Hi, We've set up GridFTP (4.2.1) on several nodes across our WAN (2 sites) using the quickstart documentation.
We are not seeing any issues while transferring large files but when we do a batch transfer (globus-url-copy) with lots of small files (LOSF) then we have problems. The debug/verbose output is the following : ---------------------------------------------------- error transferring: globus_ftp_client: the server responded with an error 500 500-Command failed. : globus_l_gfs_file_open failed. 500-globus_xio: Unable to open file /path/to/data/losf/small0aAEq8QsYSCJ 500-globus_xio: System error in open: Permission denied 500-globus_xio: A system call failed: Permission denied 500 End. error: There was an error with one or more transfers. --------------------------------------------------- Note, that this error is intermittent as the same transfer works sometimes. We would appreciate some advice info on what could be the problem and also how to investigate further. Thanks Arn
