title: gsutil copy to storage failing
body: <p>i'm working in a instance at us-central1-a zone and I can't copy a ~200GB file.</p>
  
  <p>i've tried :</p>
  
  <ul>
  <li>gsutil -m cp -L my.log my.file gs://my-bucket/</li>
  <li>gsutil -m cp -L my.second.log my.file gs://my-bucket2/</li>
  </ul>
  
  <p>And after several "catch ups" I get the following error: </p>
  
  <p>CommandException: Some temporary components were not uploaded successfully. Please retry this upload.
  CommandException: X files/objects could not be transferred.</p>
  
  <p>Any clues?</p>
  
  <p>Thanks</p>
