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:

Also as the problem could be with my script, is there a log file where I
would see any output generated from it?
cheers
