Dear XRootD developers, We had a report of problems accessing XRootD files with ROOT tools. E.g. # /usr/bin/root -l root://red-gridftp12.unl.edu//store/example.root Warning in <TApplication::GetOptions>: file root://red-gridftp12.unl.edu//store/example.root has size 0, skipping We're using xrootd-hdfs at our site, and it turns out the plugin returns zero for both inode and device number, which causes XRootD to flag the file as offline: Flags: 24 (Offline|IsReadable) And ROOT doesn't return stat info for offline files[1], leading to the "size 0, skipping" warning. In an old issue[2], Brian Bockelman asked about modifying the xrootd-hdfs plugin to return 1 for inode number to avoid the issue with files being flagged as offline. I've tested this change, and it does make the root client behave as expected. Are there any negative consequences expected from this fix?
