Are you able to execute cinder operations with a single backend?
It looks like your permissions are not set up correctly.
2013-12-18 18:06:31.910 25883 TRACE cinder.service OperationalError:
(OperationalError) (1045, "Access denied for user
'cinder'@'localhost' (using password: YES)") None None
Are you able to issue commands like "cinder list" ?

Subject: [Openstack] configurate multi-backend in cinder
Hi all

But, when I restart the cinder-volume, I got this issues:
