HI check this first

cinder-manage service list

you need to have all your cinder service in smile

then do this

Create a Cinder volume. Our example uses m2 for the volume name and is 20GB in size:

cinder create --display-name m2 20

Attach the volume to a running instance. Our examples attaches the ID volume (UUID of the m2 volume) to an Instance named test.

nova volume-attach test <id of="" m2=""> /dev/vdb

Now you login into the vm with name test and check

fdisk -i

it will show the /dev/vdb

now you can create your new partition using the below

fdisk /dev/vdb

mkfs.ext3 /dev/vdb1

mkdir /cinder-test

mount /dev/vdb1 /cinder-test
