Thank you for this guide. This was very helpful for me as I was setting up my home media/file server. I am using Ubuntu and Raid 1 for my backup storage and rotating hard drives off site.

[...] These are the instructions for the samba and RAID 5 Ubuntu server configuration that I prefer to use. It’s an easy to manage set up that yields 80+ MB/s with burst speeds of 100MB/s using 5400 rpm Hitachi Drives. This is just a quick rundown of the procedure so that it is not forgotten.

@Ked: please see my reply on comment #26 on what I do to ensure grub is installed correctly on both drives.

Thanks for an invaluable tutorial. My datacenter replaced a failing disk tonight and I had resynch the array.
the sfdisk trick was hugely helpful as was the info on adding the partitions to multiple MD raid devices (as per your discussion with David Morris).

I wasn’t quit sure what he meant about the grub changes though … Does this mean that if my other disk fails the system will be unable to boot?

I had to add ‘–raid-devices=2′ to the create command:

mdadm –create –verbose /dev/md0 –level=1 –raid-devices=2 /dev/sda1 /dev/sdb2

hopefully this will help people who are getting:
mdadm: no raid-devices specified.
