Check for existing files before making the call? And don't issue the call if the file exists. You cannot change stripe attributes on an existing file.

I am implementing the use of llapi_file_open() in my I/O library so I can set the striping. If the file already exists I get the following message on stderr:
error on ioctl 0x4008669a for 'dd.dat' (4): stripe already set
Is there some way to suppress this message? The end-uers of my library will get these messages in stderr of their job and will likely have no clue as to why. My library detects the failed llapi_file_open() and retrys with open64() and spits out its own error message to the library's log.
