Fixed In Version:	ceph-0.94.2-9.el7cp	Doc Type:	Bug Fix
Doc Text:	Under certain circumstances, copying an object onto itself (for example, to change its metadata) produced a truncated object. The truncated object had correct metadata, including the original size, but the underlying RADOS object was smaller. Consequently, when a client attempted to fetch the object, it received less data than indicated by the Content-Length header, blocked for more, and eventually timed out. This bug has been fixed, and the object can now be read successfully in the aforementioned scenario.	Story Points:	---
