reboot forcing a fsck

I have a server which seems to have a fs issue for my exim folder.
an "ls -l" hangs. anything going near the exim folder hangs - for 
whatever reason.

If I trigger a 'reboot', I assume the boot process will automatically 
enter a fsck as per the documentation.

What is unclear is if the system will eventually g et to multi-user 
mode, or hang at a CLI question from the fsck?

I have no hands or eyes available to be there. This is a bare metal 
chassis not a vm.

Would appreciate learning the procedure which fsck uses during a boot.
(beyond what the man fsck advises) which seems to exclude this question.

Thanks
