RAID and Partition Size limit?

[Kall, Bruce A.]

I'm trying to set up a (hardware) raid.  It has a logical drive 
dimensioned at 3.5 TB (it's a Promise Tech RAID box connected to my 
system with an Adaptec SCSI Card and contains 15 250GB Hard drives 
running raid5).  I would like to have one large ext3 disk partition on 
this.  Every time I run fdisk on it, it tells me the partition size is 
1.286TB.

Is there a limit on partition size in the Linux kernel or is this a 
fdisk problem or perhaps something else?
