Hi Mike,

The documents are very helpful. A follow-up question, in the final release of Grizzly, would I expect to see V1 or V2 Cinder api? If V2, would the Nova os-volume be updated to talk to Cinder v2 api as well?

Thanks.

James

Subject: Re: [Openstack] Grizzly Cinder Volume API vs. Nova os-volumes api

Hi James,

It looks like Nova will continue to have os-volume support, but that'll only be able to talk to Cinder API v1. And a little note unrelated to your question, Cinder API v2 will be available through cinderclient in its next release (very soon), but you can try it now from the github repo [1], and of course making direct calls to the cinder api server in G releases.

Things aren't terribly different in the request/responses, but I'm trying to ease the pain with some docs for v1 and v2 that are in review [2][3]. I've generated some PDF's for your convenience though [4][5].

Thanks,

Mike Perez

Hi,

In the latest Grizzly V3,  I can still provision volumes through the Nova os-volumes api. I would like to ask whether the Nova os-volumes will co-exist with Cinder volume api at the final release of Grizzly or we are supposed to migrate to use cinder api directly?

Thanks

James
