Hi I'm having problems interfacing MPS with the MSS at RAL and was wondering if anyone has any ideas that could help me. I have a script to retrieve data from our MSS at RAL (MSSGet.pl). This works well with mps_stage on the command line. I'm now trying to set this up within the xrootd.cf config file. I have added the following lines to the config file on a server machine mps.stage.xfrcmd /opt/xrootd/utils/mps_Stage mps.stage.msscmd /home/csf/olaiya/testspace/area1/MSSGet.pl However when I ask for a file that is in the MSS but not on disk it does not get staged. Is there any other directives that people believe I should add to the config file? When I restart xrootd and oldb on the dataserver I see all the ofs and oss directives printed out in the xrdlog file. I don't see any of my mps directives printed here which makes me think they aren't interfaced. Am I supposed to see the directives here or is there a separate log file where I can monitor mps output? This is the tail end of my xrdlog: ofs.authorize ofs.redirect target ofs.fdscan 9 120 1200 ofs.maxdelay 60 ofs.trace 0 040909 23:31:02 21726 oss_Init: (c) 2003, Stanford University, oss Version1.0.0 040909 23:31:02 21726 oss_config: Storage system initialization started. 040909 23:31:02 21726 oss_config: Storage system initialization completed. /opt/xrootd/etc/xrootd.cf oss configuration: oss.alloc 0 0 0 oss.cachescan 600 oss.compdetect * oss.fdlimit 512 1024 oss.maxdbsize 0 oss.localroot /stage/bdata-data38/kanga oss.stagecmd /opt/xrootd/utils/mps_Stage oss.mssgwpath /tmp/gateway.mss.21726 oss.trace 0 oss.xfr 1 9437184 30 10800 oss.path /store r/o oss.cache public /stage/bdata-data38/cache/ oss.cache public /stage/bdata-data46/cache/ 040909 23:31:02 21726 oss_MSS_Init: Mass storage interface initialization started. 040909 23:31:02 21726 oss_MSS_Init: Mass storage interface initialized. 040909 23:31:02 21726 Prep log directory not specified; prepare tracking disabled. 040909 23:31:02 21726 Exporting /store 040909 23:31:02 21726 XRootd protocol version 2.2.0 build 20040901-0613 successfully loaded. 040909 23:31:02 21726 [log in to unmask]:1094 initialization completed. Also as the problem could be with my script, is there a log file where I would see any output generated from it? cheers Manny
