From: Sonia Ghanekar Date: Mon, 2 Nov 2015 21:58:42 +0000 (-0800) Subject: Using extra-specs in cloned vols for Nimble driver X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=8484a234a8047019627184efbc2656f6ce2cb06d;p=openstack-build%2Fcinder-build.git Using extra-specs in cloned vols for Nimble driver This patch uses the set extra-specs while cloning a volume. All existing extra-specs: 'nimble:encryption', 'nimble:perfpol-name' and 'nimble:multi-initiator' are being reflected in the cloned volume. In the existing code, the extra-specs were not being considered while cloning volumes; the parent volume attributes were used directly in the cloned volume. This patch uses the extra-spec values if they are set or if not then uses the default values for the same.
