The array I'm building is 7.5TB across 15 500GB SATA2 drives. In
communication with the vendor over this, I found out that little tidbit
about fdisk. So, I'm going to have to do the same thing with LVM
groups. I understand there might be a performance hit on this, but I
won't know until I get it built and tested. Does anyone know the deal
with FDISK? Are there plans to fix that little problem? I mean pretty
soon 2TB is gonna be a drop in the bucket for most filesystems, and
considering ext3 handles 64TB or more, this seems a horrible limitation.
