou)]

This should be addressed by bug 1394963.

[Clint Byrum (clint-fewbar)]

Zhenzan Zhou, for future reference, we mark bugs as duplicate in that case.

[wangqiang.sheng (wangqiangsheng)]

解决办法：
 1）配置/etc/cinder/cinder.conf
  Vim /etc/cinder/cinder.conf
  lock_path = /var/lock/cinder

 2）创建文件夹，并赋予权限
  mkdir /var/lock/cinder
  chown cinder:cinder cinder
