This is a simple test scenario to help validate your encryption. It assumes an LVM based Block Storage server.
Perform these steps after completing the volume encryption setup and creating the volume-type for LUKS as described in the preceding sections.
Create a VM:
$ nova boot --flavor m1.tiny --image cirros-0.3.1-x86_64-disk vm-test
Create two volumes, one encrypted and one not encrypted then attach them to your VM:
$ cinder create --display-name 'unencrypted volume' 1 $ cinder create --display-name 'encrypted volume' --volume-type LUKS 1 $ cinder list +--------------------------------------+-----------+--------------------+------+-------------+----------+-------------+ | ID | Status | Name | Size | Volume Type | Bootable | Attached to | +--------------------------------------+-----------+--------------------+------+-------------+----------+-------------+ | 64b48a79-5686-4542-9b52-d649b51c10a2 | available | unencrypted volume | 1 | None | false | | | db50b71c-bf97-47cb-a5cf-b4b43a0edab6 | available | encrypted volume | 1 | LUKS | false | | +--------------------------------------+-----------+--------------------+------+-------------+----------+-------------+ $ nova volume-attach vm-test 64b48a79-5686-4542-9b52-d649b51c10a2 /dev/vdb $ nova volume-attach vm-test db50b71c-bf97-47cb-a5cf-b4b43a0edab6 /dev/vdc
On the VM, send some text to the newly attached volumes and synchronize them:
# echo "Hello, world (unencrypted /dev/vdb)" >> /dev/vdb # echo "Hello, world (encrypted /dev/vdc)" >> /dev/vdc # sync && sleep 2 # sync && sleep 2
On the system hosting cinder volume services, synchronize to flush the I/O cache then test to see if your strings can be found:
# sync && sleep 2 # sync && sleep 2 # strings /dev/stack-volumes/volume-* | grep "Hello" Hello, world (unencrypted /dev/vdb)
In the above example you see that the search returns the string written to the unencrypted volume, but not the encrypted one.
