Hi Folks, forwarding snip from other thread - I'm not happy to buy how Matevz is defending this :): On 8/21/14, 3:10 PM, Matevz Tadel wrote: >> Though, I'm curious why we get error in the process despite the fact copy >> finishes well and things get redirected from FNAL to MIT and then to your >> server.

For other tests for example we evaluate stdout from xrdcp and "Error" is in this case false positive to us. Here fresh xrdcp working attempts leading by "Error response": # xrdcp -d 1 -f root://cms-xrd-global.cern.ch//store/test/xrootd/T3_US_Brown//store/mc/SAM/GenericTTbar/GEN-SIM-RECO/CMSSW_5_3_1_START53_V5-v1/0013/CE4D66EB-5AAE-E111-96D6-003048D37524.root /dev/null [2014-08-25 23:11:49.403193 +0200][Error ][XRootD ] [cmsxrootd1.fnal.gov:1094] Handling error while processing kXR_stat (path: /store/test/xrootd/T3_US_Brown//store/mc/SAM/GenericTTbar/GEN-SIM-RECO/CMSSW_5_3_1_START53_V5-v1/0013/CE4D66EB-5AAE-E111-96D6-003048D37524.root, flags: none): [ERROR] Error response.
