Details

    Description

      Some warnings were reported in a Microsoft Windows environment (also on retry):

      Note: The file size is 1 smaller than the expected minimum file size.

      On the third attempt, both these tests passed.

      To me, it looks like the error messages are superfluous and should be removed. The recovery of a newly created file is supposed to work (and it apparently did work also in this case) no matter what the contents of the file is.

      The message could be duplicated due to redundant calls (MDEV-25909).
