I have a Raid with about 5TB and no problems creating an xfs filesystem on it. 
The system is Novell SLES10 with a 2.6.16.21 kernel. 

At first there was a problem with the raid. The firmware of the raid device 
needed an upgrade. Bevore the upgrade I had a maximum of 2TB. 

In dmesg (or /var/log/boot.msg on SLES10) you should see something like this 
message if the device (sdc here) is handled correctly:

<5>sdc : very big device. try to use READ CAPACITY(16).
<5>SCSI device sdc: 10156243968 512-byte hdwr sectors (5199997 MB)
<5>sdc: Write Protect is off
<7>sdc: Mode Sense: cb 00 00 08
<5>SCSI device sdc: drive cache: write back
<5>sdc : very big device. try to use READ CAPACITY(16).
<5>SCSI device sdc: 10156243968 512-byte hdwr sectors (5199997 MB)

Bevore the firmware update there was an error when trying to read the capacity 
via READ CAPACITY(16).  

I created the partitiions using parted. fdisk did not work.

Have a nice day
Rainer
