How to safely remove mdadm raid 1

Hi,

My situation: I have the Ubuntu OS ruing in raid 1 on two identical disks and I am wanting to break the raid array, and just have the OS on one normal disk.

Has anyone got any experience with this?

I have searched around and seen a few forum posts, most notably this one:

http://ubuntuforums.org/showthread.php?t=1693950

which looks good, but still does not seem to offer a concrete solution to this. I need to know whether this is something that can actually be done and is relatively safe to do.

My thoughts at the moment are to:

boot from a livecd and then apt-get install mdadm. 

sudo mdadm --zero-superblock /dev/sda1
sudo mdadm --zero-superblock /dev/sdb1
etc...

remove /etc/mdadm/mdadm.conf from the remaining drive, and update /etc/fstab to mount the remaining drive by UUID, and finally update grub to reflect booting from the individual disk partition rather than the RAID array.

Thanks
