Lately, I am trying to build a server that uses Ubuntu Server 12.04.3(64bit) . I am facing problem while wanting to install under a software RAID(RAID 1). My Server spec are as below:

Proccesor: Intel i5-4670 Motherboard: Asus H87M-E V1 RAM: 2X 4GB 1600mhz Hardisk: 2x 2TB WD Red Cavier

I already tried either Software RAID and Hardware RAID. Software RAID can't install bootloader and Hardware RAID won't let me partition. This is my first time directly doing RAID 1 on the OS HDD. Kind of Newbie here. Anyone who had this experience please share. Thank You

You can use Live-CD open ubuntu terminal and follow following steps.

sudo su

Then install mdadm

apt-get install mdadm

Using mdadm command to create raid1

mdadm --create --verbose /dev/md0 --level=mirror --raid-devices=2 /dev/sdb1 /dev/sdc1

Don't forget change /dev/sdb1 and /dev/sdc1 to match with your drive. And using the same command match all your partitions.

Then save raid configuration by using.

mdadm --detail --scan >> /etc/mdadm/mdadm.conf

That's it.

PS. Sometime I have to download installation from USA source because it won't allow me config raid
