You do realise than there is a LUN limit in Linux of 2TB? But you can
this by implementing LVM2.
So a few RAID5 arrays, using LVM2 to create virtual luns, and your
jour on top should suffice. I would avoid having loads of disks in a single
array, it kills performance. better to seperate them into seperate
then LVM can join them together.

Yeah, why not.
