=== Warning ===

 * You must create the RAID components from partitions, rather than entire devices.
   * E.g. use '/dev/sda1' not '/dev/sda'.
 * When you use the device names, the procedure works, but the RAID filesystem disappears after a reboot
 * See: [[http://askubuntu.com/questions/741994/raid5-disappears-after-reboot]]

=== Procedure ===

 1. See which devices should be used

V2 and MAPS Setup in Production

V2Master - V2Deployment

This Page Is Incomplete

Introduction

This pages describe how to setup MAPS and V2 systems in a production environment such that MAPS is used for authentication management for V2 systems.

Two use cases are considered:

  1. Installation of prototype systems
  2. Installation of a true customer facing production system

Installation of zg-2.softxs.ch

Hardware

  1. 2 x Intel Xeon E5504, 2.0 GHz, e.g. 2 x quad-core
  2. 32 GB Main Memory

  3. 500 GB SSD, Samsung SSD 840

  4. 2 x 4 TB disk drives, WDC WD4001FAEX-0

  5. Ensure VT-x is enabled in the BIOS

Disk Partitions

Memory Stick Preparation

  1. Download Ubuntu Server 16.04.2 LTS

  2. Use lsblk command to find USB device

  3. Command to download and copy of memory stick: 
    cd /home/backup
wget http://releases.ubuntu.com/16.04/ubuntu-16.04.2-server-amd64.iso
dd bs=4M if=ubuntu-16.04.2-server-amd64.iso of=/dev/sdd
