Thanks all. It turns out I *do* have the so-called 'fake-RAID' as was suggested earlier. I've made some progress....but....

I get the following results: ASUS:/home/rich # dmraid -r /dev/sda: nvidia, "nvidia_baedieei", raid5_ls, ok, 781422766 sectors, data@ 0 /dev/sdb: nvidia, "nvidia_baedieei", raid5_ls, ok, 781422766 sectors, data@ 0 /dev/sdc: nvidia, "nvidia_baedieei", raid5_ls, ok, 781422766 sectors, data@ 0 /dev/sdd: nvidia, "nvidia_baedieei", raid5_ls, ok, 781422766 sectors, data@ 0 ASUS:/home/rich # dmraid -ay -i ERROR: device-mapper target type "raid45" not in kernel I am using 10.2 with the latest kernel available via normal updates that I am aware of without going to alpha versions. Even though this system is a dual-core AMD, I chose to install a 32bit OS initially to get things set up before tackling the somewhat sparse 64 bit world that I see has even more challanges ahead :( OS: Linux 2.6.18.8-0.3-bigsmp i686 System: openSUSE 10.2 (i586) KDE: 3.5.5 "release 45.4" My question now appears to be, what do I have to do to get the 'raid45' target type error resolved? I don't want to use a 'lower' raid level than raid 5 because with 1Tb of space, I want very badly to have the redundancy offered by that mode without an unnecessary redundancy of hardware backup required by 'lower' raid levels. As the fake-raid supports level 5, I'd like to use it if possible. My next goal would be to be able to install and boot using the raid5/dmraid techniques suggested in the above URL, but for now, I'd be content with solving the 'raid45' error. Thanks in advance.
