[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 

The spec at


was not approved in December on the grounds that the DRBD Cinder driver 


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!
