@kreczko - Have you tried tinkering with the `cms.dfs` configuration: https://xrootd.slac.stanford.edu/doc/dev54/cms_config.htm#_Toc53611070 I'm not entirely sure I'm following but what you describe sure sounds like `cms.dfs lookup central`. You *do* want to make sure you have negative existence caching disabled as updating that cache is relatively race-prone. -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1703#issuecomment-1122745053 You are receiving this because you are subscribed to this thread.
