Hi, When properly set with the right configuration and the right system and OpenStack packages, Cinder, OS-Brick, and Nova no longer have race conditions with iSCSI operations anymore (single or multipathed), not even with drivers that do "shared target". So I would assume that Glance won't have any issues either as long as it's properly making the Cinder and OS-Brick calls.
