First we need to add the ZFS on Linux repository to our system by installing a zfs-release package as shown below:
$ sudo yum localinstall --nogpgcheck http://archive.zfsonlinux.org/epel/zfs-release-1-3.el6.noarch.rpm $ sudo yum install zfs
Once, zfs has been installed, we can create a storage pool. There’re many RAID configuration to choose from, and I’m not going to get into it. However, if you want to learn more, you can read this ZFS Administration article which explains in great detail about ZFS RAID(Z).
In my case, I have three 1TB disks and pick RAIDZ-1.
