the llapi_file_get_stripe() function does not accept as an input file a soft-link. Check therefore whether the filename provided in File_open is a soft-link, retrieve the real file name in case it is, make sure it is also on a Lustre file system, and use the real filename in the llapi_file_get_stripe() function call instead. Fixes issue open-mpi#12141 Signed-off-by: Edgar Gabriel <[email protected]> (cherry picked from commit c6a6c25)
