Hello everyone,

so i have started  a VM and then allocated a 5G volume. Everything goes 
fine until i try to attach the volume to the VM: i am getting this: 
BadRequest: The supplied device path (/dev/vol_1) is invalid HTTP 400 !

Does anyone know what means or how to fix it ? I am using Folsom with 
cinder runing on controller node.

Kind regards,
Fellow Stacker.
