rhel visudo Read-only file system

Hi guys, I am trying to add a new user as a sudoer using visudo and system is complaining about file system read only.

Code:

visudo
visudo: /usr/local/packages/sudo_remote/1.6.7p5/etc/sudoers: Read-only file system

this is not making drive read write:

Code:

mount -o remount,rw /

How to make sudoers file read-write so visudo works?

Thanks.

OK, dumb question: Are you running visudo as root?

OK you believe this FS is mounted ro you can check that with:

Code:

grep "\sro[\s,]" /proc/mounts

If that doesn't work for you then simple

Code:

cat /proc/mounts

and look to see how the FS was mounted.

If it's ro then remount with

Code:

mount -o rw,remount /

If this doesn't make the FS read/write then you might have ab FS issue and should run a check against it once you have unmounted it.
