Force an fsck on reboot. Useful on a system where / has mounted read-only because of file system issues.

touch /forcefsck

Can't use "touch /forcefsck". Root file system is mounted read-only due to disk problems. Cannot write to /. Cannot "mount -o remount,rw /" either.

What now? :)

at grub boot screen, hit 'a', append 'init=/bin/sh', after booting into shell you should be able to do the fsck, or do the remount and touch /forcefsck

also try single user mode (just append '1')
