Comment 1 for bug 1537721

> It has 10 obects in Swift, but should has only one (size is less than 5G)

The v2 client doesn't seem to send the size to the server at all:

 PUT /v2/images/36e7def9-f734-4e09-9feb-872e58648a01/file HTTP/1.1.
 Host: 10.0.0.100:9292.
 Accept-Encoding: gzip, deflate.
 Transfer-Encoding: chunked.
 Accept: */*.
 X-Auth-Token: xxx
 Connection: keep-alive.
 User-Agent: python-glanceclient.
 Content-Type: application/octet-stream.

so the server, not having anyway to know the amount of bytes it's going to receive will segment the upload.
(This may be a client bug.)

I haven't been able to reproduce this on devstack (so far):
