Title:
  Glance image-upload truncates the image.

Status in OpenStack Glance backend store-drivers library (glance_store):
  New

Bug description:
  This may be a DUP of #1240355 but I am not sure.

  I have three hosts which all are connected to the same shared NFS
  datastore and glance configured to use it. I am uploading an image and
  then try to download, but download returns empty string and there is
  an ERROR in the glance/api.log:

  2014-08-25 09:11:01.438 2724 ERROR glance.api.common
