You don't say how much RAM you have, and I am not familiar with how much RAM is needed to fsck a big ufs2 file system.

I would look into SU+J.

My biggest hard drive is 3 TB, and biggest partition only a small percentage of that, and OpenBSD can't read any part of it.

I don't think OpenBSD would be suitable.  OpenBSD lacks support for GPT, also no support for USB 3.0.

Only way I use OpenBSD is live USB from liveusb-openbsd.sourceforge.net .  I managed to get X to start by tweaking an xorg.conf from NetBSD, but still the mouse pointer remained invisible.  Only way I know the mouse pointer existed was by what part of the screen became active.  So that USB stick sits inactive most of the time.
