Hi Andy,
in trying to set up a prepare-enabled staging system in Padova we
found problems in using the xrootd.prep directive. Here, the server
refuses to accept any value for it saying that the directory does not
exist (even things like /tmp).
Roberto spotted this small bug in XrdXrootdConfig.cc, after the
correction the server now starts but the prepare request still does
nothing. I put here the small fix and our test xrootd.cf file, please
could you have a look at it to see if we forgot to set something to put
the prepare at work?
BTW the normal staging works fine!
Thank you
Fabrizio
