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
