I think I got it. I used the "systemct1 disable storage" command to dismount the drive.
I then followed the instructions. However, the box hung during copying the files over. it got to copying picons. I was unable to give the "umount /tmp/data" command. I pulled the plug and rebooted the box. The box rebooted normally.
It seems to be working OK.
Is there a way to make sure everything went OK? It does seem snappier but it just may be a placebo effect.
