I've got a system with a 3ware 9000 RAID card with 12 250GB SATA drives.
And another one with two 3ware 9000 RAID cards each with 8 250GB SATA drives.
Both are running kernel 2.6.8-1 (521) 686smp (Systems are dual Xeon 2Ghz HT).
I've got no problem with the 2nd system. Both arrays are 1.75 TB and running fine. However I'd like to join both disks on a single volume.
The 1st system I cannot get the system to recognize the full 2.5 TB.
This is my syslog:

However df (and everything else) reports:

/dev/sdb1 513G 528K 513G 1% /root/home
What is going wrong?
How can I manage to join both 1.75TB on a single volume? (volume manager doesn't support above 2TB does it?)
Thanks in advance.
