{{note box| We go to work with [http://www.sysresccd.org/SystemRescueCd_Homepage SystemRescueCd] wich is a Linux system rescue disk available as a bootable CD-ROM or USB stick for administrating or repairing your system and data after a crash.[http://www.sysresccd.org/Download Download]. The goal is to get mounted your logical volumes on /mnt where you can save them on a usb disk.}}
start the system with your system rescue cd or you usb stick, choose your keyboard settings
then start the server X
startx
next start a terminal, after verify if your raid is initated.
cat /proc/mdstat
if you are lucky the output will look like this
# cat /proc/mdstat
Personalities : [raid1]
md99 : active raid1 sdb1[1] sda1[0]
104320 blocks [2/2] [UU]
md100 : active raid1 sdb2[1] sda2[0]
262036096 blocks [2/2] [UU]
unused devices: <none>
so we need to launch the LVM
vgchange -ay
afterward if the LVM is launched without error messages, we can mount the LVM in /mnt
mkdir /mnt/recover
mount /dev/main/root /mnt/recover
{{tip box|if you have a name of logical volume who is not '''/dev/main/root''', you can type this command for knowing all your logical volume, and adapt this to your configuration.}}
lvdisplay
Now you have successfully mounted your LVM and able to read your data on /mnt/recover, you can save them on a usb disk with the file browser for example.
==Method B==
Let’s try starting the raid and see what we get:
