Setting Up LVM Partitions in Linux

Filesystems and their maintenance are one of the most common things any system administrator or engineer has to do when provisioning or maintaining systems. Creating a disk configuration that allows you the flexibility to grow or shrink a filesystem as needed will allow you to react to any requirement changes your systems undergo. After this hands-on lab, you will be able to create and work with LVM filesystems to adjust their sizes as needed.

  1. Challenge

    Create the Physical Volume Group of Disks and Verify

    1. Install the LVM package:

      yum install lvm2 -y
    2. List out the device names:

      fdisk -l
    3. Assemble the disks into a group that can be used by the Logical Volume Manager:

      pvcreate /dev/xvdf /dev/xvdg /dev/xvdj
  2. Challenge

    Create the Volume Group to Use

    Add the physical volumes to the volume group. Let's call this group myvol. Use the vgcreate utility, and then pass in the (3) physical volumes we created earlier:

    vgcreate myvol /dev/xvdf /dev/xvdg /dev/xvdj
  3. Challenge

    Create the Logical Volume of 60 GB

    Create the logical volume itself, using the lvcreate command and the appropriate flags:

    lvcreate -l 100%FREE -n devdisks myvol
  4. Challenge

    Format and Mount the LVM Filesystem

    Create the EXT4 filesystem:

    mkfs -t ext4 /dev/myvol/devdisks

    Create the directory to mount the filesystem you created:

    mkdir /mnt/newvol

    Mount the filesystem:

    mount -t ext4 /dev/myvol/devdisks /mnt/newvol

    And verify:

    df -h
