Two suggestions. 1: I don't know what Cinder wants with /var/lib/nova; search the Cinder configuration for this string and correct it if necessary. 2: If /var/lib/nova is legitimate, perhaps you have an SELinux issue. Cinder is supposed to create the directory as root.

My cinder.conf has a config variable named lock_path which "Defaults to environment variable OSLO_LOCK_PATH". Could be a candidate.

thanks for your kindly answer, i found the reason is that the lock_path=/var/lib/nova/tmp in /etc/nova/nova.conf is wrong,i have changed it to lock_path=/var/lib/cinder/tmp, and now it's working,thank you!
