I'm not an advanced nix user and I think an addition is required on this page in the handbook:
The section "Adding disks" covers setting up the slices, however it does not mention having to use newfs (or newfs_hammer in my case) to finally have the disk ready for use.
I'd suggest just adding a one liner to the effect of - to finalise/format your disk you must use newfs and offer an example or link to the documentation.
I wasn’t aware I could edit it - I didn’t think a numpty like me would be allowed ;)
Done now, kept it short and sweet.
