This is a function that should be available since corporate data is

data can be huge. Take into consideration the XRAID, how much time
would
it take to restore a complete 1Tb or larger array. What if it's
already
partitioned and you need to make the one of the first partitions
bigger?
does this mean you need to delete all partitions and then recreate and
restore everything. Only if it goes south during the re-size.
Then you do it after hours or on a weekend after a good backup.
Restore time
is a function of backup methodology so the time answer is"It depends"
Note that growing partitions only reallocates space. If that RAID's
full,
changing partition sizes, if even possible, won't do you a bit of good.
As well, on a RAID setup, the only purpose for partitions is if you
need
exclusive access to data by machines in a way that permissions can't
handle.
Jacob mentioned corporate data. That could also require 24/7 uptime.
It's not something Apple has delved much into yet but is one of the
biggest advantages of a lot of the commercial UNIX disk solutions out
there. HFS means they'll have to do it special. And I agree with him,
the XRAID/XSAN solutions are eventually going to require this.
