OK, we will look into this.

Yes. 190 nodes have up to 150 GB of local disk space
the total of which makes quite a bit of space isn't it ... This
space is well served by rootd + our SUMS (scheduler) and hopefully
Xrootd will allow at first (without too much efforts) to make
static-population to a dynamic population (we have the "other"
advantages in mind too of course) ; the distributed-disk model
support would be a minimal objective ...
What is the reasonning behind the 64 limit ?? I have not
looked at the source code and wondering if this is a low level
limitation or a simple hard-coded choice ??
