Comment 47 for bug 220493

Ok I've done everything I can find for "8.04 64bit Server" to make my nvidia RAID5 work.
if I do # dmraid -s
*** Set
name : nvidia_fegfedde
size : 2930319456
stride : 32
type : raid5_ls
status : ok
subsets: 0
devs : 4
spares : 0

Happy days! So then I...

# dmraid -ay
ERROR: device-mapper target type "raid45" not in kernel

If I do....
~# locate raid4
/lib/modules/2.6.24-16-server/kernel/drivers/md/raid456.ko
/lib/modules/2.6.24-16-server/ubuntu/md/dm-raid4-5.ko

What ! is raid456? How do I get a RAID 5 to work under Ubuntu? The Array is empty, I want to format it to ext3
How do i make this work?
