Hello,
at CNAF Tier 1 site I see that SE info providers for Castor system
publish constant values for both Storage Space Available/Used.
This value is set to 100 Petabytes, since the unit of measure for these
attributes is kilobyte.
About this, I would like to raise two issues:
1. are there/will be there any fix for this problem in order to have
dynamic info?
2. this value causes problems to applications that represent integer on
4 bytes. If they use a signed int4 (worst case), the max value is
2G*Kbyte=2Terabytes. I'm promoting the change of the unit of measure to
megabyte for next GLUE Schema revision. This would allow to represent up
to 2G*Mbyte=2Petabytes for a single storage space in the worst case
(signed int4). For more info:

Below you find the queries that show the problem.
Cheers,
Sergio
