Recover Data From RAID 1 LVM Partitions With Knoppix Linux LiveCD
This tutorial describes how to rescue data from a single hard disk that was part of a LVM2 RAID1 setup like it is created by e.g the Fedora Core installer. Why is it so problematic to recover the data? Every single harddisk that formerly was a part of a LVM RAID 1 setup contains all data that was stored in the RAID, but the hard disk can not 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 to be able to mount it. I will use the Knoppix Linux LiveCD to do the data recovery.
Prerequisites
I used a Knoppix 5.1 LiveCD for this tutorial. Download the CD ISO image from here and burn it on CD, then connect the hard disk which contains the RAID partition(s) to the IDE / ATA controller of your mainboard, put the Knoppix CD in your CD drive and boot from the CD.
The hard disk I used is an IDE drive that is attached to the first IDE controller (hda). In my case, the hard disk contained only one partition.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
