I am helping a colleague update a six-year old SuperMicro system with an Adaptec 4000 SATA RAID controller with 1 TB drives. I have tried to configure the array from the array manager invoked at ctl-A during boot. If I try to include more than two drives in the array, it complains that 2 TB is the maximum size. The options for formatting are "Volume", "RAID0" and "RAID1". Does anyone know what "Volume" means? Does anyone know why the limit is 2 TB? (You can't have RAID5 with less than three drives.) I have tried to install Centos 6.2 on the drives and the installer crashes at the hard drive configure and mount stage with a "cannot find lv_home" error. I believe this is due to a lack of driver(s) beyond v5 according to help I've received on the Centos forum, but if anyone knows of a solution (beyond installing v5) I'd like to hear it.
