fsck on a live filesystem (hint: NO WRITE) is a bad idea. Doing an fsck that 
is supposed to repair stuff, always requires downtime, unless you use 
background_fsck. However, many people discourage it's usage as it can leave 
some errors unfixed.

In short: reboot in single user mode, then run fsck -y at the prompt.

Never ever run fsck -y on a live filesystem.

Problem with today's modular software: they start with the modules
    and never get to the software part.
