shell command to fix filesystem
I'm using Fedora 16 Verne but before it was Beta. My problem began when I just had updated my auto YUM software updates yesterday, 12/15/11 and it updated Linux kernel from fedora (3.1.5-1.fc16.i686) to (3.1.5-2.fc16.i686) rpm 32bit, then my laptop started acting unstable with a sign Oh no! Something has gone wrong. A problem has occurred and the system can't recover. Please log out and try again. So I did that and then it read Need to contact adminstrator, of which I am. After booting up, everytime it displays....even if I try booting the other 2 earlier Linux kernels, dracut still drops to command shell and gives this same read-out:
Booting 'Fedora (3.1.5-2.fc16.i686)'
Loading Fedora (3.1.5-2fc16.i686)'
Loading initial ramdisk...
_Fedora-16-Beta-: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. (i.e., without -a or -p options)
dracut Warning: e2fsck returned with 4
dracut Warning:_Fedora-16-Beta-contains a file system with errors, check forced.
dracut Warning:_Fedora-16-Beta-: Inodes that were part of a corrupted orphan linked list found.

dracut Warning: * Dropping you to a shell; the system will try
dracut Warning: * to mount the filesystem(s), when you leave the shell.
dracut Warning:
Dropping to debug shell.
sh: can't access tty; job control turned off
(Repair filesystem):/#
ANY HELP would be most appreciated because I haven't the slightest clue how to fix this nor what went wrong. I tryed typing in fsck and it then reads fsck from util-linux 2.20.1 (or how do I leave the shell?)
