Subject [jira] [Created] (CLOUDSTACK-8640) Uploads to S3 Secondary Storage fail, stay at 0% completed

Wido den Hollander created CLOUDSTACK-8640:
----------------------------------------------

             Summary: Uploads to S3 Secondary Storage fail, stay at 0% completed
                 Key: CLOUDSTACK-8640
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8640
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: SystemVM
    Affects Versions: 4.5.1, Future
         Environment: Ceph RADOS Gateway with Civetweb as Secondary Storage
            Reporter: Wido den Hollander
            Assignee: Wido den Hollander


I noticed this after upgrading to 4.5.2 (build from 4.5 branch).

Uploads never completed when a template was downloaded en directly uploaded to S3 secondary
storage provided by Ceph's RADOS Gateway using Multipart.

After searching for hours I found this: http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/event/ProgressEvent.html#getBytesTransferred()

The ProgressEvent of the returned that 0 bytes had been transferred. But when using the getBytes()
method it actually works.

The upload succeeds, but we check if the amount of uploaded bytes is equal or more then what
we expected. If not, we say the upload failed.

This happens inside S3TemplateDownloader (which really needs some fixes btw....)

Tracing this down if it's related to Ceph or actually something in S3TemplateDownloader.

I also tried the Amazon SDK 1.9.34, but that didn't make a different.
