Thanks for this. What we were roughly planning to do is to create a
pool for one VO that wants about 30TB of disk (the lion's share of what
we recently acquired) and another pool with the rest of the disks that
we will enable for every VO except the storage-hungry one.
I was just asking as, from a management perspective, it would have been
more convenient to have a single pool and just cap what individual VOs
can use from it.
Cheers,
Geoff.
