 I have also encountered with similar problem 
 and it may be the reason as log looks similar 
 After hours of struggle i realized that 
the path "/var/lock/cinder" where cinder was a file not a directory 
(worngly created as file)
so deleted file and created cinder dir 

mkdir /var/lock/cinder
chmod 777 /var/lock/cinder/
chown -R cinder:cinder /var/lock/cinder/

[root@controller ~]# ls -lrt /var/lock/
total 0
drwxrwxr-x 2 root   lock    40 Jun 27 13:41 lockdev
drwx------ 2 root   root    60 Jun 22 15:15 iscsi
drwxr-xr-x 2 root   root   100 Jun 24 16:06 subsys
drwxrwxrwx 2 cinder cinder  40 Jul  1 10:15 cinder
drwx------ 2 root   root    40 Jun 27 17:41 lvm

After that able to do successfull volume attach 
[root@controller ~]# ls /var/lock/cinder/* -lrt
