Ilinux-raid want to create raid0 use mdadm 2.5.6, kernel 2.6.18-iop3 on the intel iop80331(32bit). use 5 disks, and every hard disk is 500G. But it can't beyond > 2T.  How can support >2T on the 32bit cpu ?  

command and log :
#mdadm -C /dev/md0 -l0 -n5 /dev/sd[c,d,e,f,g]
# mdadm --detail /dev/md0

  

I have many arrays which are 12TB or greater - so I don't think this is
your problem.
It looks like mdadm is only using 60GB from each disk.

What output do you get from these commands:

fdisk -l /dev/sdc

mdadm --examine /dev/sdc

?
