I would just grow out aggr0 and save the space.  There are only a few corner cases
where having a dedicated root aggr makes any sense and they are rare.  So while it may
be nice to have, I wouldn't bother on a system of that size.  It would, indeed, be a horrible waster
of space.
 
With one shelf of disks, 99% of customers should set up a single RAID-DP aggregate with a single
spare.  There are exceptions, but without knowing anything else about your environment or future
growth plans, that's what I'd do.

Subject: 1 disk shelf with 1 head....using just aggr0

Would anyone recommend not using/growing aggr0 if I only have 1 disk shelf
Currently I have 1 vol0 in agr0 (1 data disk + 2 paratiy)
I would think that creating a second aggr would be just enormous wast of 300GB disks
What is the best practice? Should I just grow the aggr0?
Thanks
