    Why the down-votes? This looks like a decent question & I didn't find any exact dupes. +1 from me. – Tom Brossman Jun 29 '12 at 19:35
  • @TomBrossman The word “implement” in the title evoked a programming question, at least to me. I changed the title. – Melebius Nov 22 '18 at 13:35

RAID 1 is mirroring; where data is duplicated on two different drives using either a hardware RAID controller or software (via the operating system). If either drive fails, the other continues to function as a single drive until the failed drive is replaced.

First thing that needs to be done is to install mdadm. To do so

Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command below.

apt-get install mdadm

Or use USC

Once that is done,

Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command below.

mdadm

--create creates a new RAID device

and follow the instructions

If you want to install on a boot volume with RAID, you can't use the desktop install CD. You need to use the "alternate install" CD:

http://www.ubuntu.com/download/desktop/alternative-downloads

Inside that installer you'll have the options to create a RAID (MD) device and/or use LVM.
