Thanks for the bug report! It looks like you set the archive proofs option to a different filesystem, which is not supported by the os.rename() function I used. This is a simple fix to use shutil.move() instead. I am marking this as an enhancement, as I was not expecting people to more the proof files to a different filesystem, but I guess this is what you were referring to by NFS share in https://github.com/tdulcet/Distributed-Computing-Scripts/issues/12#issuecomment-961245195.

While it does not matter in this case, in any future please add the -d/--debug option so I can see all of the output, which I would recommend always adding. BTW, all of those options except -w and -t are saved to the config file, so you only need to provide them the first time the script is run. Also, the -n option is deprecated in favor of -W/--days_work.

Thank you, yes I was referring to NFS, Network File System.

No problem. I attempted to fix this in https://github.com/tdulcet/Distributed-Computing-Scripts/commit/dbd08930b48579241a7526dc1dc3f3982f895a73. Let me know if it now works for you.
