Subject Re: S3/Swift Problem around Virtual Size
Date Tue, 09 Sep 2014 04:48:34 GMT
Hi Punith,

Thanks for putting in time on this!

So, option 1 occurs after we download the template to S3 or Swift. We then
have to copy it to NFS so that we can determine the virtual size?
Relatively slow, but it would work.

If we went this route, would we then delete that template from the NFS
share since its immediate purpose was so we could figure out the virtual
size or would we leave it on that share?

Option 2 is to allow the user who uploads such a template to specify the
size needed for the root disk (i.e. at least the virtual size of the
template...perhaps larger)?

Does that sound like I understood the options?

Thanks!
Mike
