2 possible ways:

/forcefsck way for /

# touch /forcefsck

and reboot. Next time the / will be fsck'ed .

systemd way

Add these 2 kernel boot parameters:

fsck.mode=force
fsck.repair=yes

What these 2 kernel parameters do:

KERNEL COMMAND LINE

systemd-fsck understands one kernel command line parameter:

fsck.mode=

    One of "auto", "force", "skip". Controls the mode of 
    operation. The default is "auto", and ensures that file 
    system checks are done when the file system checker deems 
    them necessary. "force" unconditionally results in full file 
    system checks. "skip" skips any file system checks. 

fsck.repair=

    One of "preen", "yes", "no". Controls the mode of operation. 
    The default is " preen", and will automatically repair 
    problems that can be safely fixed. "yes " will answer yes to 
    all questions by fsck and "no" will answer no to all 
    questions.
