Driver Testing
Description
The Cinder community (and other OpenStack projects) have agreed that if a vendor wishes to submit a driver for their particular storage device that said vendor should also be required to set up a third party CI system in their lab which runs Tempest volume tests against their storage device for every Cinder commit, and provides feedback in to Gerrit.
Deadlines
All volume drivers need to have a CI by end of K-3, March 19th 2015. Failure will result in removal in the Kilo release. Discussion regarding this was in the #openstack-meeting IRC room during the Cinder meeting. Read discussion logs

FAQ
What tests do I use?
Use the OpenStack integration test suite Tempest. Specifically you only need to run the volume tests. These tests can be started with the following command from a Tempest repo:
/path/to/tempest/tools/prettytox.sh tempest.api.volume
How do I configure DevStack so my Driver Passes Tempest?
Sample local.conf for devstack setup.
[[local|localrc]] ADMIN_PASSWORD=password MYSQL_PASSWORD=password RABBIT_PASSWORD=password SERVICE_PASSWORD=password SERVICE_TOKEN=password # These options define expected driver capabilities TEMPEST_VOLUME_DRIVER=foo TEMPEST_VOLUME_VENDOR="Foo Inc" TEMPEST_STORAGE_PROTOCOL=iSCSI # These options allow you to specify a branch other than "master" be used CINDER_REPO=https://review.openstack.org/openstack/cinder CINDER_BRANCH=refs/changes/83/72183/4 # Disable security groups entirely Q_USE_SECGROUP=False LIBVIRT_FIREWALL_DRIVER=nova.virt.firewall.NoopFirewallDriver CINDER_SECURE_DELETE=False [[post-config|$CINDER_CONF]] volume_driver=cinder.volume.drivers.foo.FooDriver
When thirdparty CI voting will be required?
Once third party CI's become more common and stable, we'll revisit the subject. For now you can review the discussion on the decision.
