Dear XRootD experts, I have a problem trying to use the third party copy functionality in XRootD. Indeed, when I try to transfer an Alice file from lxplus.cern.ch using the command: xrdcp --tpc only --force --path --posc -DIFirstConnectMaxCnt 2 -DITransactionTimeout 60 -DIRequestTimeout 60 -DIReadCacheSize 0 -DSNetworkStack IPv4 root://castoralice.cern.ch:1094//castor/cern.ch/alice/raw/global/2015/12/13/10/15000246991020.1400.root?authz=$STOK root://ccxrtli223.in2p3.fr:1095//08/06625/00115dd8-a185-11e5-9717-0a23a10abeef?authz=$TTOK I get the following error message in the xrootd log file: 160310 14:11:15 26491 XrootdXeq: yvcalas.31672:[log in to unmask] pub IPv4 login as yvcalas cchpssdcache:/hpss4/xrootd/alice/08/06625/00115dd8-a185-11e5-9717-0a23a10abeef : No such file or directory (error 2 on cchpssdcache) 160310 14:11:15 26491 oss_MSS_Xeq: Unable to execute statx; no such file or directory 160310 14:11:15 26491 ofs_stat: yvcalas.31672:[log in to unmask] Unable to locate /08/06625/00115dd8-a185-11e5-9717-0a23a10abeef; no such file or directory cchpssdcache:/hpss4/xrootd/alice/08/06625/00115dd8-a185-11e5-9717-0a23a10abeef : No such file or directory (error 2 on cchpssdcache) 160310 14:11:16 26491 oss_MSS_Xeq: Unable to execute exists; no such file or directory TPC job 8: yvcalas.31672:[log in to unmask] copying xroot://lxfsrd45a01.cern.ch:1095//castor/cern.ch/alice/raw/global/2015/12/13/10/15000246991020.1400.root to /xrootd/alice/08/06625/00115dd8-a185-11e5-9717-0a23a10abeef [0B/0B][100%][==================================================][0B/s] TPC job 8: Run: [ERROR] OS Error: File exists 160310 14:11:16 27557 ofs_Run: /usr/bin/xrdcp ended with status 50 160310 14:11:16 27557 ofs_TPC: yvcalas.31672:[log in to unmask] /08/06625/00115dd8-a185-11e5-9717-0a23a10abeef [ERROR] OS Error: File exists 160310 14:11:17 26484 XrootdXeq: yvcalas.31672:[log in to unmask] disc 0:00:02 However the file does not exist locally: [root@ccxrtli223 06625]$ ls -l /xrootd/alice/08/06625/00115dd8-a185-11e5-9717-0a23a10abeef ls: cannot access /xrootd/alice/08/06625/00115dd8-a185-11e5-9717-0a23a10abeef: No such file or directory [ccxrtli223:1095] / > locate -d -m 08/06625/00115dd8-a185-11e5-9717-0a23a10abeef [ERROR] Server responded with an error: [3011] Unable to locate /08/06625/00115dd8-a185-11e5-9717-0a23a10abeef; no such file or directory I therefore don't know why XRootD think that this file exists... Note that in the xrootd configuration file (in attachment), I put the following line: ofs.tpc autorm echo logok pgm /usr/bin/xrdcp Do you have any idea which could explain this problem?
