Mounting error at boot


I am new at using pfSense v.2.3, and I keep getting a error 22 code when trying to run pfSense during the setup screen. I have not tried any troubleshooting yet cause I don't want to make a mistake I can't turn back from. Please help.

Shouldn't this question go to pfSense? I know it is a derivative, but pfSense is their baby...

Or if you can send a screenshot/dump, that would help.
