freenas boot zfs error

[Rhino5]

I'm really lost as to how to handle this one.

Code:

Checking status of zfs pools:
NAME           SIZE  ALLOC   FREE  EXPANDSZ   FRAG    CAP  DEDUP  HEALTH  ALTROOT

status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.

        entire pool from backup.

I'm running the FreeNas 9.3 Beta from a USB stick. The USB does not show up in the GUI of course so there is no way to scrub it that I know of. I could just fresh install and restore the settings but 9.3 is so touchy to keep the plugins running that I would really rather fix it. Anyone able to give a scrub some unix lessons on command line scrubbing?
