From: Raunak Kumar Date: Mon, 6 Jul 2015 18:40:40 +0000 (-0700) Subject: Add extra spec capability for Nimble Cinder Driver X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=7093d0e290a6916db9eb244c187c56ebfa5b1990;p=openstack-build%2Fcinder-build.git Add extra spec capability for Nimble Cinder Driver Supported Extra Specs are 1. Performance Policy Name nimble:perfpol-name = 2. Encryption nimble:encryption = "yes" Implements: blueprint nimble-add-extra-specs-support Change-Id: I45a18b189746b778f10eecbf669be7943828e28b --- diff --git a/cinder/tests/unit/test_nimble.py b/cinder/tests/unit/test_nimble.py old mode 100644 new mode 100755 index 4e3d02419..8bbcc28c1 --- a/cinder/tests/unit/test_nimble.py +++ b/cinder/tests/unit/test_nimble.py @@ -19,6 +19,7 @@ from oslo_config import cfg from cinder import exception from cinder import test from cinder.volume.drivers import nimble +from cinder.volume import volume_types CONF = cfg.CONF @@ -59,13 +60,33 @@ FAKE_NEGATIVE_NETCONFIG_RESPONSE = {'err-list': {'err-list': [{'code': 13}]}} FAKE_CREATE_VOLUME_POSITIVE_RESPONSE = {'err-list': {'err-list': -
