Hi Daniel, The current feature freeze exceptions are being gathered for code reviews whose specs/blueprints are already approved. Since your spec does not appear to be approved, you would have to first request a spec freeze exception, but I believe it is too late for that now in Kilo. I sent the Spec Freeze Exception request in January: http://lists.openstack.org/pipermail/openstack-dev/2015-January/054225.html Regards, Phil -- : Ing.

[openstack-dev] [nova] Request Spec Freeze Exception (DRBD for Nova)
Hello all, in Paris (and later on, on IRC and the mailing list) I began to ask around about providing a DRBD storage driver for Nova. This is an alternative to using iSCSI for block storage access, and would be especially helpful for backends already using DRBD for replicated storage. The spec at https://review.openstack.org/#/c/134153/ was not approved in December on the grounds that the DRBD Cinder driver https://review.openstack.org/#/c/140451/ should be merged first; because of (network) timeouts during the K-1 milestone (and then merge conflicts, rebased dependencies, etc.) it wasn't merged until recently (Jan 5th). Now that the Cinder driver is already upstream, we'd like to ask for approval of the Nova driver - it would provide quite some performance boost over having all block storage data. Thank you for your kind consideration! Regards, Phil -- : Ing.
