Can't boot up linux anymore :(

Hey all
I got a litle problem when trying to boot up my redhat 7.3

I got the following error message saying:

mounting proc filesystem: dup2 bad file descriptor

So basicly i can't do anything

I have no idea why it happend as far as i know i din't fuck around with anything

I only turned on the onboard soundcard in the BIOS
But i already turned it off but i still get the same error message

Any help would be very much appriciated as this is a school project

sort of sounds like the harddrive is full.

you need to boot into it with a rescue disk and check it out.

Well, actually someone fscked around with the thing for this to happen. Boot using the RH cdroms or floppy to get a shell, then run fsck on the disk without any flags (ie no auto or yes on everything). If the disk is full you may have to delete stuff first.

Actually, I got the same error, and I found the answer at UCLA - LUG. Turns out some software I loaded modifed /dev/null to be a regular file with some sort of message in it ... hence "Bad file descriptor".

I ran the following commands in maintenance mode, rebooted, and everything came back fine.

> mount -n -t proc /proc /proc
> mount -a
> mount -n -o remount,rw /
> rm -f /dev/null
> mknod -m 666 /dev/null c 1 3

hope that helps
