> In the swift filesystem for openstack, a rename operation on a partitioned file uses
the swift COPY operation, which attempts to consolidate all of the partitions into a single
object.  This causes the rename to fail when the total size of all the partitions exceeds
the maximum object size for swift.  Since partitioned files are primarily created to allow
a file to exceed the maximum object size, this bug makes writing to swift extremely unreliable.
