Mdadm and LVM2

In order to create a software raid array on linux you must install mdadm. This can be done during the install of the distro using either an alternative install disc, a live disc, or ubiquity.

To mount an existing linux raid array:

1. Make sure mdadm is installed by using your package manager

• In Ubuntu: $sudo apt-get install mdadm

2. Probe necessary modules

• $sudo modprobe raid5 dm-mod

3. Scan and mount any detected arrays

• $sudo mdadm --assemble --scan

If LVM is involved just make sure to install it first

• $sudo apt-get install lvm2
