Hi Wilko,
Are you using dcache xrdxp command ? Do you use dcache for storing the
data ?
At Uvic, we are installing dcache with tape (TSM) to store BaBaR data.
We can copy the data to tape and access it through xrootd door.
I am wondering how to keep bookkepping about it ?
Any advise ? Do you know anybody storing BaBar data on dcache and
accessing throuch xroot door and keeping bookkeeping of it ?
Thanks,
Ashok
