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: Sep 28 14:13:02 heracles kernel: 3ware 9000 Storage

manager doesn’t support above 2TB does it?) Thanks in advance. Omar Castañeda Acosta Sysadmin iDEA |
