HOWTO: Remove RAID Arrays
The filesytem should not be mounted.
sudo umount /dev/md0
Stop the array allowing us to remove thew array.
sudo mdadm --stop /dev/md0
sudo mdadm --remove /dev/md0
Remove the marker from the disk that it was part of an array
sudo mdadm --zero-superblock /dev/sdb1
sudo mdadm --zero-superblock /dev/sdc1
sudo mdadm --zero-superblock /dev/sdc1
Now remove the array from the mdadm.cong file and rebuild the RAM image in initr. WE may need to find the UUID for the drives, blkid lists them all.
sudo blkid
sudo nano /etc/mdadm/mdadm.conf
sudo update-initramfs -c -k `uname -r`
