Re: [Openstack] Openstack API - Volumes?
Now that I have had a chance to look into this a little more, I realize that I had missed the connection of talking about the volume functionality missing in the Openstack Rest API (versus the EC2 api that was already there). Justin: Sorry I'm a bit late to the game on this, but is there a blueprint/documentation for the API that I could take a look at? And I agree with the others that it would be nice to get the Openstack API side of things moving since it is a pretty core element and should be in Cactus, but like I said, I'm not a core dev for nova, so what needs to be done to get this going? I also think that since this is a core piece that doesn't exist already, I don't think it should be an extension and we should work on getting it in there. -- Chuck On Mon, Mar 21, 2011 at 10:14 PM, Adam Johnson adj...@gmail.com wrote: Hey everyone, I wanted to bring up the topic of volumes in the OpenStack API.

Re: [Openstack] Openstack API - Volumes?
I am happy to do a first pass over the volume API. I can do it as an extension or not, whatever is more likely to be merged. My personal feeling is that we shouldn't use extensions for something this core, but we can do a 'full lifecycle' if we want: I'll write it as an extension, we work on it as a community, then we promote it into core if/when it is ready. The thing I don't like about the extension promotion process is that it breaks clients when the volume API is promoted. But I'm all for trying it and seeing what happens.

Re: [Openstack] Openstack API - Volumes?
Describing full Volume API as an extension may work in the short term. Long term though we're moving towards having a suite of APIs. From this perspective adding an extension to OpenStack Compute API seems a little strange to me. But it could work short term, my concern is that we should really be thinking of Volumes as a core API, not additional features to Compute. Certainly we may need to extend compute to do things like mount/unmount a volume. -jOrGe W.

Version changes by definition break clients anyway. The extension will stay an extension in 1.1 always, even if the extension is promoted in 2.0. So clients built against 1.1 will continue to consume the extension as is and will not be broken -- code will have to be changed regardless to move to 2.0 at this point the extension is core. -jOrGe W. ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
Re: [Openstack] Openstack API - Volumes?
Hey Chuck, Thanks for the response. We are very interested in this project as well, and may want to contribute. We're currently evaluating options such as Sheepdog and others to see if they fit the bill. In order to fully evaluate these options, it would be great to have *some* API support in the project. I think adding volumes as an extension short term seems like a good idea. Whatever it takes to get something in there, so we can get our hands dirty and experiment some more.

Re: [Openstack] Openstack API - Volumes?
Hey Adam, As far as I understand it, there is already basic volume support within nova, and that there are currently some suggested changes for the current API. We are planning to fit within that API as much as possible, and work with the community to make any changes that may need to be made (an easy example is snapshot support for snapshots in swift). Most of our team will be at the developers summit, and look forward to discussing it with others then. -- Chuck On Tue, Mar 22, 2011 at 8:00 PM, Adam Johnson adj...@gmail.com wrote: Hey Chuck, Thanks for the response.

Re: [Openstack] Openstack API - Volumes?
Sounds great, We are basing our developments off of Justin's API work, just wanted to get a consensus from the community on his approach, and see how we can get it in as an optional component so that people can start getting their hands dirty. We're also interested in the snapshots support as well. Have you started working on this feature, as well as the block storage project? Could you share some timelines with us so that we can maybe collaborate? Thanks!
