How to fsck / while system running

Is there any way to run fsck while the system is running. I'm trying to mount the system ro (ex. mount -o remount,ro /) but it keeps telling me the system is busy. Any ideas? Thanks for your time..

what runlevel are you in? did you offload the filesystem ( unmount /proc, /sys, etc.. whatever is in your /etc/fstab that gets mounted at boot ( do "cat /etc/mtab" to see what is currently mounted))?

I was in runlevel 5. I know if I go to runlevel 1, I can remount ro and run fsck, but I was wondering if it can be done on runlevel 3 or 5.
