It doesn't seem like the native ZFS support is fully baked unless I'm missing something.  I created a ZFS pool for my four disks, but the Shares tab demands that the Array be started in order to configure any shares, and the Array won't start because it has no disks.  So the native ZFS support is only if you have a non-ZFS array also?

 

 

Did you try setting the "Array" slots to 0 ?

The lowest number is 3

My bad, I just saw your version - the array is optional starting from Unraid 7.0 beta2: https://unraid.net/blog/unraid-7-beta-2

Unraid Array Now Optional

 

You can now set the number of unRAID array slots to 'none'. This will allow the array to Start without any devices assigned to the unRAID array itself.

If you are running an all-SSD/NMVe server, we recommend assigning all devices to one or more ZFS/BTRFS pools, since Trim/Discard is not supported with unRAID array devices.

 

To remove the unRAID array from an existing server, first unassign all Array slots on the Main page, and then set the Slots to 'none'.

For new installs, the default number of slots to reserve for the unRAID array is now 'none'.
