bpsched doesn't want to talk to the disk.  

15:15:20 [14115] <8> req_stunit_available: didn't find required storage unit
Disk1 in list of storage units

Is there a way to reread the storage units without bouncing all the daemons.
I have a duplication going right now I don't want interrupted.

-Mark

Prior to 4.5 storage units are prioritized alphabetically.  Each is
allocated as many jobs as possible before the next is used.

In 4.5, you may set up a storage unit group and prioritize the storage
units within the group to your liking.  You then use the group as you
would a regular storage unit (sort of, I don't think groups of groups
are legal).

I don't know, but it is a little more involved than that.  Look up
diskfull_notify in the NBU SAG.

You could use compression at the client side, keeping in mind that
it'll probably be slow and CPU intensive.
