Thank you very much for your replies; I have been away from my system for a while, but I have used both the commands recommended, and 1.) the disk is there, as it showed when I first installed Opnsense, and 2.) you guys were right about it saying 0% usage. It is simply not using 2.5 GB of the disk yet. Less than 1/2 of 1% shows as 0%.
Thanks again for the help!
