Hi, Peter Thanks for sending me the config files. The main difference between the configurations you sent me and the one I used is the olb/path w /some/path directive. After including this in my configuration, I can now update a file which already exists on one of the nodes, but I still cannot create a new file through the redirector. As before, I can create new files if I try writing directly to a leaf node xrootd.
