Comment 4 for bug 1591081

In this case the issue is happening in 6.1. The customers steps are:

Upload an image larger than the Glance image size(300gb). The image file fails(322gb). RBD receives some of the data(256gb) but doesn't get the entire image. Glance allows the end user to delete the image in glance, but the image does not get deleted out of Ceph.

Errors that lead to tagging this issue as the cause:
