Thread-topic: ZFS/ZVol + iscsi for volume

Mirantis and Nexenta developed a nova driver to make ZFS ZVOLs mountable on demand. A webinar describing it can be found at http://vimeo.com/32498061
We'd be glad to hear any suggestions on additional functionality here.

We also have a set of patches that is pending to bring ZFS data integrity to Swift objects. https://review.openstack.org/#/c/7524/

Both bring the benefits of ZFS data integrity to Openstack users at a much lower cost than solutions that rely on excessive network replication.
