I keep running into this error when attempting to create a volume from an image: ProcessExecutionError: Unexpected error while running command.

'rbd import' tries to stat the file first, and only gets to this error if the stat reported size 0. Is the image (and thus temp file) size 0, or is it not a regular file?
Looking at the cinder code, a temporary file is created, the blocks copied down from the glance connection and then the rbd command is run (without there being a file close on the temp file. Does the file need to be properly closed before the rbd command is run? Would a flush on the file handle be sufficient? Any suggestions would be welcome.
'rbd import' does fsync itself so that it can get extent information from fiemap.
