Recently we had an idiot at our co-lo provider flip some power switches and we lost an install fo Red Hat Enterprise Server 3. I am sitting at the console and the server boots automatically into single-user mode. This is because it determines that /dev/null is mounted on a read-only filesystem.

Ok so simple enough right? just

rm -f /dev/null
mknod -m 0666 /dev/null c 1 3

right? Well the problem is that because the OS thinks that /dev/null is mounted on a read-only fs, it will not allow me to remove it. So I also tried to run fsck agains the partition. Again no luck because the OS thinks it is ro. Specifically erroring out on /dev/null.

So what are my options at this point? Boot off the CD into repair mode? LOL hadn't thought of that until just now as I was typing.

But if you have any additional suggestions I would appreciate hearing them.

Hi
You can remount the partition in read and write mode. Just run this command
mount /dev/hdax -o rw,remount
And reboot ur system, u should be able to read and write that partition
/dev/hdax is ur partition which u want to mount in read write mode
Just check whether it can help u.
bye
