Mounting an Encrypted Disk

    sudo apt-get install cryptsetup            # Installs the tools we need to deal with encrypted partitions
    sudo modprobe dm-crypt                     # Inserts a module we need
    sudo cryptsetup luksOpen /dev/sda2 cheer   # Unlocks the partition sda2 and names it cheer
    Enter LUKS passphrase: 
    key slot 0 unlocked.
    Command successful.
    #
    # Now that we have unlocked the encryption, it's just dealing with the lvm
    #
    #
    sudo apt-get install lvm2  # installs the tools we need
    sudo modprobe dm-mod       # inserts a module we need
    sudo vgscan                # Scans for all volume groups
      Reading all physical volumes.  This may take a while...
      Found volume group "Ubuntu" using metadata type lvm2
    sudo vgchange -a y Ubuntu  # this made the VG Ubuntu active, if you don't give it a volume group as an argument it'll make them all active        
    sudo lvscan                # This command lists the logical volumes and their /dev path
      ACTIVE            '/dev/Ubuntu/Root' [15.00 GB] inherit
      ACTIVE            '/dev/Ubuntu/swap' [1.00 GB] inherit
      ACTIVE            '/dev/Ubuntu/home' [215.89 GB] inherit

    # Now I mount them to do whatever it is I need to do, if you wanted to run a fsck on them you obviously wouldn't mount them.

    ls /dev/dm*   # find the mapped devices
    mount /dev/dm-1 /mnt/disk1  # mount one
