5.8TB RAID5 SATA Array Questions

[Edgar Martinez]

I don't think I have ever done that...or even considered that was
possible...The controller does support growing the array...Guess I'll give
it a shot starting with 2TB and then grow it in increments to see how it
behaves...any suggestions for newfs'in the device directly??

If your array is just going to used for one large filesystem, you can
skip any partitioning steps and newfs the base device directly.  then
if you decide to grow the array (and if your controller supports
nondestructive resizing), you can use growfs to expand the filesystem
without the extra step of manually adjusting a partition table.
