How to mount LVM partitions from rescue mode

This is a short post about mounting LVM partitions when you are using a rescue CDROM or a desktop install CDROM. The whole process is only four easy steps.

  1. Boot your rescue media. This can be a CentOS, Ubuntu, Red Hat or other CDROM that gives you a console access to the server. Most newer linux distributions have LVM support available.Scan for volume groups
    # lvm vgscan -v
  2. Activate all Volume Groups
    # vgchange -a y “volume group name”
  3. List Logical Volumes
    # lvm lvs –all
  4. You have now activated the volumes and have all the information you need to mount them
    # mkdir /media/your-mount-point
    # mount /dev/volumegroup/logical-volume /media/your-mount-point

You can now look into /media/your-mount-point and see the content of your mounted LVM volume.
