Hi Friends,

i have created an instance and volume in cinder, but issue facing is that when i tried to attach the volume to the instance i am unable to attach it to instance. Below is the log of /var/log/cinder/api.log.

"2015-05-22 19:02:28.586 2763 ERROR cinder.api.middleware.fault [req-0721c714-cc3e-4b60-a91c-691f4c320d18 b48ac80d198347cd8d0f61eb0a5d7b3e 72d36b9ab4d74d57ae39095f4dbf6d80 - - -] Caught error: Volume driver not ready."

Could someone please help me in it.

BR, Kishore

what volume drivers are you using? You may want to post the driver section of your cinder.conf file.

 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
