Thanks for the response. I'd already been through https://help.ubuntu.com/community/FakeRaidHowto before posting here. While somewhat helpful, it's geared toward setting up to boot off the RAID, which is not my goal. That said, I gleaned what I could, but was was stopped cold at the get-go:
"Run the partitioner program gparted (System->Administration->GParted)
9.10 loads dmraid automatically so you should see for a disk device
/dev/mapper/pdc_feddabdf or some suchlike
if dmraid detected and can use a fakeraid partition"
There is no /dev/mapper/ device. The devices comprising the RAID show up as discrete, independent disks.
I've updated to the latest dmraid just in case that was an issue, but still no joy ... :'(
If it's just not possible I'd like to know so that I don't sink more time into a lost cause. It's a bit hard to accept that functionality that worked with previous incarnations of the chipset would be unsupported for the latest chipset, which has been on the market and in wide use for 2.5 years.
If anyone has anything to add, I'm all ears.
Thanks!
David
