Hello, XRootD experts.I have a question about "xrootd.redirect" feature of xrootd.I'm trying to connect the xrootd server (not redirector) to a dCache's xrootd door as a backend.There are many examples, so I'm going to try to follow them, but it doesn't work well.The settings for the xrootd server I set are as follows.xrd.port 1097 all.export /all.role serverxrootd.redirect cms-t2-se01.sdfarm.kr:1094 all /ofs.forward cms-t2-se01.sdfarm.kr:1094 all cms.dfs lookup centralcms.trace allSymptoms that followed these settings are as follows:1. Directory navigation works well. The directory structure of dCache xrootd door on the 1094 port is displayed well.2. Meta commands such as "stat" is work well for files.3. Attempting to open or copy a file (such as root command or xrdcp) results in an Internal Error.[root@cms-t2-se01 xrootd]# xrdfs cms-t2-se01.sdfarm.kr:1097 ls /pnfs/sdfarm.kr/data/cms/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/pnfs/sdfarm.kr/data/cms/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/A64CCCF2-5C76-E711-B359-0CC47A78A3F8.root/pnfs/sdfarm.kr/data/cms/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/AE237916-5D76-E711-A48C-FA163EEEBFED.root/pnfs/sdfarm.kr/data/cms/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/CE860B10-5D76-E711-BCA8-FA163EAA761A.root[root@cms-t2-se01 xrootd]# xrdfs cms-t2-se01.sdfarm.kr:1097 stat /pnfs/sdfarm.kr/data/cms/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/A64CCCF2-5C76-E711-B359-0CC47A78A3F8.rootPath: /pnfs/sdfarm.kr/data/cms/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/A64CCCF2-5C76-E711-B359-0CC47A78A3F8.rootId: 0Size: 240461986MTime: 2017-10-07 00:23:34Flags: 48 (IsReadable|IsWritable)(base) [geonmo@ui10 ~]$ root -l root://cms-t2-se01.sdfarm.kr:1097///pnfs/sdfarm.kr/data/cms/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/A64CCCF2-5C76-E711-B359-0CC47A78A3F8.rootroot [0] Attaching file root://cms-t2-se01.sdfarm.kr:1097//pnfs/sdfarm.kr/data/cms/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/A64CCCF2-5C76-E711-B359-0CC47A78A3F8.root as _file0...Error in <TNetXNGFile::Open>: [ERROR] Server responded with an error: [3011] Unable to open /pnfs/sdfarm.kr/data/cms/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/A64CCCF2-5C76-E711-B359-0CC47A78A3F8.root; no such file or directory(TFile *) nullptrxrootd log:[root@cms-t2-se01 xrootd]# tail -n 3 /var/log/xrootd/redir/xrootd.log 190917 18:24:03 22127 XrootdXeq: geonmo.1763304:22@[2001:320:15:124:d6ae:52ff:fe8c:6610] disc 0:00:01190917 18:24:08 25086 XrootdXeq: geonmo.1763339:21@[2001:320:15:124:d6ae:52ff:fe8c:6610] pub IP64 login190917 18:24:08 25086 ofs_open: geonmo.1763339:21@[2001:320:15:124:d6ae:52ff:fe8c:6610] Unable to open /pnfs/sdfarm.kr/data/cms/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/A64CCCF2-5C76-E711-B359-0CC47A78A3F8.root; no such file or directoryHow can I use it as a complete redirect?Regards, -------------------------------------------------------------------------------------------------- Geonmo Ryu / 류건모 Korea Institute of Science and Technology Information (KISTI) Global Science Experimental Data Hub Center (GSDC) 245 Daehak-ro, Yuseong-gu, Daejeon, 305-806, Republic of Korea Tel : +82-42-869-1639, +82-10-4337-9423 Mail : [log in to unmask] / [log in to unmask] -------------------------------------------------------------------------------------------------- ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-L list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-L&A=1
