Quick question-- under Kernel 2.4 without 2TB support enabled, the only other 
option is to use auto-carving to get the maximum amount of space easily, 
however, after doing this (2TB, 2TB, 1.8TB) for a 10 x 750GB array, only the 
first partition remains afer reboot.

Before reboot:

/dev/sdb1 (2TB)
/dev/sdc1 (2TB)
/dev/sdd1 (2TB)

After reboot

/dev/sdb1 (2TB)
sdc1 <vanished>
sdd1 <vanished>

I also tried formatting and then labeling /dev/sdc1 and /dev/sdd1 with 
mkfs.ext3 and then e2label, same thing, sdc/sdd disappear after reboot. Is 
there some option somewhere to ensure that sdc/sdd 'carved partitions' are 
not forgotten about?

Thanks,

Justin.

Ah this appears to be my issue:
