Comments on Recover Data From RAID1 LVM Partitions With Knoppix Linux LiveCD
Recover Data From RAID1 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 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.

Hi guys I have been looking all over for something like this and it seems to be what i am looking for. I have a RAID array and i need to get the data off the disk and rebuild the machine yet I cannot mount the drive - or when i mount it all i see is the Lost+Found directory that is read only I was following the steps laid out above but when I try to run the mdadm step it does not create the conf file for me - a default one is already there - am i doing something wrong. I have knoppix 6 live cd and i have the Red Hat Enterprise 5 version Any help is greatly appreciated Thanks Kev
