<p>Create the <em>tank</em> zpool containing a raidz vdev spread
over 3 devices.  It is recommended that you use the persistent
/dev/disk/by-id/* device names when creating your pool to avoid
any device reordering issues latter.  Your device names will of
course be different.</p>

$ sudo zpool create tank raidz scsi-SATA_Maxtor_7Y250M0_Y638RXME

<p>Your <em>tank</em> pool will automatically contain a filesystem
which is mounted under your root directory.  You can create additional
filesystems with the <em>zfs create</em> command.  They will also be
automatically mounted.</p>

<pre>
$ sudo zfs create tank/fish
$ df -h -t zfs
Filesystem            Size  Used Avail Use% Mounted on
tank                  459G  128K  459G   1% /tank
tank/fish             459G  128K  459G   1% /tank/fish
</pre>

<p>Some other useful <em>zfs</em> subcommands are <em>mount</em>,
<em>unmount</em>, <em>destroy</em>, and <em>snapshot</em>.  These
are all fully described in the zfs man page and should be enough
to get you started.</em>
