Mint Install Notes

Background Information
I wanted to run a desktop with two drives in RAID 1 (Mirroring) mode for data protection. Red Hat and CentOS support the hardware RAID controller, but Ubuntu, Mint and Debian Workstations do not, and do not natively support the software RAID. The instructions below are how I overcame the Workstation limitation.
Hardware Configuration
Ensure that you start with 2 drives of equal size, and that they are not configured for hardware RAID.
Boot from Mint install disc in "Live" mode
There are many steps before you get to run the installation program, so make sure that you are running in the "Live" or "try is out" mode.
Start terminal window
Become root

For new Mint Installations
Zero Drives
Zero the first drive to ensure that the drive is empty.
mint ~ # dd if=/dev/zero of=/dev/sda bs=1048576 dd: writing ‘/dev/sda’: No space left on device 953870+0 records in 953869+0 records out 1000204886016 bytes (1.0 TB) copied, 6393.41 s, 156 MB/s
Also zero the second drive to ensure that it is empty.

Partition Drives
*** NOTE: You will want to increase the /boot partition from 128M to 256M. 128M will be too small to have more than one kernel installed, and this will cause you grief.
Option 1 fdisk
mint ~ # fdisk /dev/sda
The device presents a logical sector size that is smaller than
the physical sector size. Aligning to a physical sector (or optimal
I/O) size boundary is recommended, or performance may be impacted.

Option 2 cfdisk
Partition the first drive
mint ~ # cfdisk /dev/sda
This prings up the menu-driven partitioning program. You will set up 2 partitions, set the type to FD, set the first partition to be bootable, and then write the partition table. The partitions should look similar to that below.

Set up the partition table for the second drive.

This bring us the same menu-based application, and you do the same to this drive.

Create RAID volumes
We will delay creating the first RAID array that will be used to house the /boot partition as the Mint installer has issues.
IGNORE THE NEXT COMMAND
mint ~ # mdadm --create /dev/md0 --metadata=0.90 --level=raid1 --raid-devices=2 /dev/sda1 /dev/sdb1 mdadm: array /dev/md0 started.
Create the second drive array. This will house our LVM.
mint ~ # mdadm --create /dev/md1 --level=raid1 --raid-devices=2 /dev/sda2 /dev/sdb2
mdadm: Note: this array has metadata at the start and
may not be suitable as a boot device. If you plan to
store '/boot' on this device please ensure that
your boot-loader understands md/v1.x metadata, or use
--metadata=0.90
Continue creating array? yes

Run installer
When asked for partition information, choose "do something else" option, and set up the partition tables there. Use /dev/vg1/lv1 for the "/" volume, /dev/sda1 as the "/boot" volume, and /dev/vg1/lv2 as the "swap" volume. Do not use /dev/sdb1 for anything.
Continue the setup, filling out the optional dialogues.
When installation finishes, click "continue testing".
