dmraid output:

ERROR: dos: reading /dev/mapper/nvidia_aecdafjf[No such file or directory]

Contents of /dev/mapper:
ubuntu at ubuntu:/dev/mapper$ ls
control  nvidia_aecdafjf

dmraid verbose output:

Kernel version:
ubuntu at ubuntu:/dev/mapper$ uname -r
2.6.28-11-generic

I started the Ubuntu 9.04 Live CD.   Used the package manager to
download dmraid after reloading the package list.   Installed dmraid and
updated libdevmapper1.02.1

The nvidia raid drive is raid 5 with (i think) 3 partitions, one ntfs,
one ext3 and one small (boot) partition.

The is the same raid drive I ran 8.10 on using dmraid.

Hope it helps.
