Installing TNSR Using Software RAID¶

This document describes the process of configuring the TNSR installer to use multiple disks via Linux software RAID. Ubuntu implements Linux Software RAID devices through the md (Multiple Devices) device driver.

Follow the Installation Process until the Configure Storage step
Select Custom Storage Layout

Custom Storage Layout¶
Select the first disk and Use As Boot Device

Use As Boot Device¶
Select the first disk and Add GPT Partition

Add GPT Partition¶
Create a new unformatted partition
- Leave Size blank to use the full disk
- Set Format to Leave Unformatted
- Select Create
Create Unformatted Partition¶
Repeat the previous three steps for the second disk (use as boot device, add GPT partition, create a new unformatted partition)

At this point the disks will each have a new partition and either an EFI partition or a BIOS grub spacer:

Basic Partition Layout¶
Select Create software raid (md)
- Set RAID Level to 1 (mirrored)
- Select partition 2 on each disk
- Select Create
RAID (MD) Disk Configuration¶

The result will look like RAID Device, Ready for Use:

RAID Device, Ready for Use¶
Create a swap partition
- Select md0 and Add GPT Partition
  
  Add GPT Partition on md0¶
- Set Size to the desired size for a swap partition (e.g. 2G, 4G, etc, based on RAM size and available disk space)
- Set Format to Swap
- Click Create
Create Swap Partition¶
Create root partition
- Select md0 and Add GPT Partition
- Leave Size blank to use all remaining disk space
- Set Format to an appropriate filesystem type (e.g. ext4)
- Set Mount to /
- Select Create
