2 TB, this will have to change soon. (Yes, that also means it can't
support RAID arrays with more usable space than 2 TB).

No, LVM-style RAID won't be limited. Traditional hardware RAID or "fake"
hardware RAID (as found in many PC motherboards), on the other hand,
will see the 2TB limit on usable space. This is because the disks are
presented to the operating system as One Big Device, and both the BIOS
and operating systems will expect there to be traditional partitions on
that device.

Ok, thanks for the clarification. I'm no RAID expert, and I thought
I had missed something important, because I couldn't see why it
would be a limitation.

You have found the bank of Larn.

I speak only for myself, and I am unanimous in that!
