Creation of ZPOOL on Oracle Linux 8

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

preset the ZFS services:

[root@localhost ~]# systemctl preset zfs-zed
[root@localhost ~]# systemctl preset zfs-import-scan
[root@localhost ~]# systemctl preset zfs.target
[root@localhost ~]#  systemctl enable zfs-import-scan.service
Created symlink /etc/systemd/system/zfs-import.target.wants/zfs-import-scan.service → /usr/lib/systemd/system/zfs-import-scan.service.
[root@localhost ~]#
