Install zfs on centos

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.

It is a vital step for ZFS file system installation. 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. 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:.

To do this you can use the rpm command followed by a link. 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:. By typing this, the installation of ZFS will be started. ZFS is robust, scaleable, and easy to administor. Thanks to zol zfs on Linux we can now enjoy its features on linux as well as BSD based distributions.

ZFS uses storage pools as a way to manage physical storage. I am installing this on a server running Centos 7. The difference between these is that if you install DKMS based ZFS module, and then for some reason you update the kernel of your operating system, the ZFS kernel module must be recompiled again. Once your computer starts, run the following command to check whether ZFS kernel module is loaded.

You may not see any output. In that case, run the following command to load the ZFS kernel module manually. Now if you run lsmod command again, you should see ZFS kernel module loaded as shown in the screenshot below.

RAID0 just pools your drives into what behaves like one giant drive. Initially they were 2. Snapshots are read-only copies of the ZFS file system at a specific point in time. They do not consume any additional storage space in the ZFS pool. We can either revert to the same state at a later time or extract just a single file or a series of files as per user requirements. In this article, you learned how to install ZFS on CentOS 7 and how to use some basic and important commands from the zpool and zfs utilities.

This is not an exhaustive list. ZFS has a lot more features and you can explore them further from its side official page.
