To Reproduce Steps to reproduce the behavior:
In RHOSO environment with Glance S3 backend volume to raw image upload may hang for few days when relatively small image is uploaded:

• On cinder-volume side we can see that image upload started, but no completed
• On Glance side we can see that image upload is in progress
• Inside cinder-volume pod we can see that Glance doesn't pick up data from TCP buffers fast enough
• Network traffic for Glance API node only contains inbound data segments from cinder-volume, it looks like Glance waits for volume to be uploaded to local storage before starting upload to S3 backend.

Expected behavior
Volume to image upload either fail, or completed in reasonable time

Bug impact
This problem is one of the blocker preventing moving deployment to production

Known workaround
None
