Using grizzly on centos 6.4, attached volumes are shown with wrong device names in cinder. E.g. I have this volume wich I attach, cinder tells me its attached as /dev/vdb:
 |         attachments          | [{u'device': u'/dev/vdb', u'server_id': u'3318b373-8792-4109-b65c-ee138dcd525f', u'id': u'c424719d-1031-4e29-8086-8a62b385d99a', u'volume_id': u'c424719d-1031-4e29-8086-8a62b385d99a'}] |

 but on the machine (ubuntu 12.04 cloud image) the device is /dev/vdc:

root@u15:~# cat /proc/partitions 
major minor  #blocks  name

 253        0    2097152 vda
 253        1    2088450 vda1
 253       16        400 vdb

-> attaching volume to instance:
root@u15:~# cat /proc/partitions 
major minor  #blocks  name

 253        0    2097152 vda
 253        1    2088450 vda1
 253       16        400 vdb
 253       32    1048576 vdc
 253       33    1047552 vdc1

Maybe this is not cinders fault, as it the volume seems to be the second
attached storage device? could be due to ubuntus image, but still, the
device name is wrong.
