Hi Matevz and Bockjoo, Thanks for your help with the investigation. Those cmsxrootd-site[1-3].fnal.gov are connected with our dCache and EOS XROOTD doors. It looks like the following work fine: 1. Without both "-d" and "-m" option: bash-4.2$ time xrdfs cmsxrootd2.fnal.gov:1094 locate /store/test/xrootd/T1_US_FNAL/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/AE237916-5D76-E711-A48C-FA163EEEBFED.root [2620:6a:0:8420::f8]:1094 Manager Read [2620:6a:0:8421::243]:1094 Manager Read [2620:6a:0:8420::f9]:1094 Manager Read real 0m0.440s user 0m0.006s sys 0m0.007s 2.Only with "-m" option: bash-4.2$ time xrdfs cmsxrootd2.fnal.gov:1094 locate -m /store/test/xrootd/T1_US_FNAL/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/AE237916-5D76-E711-A48C-FA163EEEBFED.root cmsxrootd-site1.fnal.gov:1094 Manager Read cmsxrootd-site3.fnal.gov:1094 Manager Read cmsxrootd-site2.fnal.gov:1094 Manager Read real 0m0.442s user 0m0.005s sys 0m0.008s 3.

It goes deep to all levels of XRootD redirectors and only stop after reaching all data servers. As you can see, the first time my query with "-d" and "-m" options took more than over 76 seconds to do the requests and the 2nd time the query returned after 1.86 seconds as the results were still in cache. I have a test setup. It seems "-d" option could work if I reduce one layer of authentication at cmsxrootd-site level, but not sure if this will violate the CMS metadata access policy. I will put this in our test server and see how it goes. Anyway, it will be good to have xrdfs locate with ONLY "-d" option work. On the other hand, I just looked at your monitoring table. Could you please tell if it is possible to get the info without "-d" option? Also, personally I would use "-m" option to make sure to get the hostnames instead of IP addresses. Regards, Yujun 1. ________________________________ From: Bockjoo Kim <[log in to unmask]> Sent: Tuesday, September 19, 2023 3:25 AM To: Matevz Tadel <[log in to unmask]>; Yujun Wu <[log in to unmask]>; Andrew Hanushevsky <[log in to unmask]> Cc: xrootd-l <[log in to unmask]>; Bockjoo Kim <[log in to unmask]> Subject: Re: Help with a xrdfs query puzzle with "xrdfs locate -d" 1093 port is served by the dCache door.
