@bockjoo : thanks for reporting this problem, and sorry for the late reply! > Why is the python open behaving differently from the xrdcp? Now this is an excellent question! Both `xrdcp` and the python bindings call same `C++` implementation of open. Could you please share the error message? Also, it would be great if you could enable client side logging (`export XRD_LOGLEVEL=Dump`) and post here the respective logs? -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1539#issuecomment-1075342063 You are receiving this because you are subscribed to this thread.
