Challenge
Install VDO and Ensure the Service Is Running
-
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.
-
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
