Hi Tommaso,
I trust that your source modifications are working for you. Just to let
you know that git head now contains a stat() plugin mechanism and a sample
plugin specific to gpfs+tape. It's configurable and should do all the
things you wanted it to do. The plugin shared library is
libXrdOssSIgpfsT.so with the corresponding source in
XrdOss/XrdOssSIgpfsT.cc
We will now discuss when it will appear in a mainline release. This brings
me to another question regarding gpfs+tape staging. Presumably, when you
stage in a file using your interface, the file will appear on disk using
exactly the same name it originally had. Currently, this is not the
assumption of frm_xfrd since not too many people run such a tightly
configured staging system. So, I will also include an additional option to
the copycmd directive indicating that direct staging is the prefered
method so that the frm doesn't go through an intermediate file. I suspect
you have already hit that little detail.
Andy
