Challenge

Install VDO and Ensure the Service Is Running
1. To install VDO, run:
```
yum -y install vdo 
```
  We need to install with this method because of the kernel version that the lab server is using.
2. Once complete, start up the daemon and enable it to run after reboot:
```
systemctl start vdo && systemctl enable vdo
```

Challenge

Set up a 100G VM Storage Volume

To set up the VDO storage volume, run:

vdo create --name=ContainerStorage --device=/dev/nvme1n1 --vdoLogicalSize=100G --sparseIndex=disabled

Set up a filesystem:

mkfs.xfs -K /dev/mapper/ContainerStorage && udevadm settle

Create a mount point, and then mount the filesystem:

mkdir /mnt/containers && mount /dev/mapper/ContainerStorage /mnt/containers

Add the filesystem to /etc/fstab to mount it after reboot:

/dev/mapper/ContainerStorage /mnt/containers xfs defaults,_netdev,x-systemd.device-timeout=0,x-systemd.requires=vdo.service 0 0

Challenge

Set up a 60G Website Storage Volume

To set up the VDO storage volume, run:

vdo create --name=WebsiteStorage --device=/dev/nvme2n1 --vdoLogicalSize=60G

Disable deduplication:

vdo disableDeduplication --name=WebsiteStorage

Set up a filesystem:

mkfs.xfs -K /dev/mapper/WebsiteStorage && udevadm settle

Create a mount point, and then mount the filesystem:

mkdir /mnt/website && mount /dev/mapper/WebsiteStorage /mnt/website

Add the filesystem to /etc/fstab to mount it after reboot:

/dev/mapper/WebsiteStorage /mnt/website xfs defaults,_netdev,x-systemd.device-timeout=0,x-systemd.requires=vdo.service 0 0
