    Normally after booting after a power outage fsck will run automatically 
as part of the system startup, and will prune the filesystems 
automatically. If it finds an error it can't fix without help, it will 
drop you into a command line and tell you that there were errors that 
require your input to fix.

    At that point you can just run fsck {reported filesysem with errors} 
ie:

fsck /dev/ad0s1e

    Sometimes you may want to use the -y switch, but use it with caution.

man fsck  for more info on other options.
