how to setup a software raid mdadm
 

I am running ubuntu 9.04 Can someone please help me setup and mount a software raid?


Here is what I have done so far
following this thread

http://bfish.xaedalus.net/?p=188=3
sudo echo "DEVICE partitions" > /etc/mdadm/mdadm.conf
bash: /etc/mdadm.conf: Permission denied

now I am dead in the water????

The permissions are probably not set correctly on the file if it already exists. You could use

sudo ls -l /etc/mdadm/mdadm.conf

to check.
