I'm studying up on mounting and unmounting stuff, and other related topics such as fsck.
I want to do a fsck on the root file system, just to do (incase the worst comes, I know the process), but as all of you probably already know, you cant (or shouldnt) do a fsck on a mounted filesystem. I have booted into linux single user mode, both from the lilo prompt and using a boot disk, but I when I check what is mounted with the mount command it says my root file system is already mounted. I cannot unmount it using the umount command. So I was just wondering how I am to go about unmounting /
BTW I am running Red Hat 8 and am a major linux
Thx for the help;
