About this Hands-on Lab

Requirements change, and datacenters evolve. Being able to manage storage configurations on the fly is an important skill. Ansible allows for that using the `lvg`, `lvol`, `filesystem`, and `mount` modules. This lab will allow you to practice using those modules.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Set up the New Disk with LVM, and Use the Logical Volume Name “AppDB2”

This section of your playbook should look like:

   - name: Create the Volume Group
     lvg:
      vg: RHCE
      pvs: /dev/xvdg

   - name: Create Logical Volume
     lvol:
      lv: AppDB2
      vg: RHCE
      size: 10G
      pvs: /dev/xvdg
      state: present
Format the Disk Using XFS

This playbook section should look similar to:

   - name: Format the disk
     filesystem:
      dev: /dev/RHCE/AppDB2
      fstype: xfs
Mount the Disk

This section of the playbook that looks like this:

   - name: Mount the disk
     mount:
      fstype: xfs
      src: /dev/RHCE/AppDB2
      state: mounted
      path: /mnt/appdb2

Additional Resources

Notice: Ansible is installed as the root user, so please work on all tasks after elevating to the root user.

Management has purchased a new application, which of course needs database access. Our Database team has requested that a new disk be allocated and configured, to make room for this additional requirement.

Write a playbook that configures /dev/xvdg to have 10G of disk space in a logical volume named AppDB2. Make sure it's formatted using XFS, and mounted at /mnt/appdb2.
