commit ab667960ef337538cf777bb0f325cb5d0e865d76

Actually attach a volume to an instance before taking snapshot
In the test test_snapshot_create_with_volume_in_use, the test calls Cinder
"os-attach" for attaching a volume. The "os-attach" to tell Cinder the
volume is attached, but the API doesn't actually attach the volume to an
instance.(Only update volume status in DB)
This is not right test case for taking a snapshot with in-use volume.
In this test, Nova "os-volume_attachment" should be called for volume
attachment.
Also, some Cinder drivers fails assisted snapshot due to this problem.
In order to perform the snapshot properly, this fix is needed.

Title:
Volume Block Device Mapping cannot be found
Status in OpenStack Compute (Nova):
Confirmed
Status in Tempest:
Fix Released
Bug description:
In Short:
Block Device Mapping cannot be found for Tempest online snapshot test on
devstack with remote file system driver.
More Detailed:
Testing Environment is plain kilo head devstack with the included Tempest
testsuite and a new remotefs based cinder driver.
The test:
tempest.api.volume.test_volumes_snapshots.VolumesV2SnapshotTestJSON.test_snapshot_create_with_volume_in_use
produces an error in Nova, stacktrace:

Testing the tests individual steps via manual cli commands (create instance,
attach volume, create online snapshot) works without errors in any of the
involved components.
The error occurs with our Quobyte Driver (in development, see
https://blueprints.launchpad.net/cinder/+spec/quobyte-usp-driver) and
apparently with the existing GlusterFS driver. Both are closely related
(Quobyte build on top of GlusterFS impl) and derived from the remotefs driver.
I don't know if other setups are affected.
