Recovering from an unexpected error: The page range specified is invalid.

 

If your file is uploaded completely and then error occurred at the last it is possible this error occurred due to a mismatch between page blob upload. There are two things you can try:

1. Try the same command little later and it may work.

2. Please use the following blog with entries as described after the blog:

  <csupload

    uploadBlockSizeInKb="512"

    maxUploadThreads="1"

If you try a few time this should fix your problem. As VM Role is still in BETA and work is being done to root out such issues.
