I wonder if that would affect me as i am planning on doing 1 raid

LVM drives into the current group. So i would have >2tb but it would
be spread across 2 raid devices and 8 disks.

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.
You reall need to read up on parted, it has some very nice features
(though I find it a little clumsy at the commandline). I copied an 80 Gm
HDD to a file and set to, manipulating the partitions in parted. It
failed when I tried to move an extended partition, but it's come a long
way since last I looked. Andrew is to be commended.
I think there are a couple of GUI wrappers for it too.
