Install ZFS File On Centos 8 Step By Step
Let’s start reviewing the steps of this guide to learn and finish it.
Step 1: First, you are recommended to check the repositories already installed on Oracle Linux 8, use the command below to show you which are already been installed.
Then, install Yum utilities to prevent facing probable problems during the installation.
yum install yum-utils
In this step, you must install the EPEL repository in Oracle Linux 8. It is a vital step for ZFS file system installation. You are recommending to install the EPEL RPM file directly from the official Fedora Project website.
dnf install https://dl.fedoraproject.org/pub/epel/epel-release -latest-8.noarch.rpm
Note: If you are asked to press “Y” or “y” to continue the installation, hit “y” from the keyboard to let the EPEL repository be download and install. Wait for a while to install the EPEL repositories on Oracle CentOs 8.
Again, confirm the installation by the same command as below:
Once you confirmed your installation, you should enable the EPEL utility in your system. Run the following command in the terminal followed by epel name.
yum config-manager –enable epel
You may feel some of the EPEL modules are not being install, so you can install an extra package of Enterprise Linux Modular 8 by running the command below:
yum install –y dkms
The latest step to install the ZFS file system on your system is to download it from the official ZFS website. To do this you can use the rpm command followed by a link.
rpm –Uvh <a href="http://download.zfsonlinux.org/epel/zfs -release.el8_2.noarch.rpm">http://download.zfsonlinux.org/epel /zfs-release.el8_2.noarch.rpm</a>
In this way, the ZFs rpm file would be successfully download in your Oracle Linux 8.
Just now, you will be able to install the ZFS file system by running the yum command followed by the keyword zfs as below:

Once you loaded the driver, you can check for the loading packages status of the ZFS file system using the following command:
systemctl –a | grep zfs
Running the above command helps you to observe the active, inactive, and failed utilities and services.
Also, to see what utilities are enabled and disabled, type the command below:
systemctl list-unit-files | grep zfs
Use the following command to mutually connect the utility services at the same time.
systemctl preset zfs-import-cache zfs-mount zfs-share zfs-zed zfs-import-scan zfs-target
By this, you can enable the services. Type the command below to enable a single disabled utility service.
systemctl enable zfs-import-scan.service
If you verify for the utility services, you see that previously disabled services are now enabled.
systemctl list-unit-files | grep zfs
Now, you can check for the devices already running in correspondence with the ZFS file system. Use the following command with the _l keyword to list devices.
After running, you can see a list of Devices and disks currently present in your system with their information regarding size, ID, type, start, and endpoints.

4- Aso, to check the current status of a pool:
5- Run the following command to import the pool:
zpool import pool_name
6- And to export the pool:
zpool export pool_name
7- Use the command below to delete a pool anytime
zpool destroy pool_name
8- To create a ZFS file system using pools, run:
