Alguns e-mails trocados para tentar colocar o crab server em atividade para o CMS, em hn-cms-t2@cern.ch, de Alessandra Fanfani:

about 1-2TB. Few hundreds of GB are not enough to safely handle users 
sandboxes.
Is the storage area you are planning to use as CRAB server storage
a GridFTp server?

Did you already performed tests of the server with a local configuration 
file as suggested in:
https://twiki.cern.ch/twiki/bin/view/CMS/CrabServerInstallation#Testing_the_CrabServer
?
If yes, then you could ask to the crab development HN: 
  hn-cms-crabDevelopment@cern.ch
</pre>
De Mattia Cinquilli:

Here the problem is that the server can handle that protocol (and  
storage), but the WMS is not able to work with a dcache system (with  
different pools). So, actually, the solution is to have gridFtp  
installed on the same machine of the server with a dedicated disk/ 
partition, or (better performance) to have a dedicated machine with  
just gridFtp (as Legnaro setup).

Coloca o que fez.
