  1. Challenge

    Create the Underlying Device

    To set up VDO we first need to install the software.

    yum install /home/cloud_user/kmod-kvdo-6.1.3.23-5.el7.x86_64.rpm -y

    Once that's done, we need to create a Logical Volume containing the two physical disks, since vdo can't span disks.

    pvcreate /dev/nvme1n1 /dev/nvme2n1

    vgcreate vdoDev /dev/nvme1n1 /dev/nvme2n1

    lvcreate -n vdoLV -l 100%FREE vdoDev

    Now that's done we have a 40G device we can work with.

    vdo create --name=RHCE --device=/dev/vdoDev/vdoLV --vdoLogicalSize=150G --sparseIndex=enabled

    to create the VDO device.

  2. Challenge

    Create a File System on the Device

    Super Simple:

    mkfs.xfs /dev/mapper/RHCE

  3. Challenge

    Mount the Device

    First we make sure the mount point exists:

    mkdir /mnt/video

    Then we can run

    mount /dev/mapper/RHCE /mnt/video

    And we're done!
