 In this blogpost its important to clarify a common point of confusion: ZFS as implemented in Oracle Solaris is not directly available on Oracle Linux . Oracle’s version of ZFS— ZFS on Solaris (Solaris ZFS) —is tightly integrated with the Solaris kernel and is proprietary. Oracle Linux, on the other hand, is based on the Red Hat ecosystem and uses the Unbreakable Enterprise Kernel (UEK) , which does not include Oracle’s Solaris ZFS . However, you can deploy a version of ZFS on Oracle Linux 9 using the OpenZFS project, which is the open-source continuation of ZFS development. Enable Required Repositories: Oracle Linux does not include OpenZFS by default. Use the EPEL repository or build from source, but the cleanest method is usually via kmods or DKMS packages . sudo dnf install -y epel-release Install OpenZFS You can build from source or install from the OpenZFS packages . A third-party repository such as ZFS-on-Linux or a compiled RPM may be available. dnf install -y https://...

In the last blog post we have seen how we can install the ZFS rpm packages on Oracle Linux 8 Operating System and now in this blog post, we will see how to configure and create the zpool on Oracle Linux 8 operating system.  Check the ZFS services: [root@localhost ~]# systemctl -a | grep zfs zfs-import-cache.service loaded inactive dead Import ZFS pools by cache file zfs-mount.service loaded inactive dead Mount ZFS filesystems zfs-share.service loaded inactive dead ZFS file system shares ...
