Hi Jean-Yves Using the trace all directive has helped. In at least I can now see the problem. I now see in the log file: 040914 14:06:30 8052 XrootdXeq: User logged in as olaiya.20722:14@csfe 040914 14:06:30 8052 olaiya.20722:14@csfe oss_Open_ufs: fd=512 flags=0 mode=0 path=/stage/bdata-data38/kanga/store/PRskims/R14/14.4.3d/BCCC03a3body/15/Manny_test.01.root 040914 14:06:31 8052 XrdLink: olaiya.20722:14@csfe disconnected after 0:00:01 040914 14:06:42 8041 XrootdXeq: User logged in as olaiya.20727:14@csfe 040914 14:06:42 8041 olaiya.20727:14@csfe oss_Open_ufs: fd=-2 flags=0 mode=0 path=/stage/bdata-data38/kanga/store/PRskims/R14/14.4.3d/BCCC03a3body/15/Manny_test2.01.root 040914 14:06:42 8041 oss_MSS_Xeq: sending to mss '/home/csf/bbdatsrv/bin/MSSGet.pl statx /store/PRskims/R14/14.4.3d/BCCC03a3body/15/Manny_test2.01.root' 040914 14:06:42 8049 oss_MSS_Gateway: received '/home/csf/bbdatsrv/bin/MSSGet.pl statx /store/PRskims/R14/14.4.3d/BCCC03a3body/15/Manny_test2.01.root' 040914 14:06:42 8041 oss_MSS_Xeq: received 'ub1017 * /store/PRskims/R14/14.4.3d/BCCC03a3body/15/Manny_test2.01.root' 040914 14:06:42 8041 oss_XrdOssMSS_Xeq: Unable to execute statx /store/PRskims/R14/14.4.3d/BCCC03a3body/15/Manny_test2.01.root; invalid response from mass storage system interface 040914 14:06:42 8041 ofs_open: olaiya.20727:14@csfe Unable to open /store/PRskims/R14/14.4.3d/BCCC03a3body/15/Manny_test2.01.root; invalid response from mass storage system interface 14/09 14:06:42 tape: Unable to open file /store/PRskims/R14/14.4.3d/BCCC03a3body/15/Manny_test2.01.root for writing 040914 14:06:42 8041 XrdLink: olaiya.20727:14@csfe disconnected after 0:00:00 Failed to read file to tape ub1017 at /home/csf/bbdatsrv/bin/MSSGet.pl line 21 Though I'm not too sure what statx is and where it comes from? cheers Manny Jean-Yves Nief wrote: > Emmanuel Olaiya wrote: > >> Hi Jean-Yves >> >> Thanks, I didn't have this directive but I have added it now.
