raid

This guide explains how to set up software RAID1 on an already running Debian Etch system. The GRUB bootloader will be configured in such a way that the system will still be able to boot if one of the hard drives fails (no matter which one).

This tutorial describes how to rescue data from a single hard disk that was part of a LVM2 RAID1 setup. Why is it so problematic to recover the data? Every single hard disk that formerly was a part of a LVM RAID1 setup contains all data that was stored in the RAID, but the hard disk cannot simply be mounted. First, a RAID setup must be configured for the partition(s) and then LVM must be set up to use this (these) RAID partition(s) before you will be able to mount it. I will use the Knoppix Linux LiveCD to do the data recovery.

This tutorial shows how you can set up a network-attached storage server with FreeNAS. FreeNAS is based on the FreeBSD operating system and supports CIFS (samba), FTP, NFS, RSYNC, SSH, local user authentication, and software RAID (0, 1, 5). It comes with a powerful web interface and uses very little space on the hard drive - about 32MB.

This guide describes how to install Ubuntu (Ubuntu+GNOME) or Kubuntu (Ubuntu+KDE) 6.06.1 LTS (Dapper Drake) on a single or a multi-boot RAID system. It is meant as a variation of Ubuntu Wiki FakeRAID HowTo document, but digested and with minimum commentary. Its goal is to allow new Ubuntu users to complete an entire installation within 30 minutes, almost entirely by copy and paste.

This guide shows how to remove a failed hard drive from a Linux RAID1 array (software RAID), and how to add a new hard disk to the RAID1 array without losing data.

This guide shows how to work with LVM (Logical Volume Management) on Linux. It also describes how to use LVM together with RAID1 in an extra chapter. As LVM is a rather abstract topic, this article comes with a Debian Etch VMware image that you can download and start, and on that Debian Etch system you can run all the commands I execute here and compare your results with mine. Through this practical approach you should get used to LVM very fast.
