View Full Version : [ubuntu] Jaunty on 150Gb raptor but /home on two 1Tb drives in RAID1

Hi helper folks,

I'd like to create a new system from scratch. The hardware I'd like to use would be to run linux from a 150Gb SATA drive (WD Raptor) and store my home partition on another separate 1Tb SATA drive which will be mirrored on a third 1Tb SATA drive. The reason for doing this is that most of the programs and such I want to load quickly, while all my documents and such I want backed up.

My motherboard claims to support Raid 0,1,5,JBOD, but I read over here on FakeRAID (https://help.ubuntu.com/community/FakeRaidHowto) that this is not true raid: it is a multi-channel disk controller that runs through the BIOS with certain drivers to help the OS boot from a raid device.

Since linux has built in softRAID support, I was going to skip configuring the motherboard RAID support, but I wanted to know if I could get some help setting up the RAID in linux and how I should proceed through the setup wizard when installing linux, e.g. an order of operations such as (example, not sure if its right)

1) during install denote the / partition will be on the 150gb drive
2) denote the /home partition will be on the 1Tb drive
3) install
4) configure softRAID to mirror the 1Tb drive on the second 1Tb drive.


2) during install denote that the 2nd and 3rd drives will be mirrored in RAID1??
4) no step 4, already completed during the OS install

Any help would be appreciated.
