Checking a mounted root drive

When I boot up linux it always tells me that "mounting an unchecked filesystem". Then it ask if I want to run fsck but when I do it warns me "checking a mounted drive may cause SEVERE filesystem damage." How do I check the mounted drive since it wont let me unmount the drive so I don't get that message.

You cant. You will have to boot from a bootfloppy containing the tools needed. In som cases, typing "linux single" at the liloprompt might bring the system up in a usable state. But the best bet is a boot floppy.

Or you coult try typing "linux init=/bin/sh" at lilo to get a shell and run from there. But to answer your original question

"You cant safely check / fix a mounted filesystem"
