3ware Auto-Carve Question

[Justin Piszcz]

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.

Hm, did not appear to help.
