Hi John, I have a related question on this issue for you regarding RiakCS. In 4.2.0 release, backup snapshot to S3 is done through your s3xen plugin, where S3 single part upload API is used. If customer is using RiakCS as their S3 object store, can they still backup snapshot larger than 5GB? Based on your comments, it seems that they should be able to?

Darren, Since S3/Riak CS can receive the contents of a file out of order and re-assemble upon completion of transfer of all parts, the underlying driver uses the TransferManager which automatically breaks files up into multi-part uploads to increase parallelism to decrease the time required to upload to the object store. Therefore, multi-part uploads are not employed solely to upload files larger than 5 GB. Have you tried to upload the file to Riak CS using s3cmd outside of CloudStack?

I actually don't think this is a CloudStack issue but more of an issue with Riak-CS. I was just wondering if anybody has specifically ran the setup or knows more about Riak-CS and can tell me whats up. I've been trying off and on for the last week to try to get this working with 4.2 but it just keeps failing. I think I'll just try ceph rados gateway if I can't get this working.

If we register template more than 5GB we use multipart upload to push the files to Riak. But this does not work for snapshots and volumes. This will be fixed in CS4.2.1 . But for template registration it should work fine.

Reason: disconnected I'm able to interact with Riak-CS with s3cmd just fine but its not using multipart. I think I'm going to try to download a new s3cmd that does multipart and see if even that will work. Darren
