-There are many different ways to organise the storage of your FreeNAS server. I can’t tell you what is best for you because it depends on various factors, how many vdevs and Zpools you want, how many data storage drives you have available, etc.  Review [[https://forums.freenas.org/index.php?members/cyberjock.22572/|cyberjock]]'s [[https://forums.freenas.org/index.php?threads/slideshow-explaining-vdev-zpool-zil-and-l2arc-for-noobs.7775/|guide to ZFS for newbies]] if you aren't thoroughly familiar with it.+There are many different ways to organise the storage of your FreeNAS server.

 Whatever way you decide to arrange things make sure you build in some sort of redundancy. This goes for the vdevs as well. Whatever way you decide to arrange things make sure you build in some sort of redundancy. This goes for the vdevs as well.

 This is how I arranged mine. This is how I arranged mine.
  
-Go to the “Storage” page.+Click "Storage" in the left column, then "Pools".
  
-{{:fester:a498b5b6cf563286a07cf54dd573f267.png}}+{{:fester112:pasted:20190526-232837.png}}
  
-Now click on the “Volumes” button (1) if it is not already selected.+Now click on the “Add” button.
  
-Then click on the “Volume Manager” button (2). This will open up another smaller window.+{{:fester112:pasted:20190526-232937.png}}
  
-You have two options at this point.+At the this screen, the default selection is "Create a new pool"; leave this selected and click "Create Pool".
  
-You can stay in this window and supply some details to the FreeNAS OS and it will suggest a redundancy option which you can accept or change.+{{:fester112:pasted:20190526-233327.png}}
  
-The other option is to use manual setup (Fester always uses manual setup, it’s just my preference).+Give your volume a name in the “Name” text box. If you cannot think of anything then “tank” seems to be popular amongst FreeNAS users (I don’t know why?).
  
-Now click on the “Manual setup” button (3).+If you want the pool to use encryption then tick the “Encryption” box. But only do this if your processor supports AES-NI encryption and you have enabled it in the BIOS, otherwise don’t use it. Remember to save a recovery key.  **Again, unless you have a specific legal or regulatory requirement for full-disk encryption, this is discouraged.**
  
-{{:fester:a75f221f88fff40300297d7a3be7bed9.png}}+If you like, you can click "Suggest Layout", and FreeNAS will select a layout that's generally sensible.  Otherwise, you can manually select the disks you want in your pool as shown here:
  
-Give your volume a name in the “Volume name” text box (1). If you cannot think of anything then “Tank” seems to be popular amongst FreeNAS users (I don’t know why?).+{{:fester112:pasted:20190526-233518.png}}
  
-If you want the Zpool to use encryption then tick the “Encryption” box (2). But only do this if your processor supports AES-NI encryption and you have enabled it in the BIOS, otherwise don’t use it. Remember to save a recovery key.+Then click the right arrow button to move them to the "Data VDevs" list:
  
-Now select the storage drives you want to form part of the Zpool in the “Member disks” selection box (3). To select all available disks click on the first drive, hold down the “Shift” key and with the key held down click on the last disk.+{{:fester112:pasted:20190526-233601.png}}
  
-Leave “Deduplication” set to **off** (4) (unless you understand deduplication and have plenty of RAM in your system).+At the bottom of that list, you can select any form of vdev (strip, mirror, RAIDZ//n//) that's appropriate to the number of disks selected.
  
-If you did not select all the available storage drives in the “Member disks” section then you will have the option of choosing the function of the unused disks in the “ZFS Extra” section. This is where you can designate a disk/s as a spare device that will immediately be utilised when one of your disks fail, or as an extra cache or log for ZFS and the FreeNAS OS. I always use all the available drives so this section has disappeared by this point.+Then click the "Create" button to create the pool.
  
-If you selected all available drives in the “Member disk” section then you will see a section entitled “Group Type”. In the “Group Type” section, select with the appropriate radio button the type of redundancy you wish to utilise in the Zpool (5) (Fester likes Raid-Z2 as this allows two devices to fail and the zpool is still operable. If a third device fails the zpool is trashed).+{{:fester112:pasted:20190526-233808.png}}
  
-Now click the “Add Volume” button (6).+You'll see a pop-up window warning you that all data on the disks you're adding to the pool will be erased.  Check the "Confirm" box, then click the "Create Pool" button.
  
-{{:fester:c6e0c56122e3f62cd4b7d46c9ab22403.png}}+{{:fester112:pasted:20190526-234050.png}}
  
-When the operation completes often the FreeNAS GUI may not update to reflect the change, so you don’t see your newly created volume listed under “Volumes”.+When the operation completes you'll be returned to the Pools page.
  
-If this happens to you just navigate away from the page and then navigate back to it and the page will be forced to update. You should now see the volume listed. +{{:fester112:pasted:20190526-234300.png}}
- +
-If all goes well you should get something like this. +

-{{:fester:ea7c23bad23d4341dd603da54cb65181.png}}+
  
 That’s the FreeNAS storage volume created. That’s the FreeNAS storage volume created.
