Logical Volume Management is used to treat seperate disks as one. However, this can cause trouble when trying to access the disks from a recovery CD, etc.

Mounting

To mount lvm partitions from a livecd (for purposes of recovery/emergency maintenance), simply:

  1. modprobe dm-mod to load required modules
  2. lvm vgchange -ay to become aware of the volume groups
  3. mount as normal with mount /dev/vg_(machine-name)/(distro-name) /location/to/mount/to.
