Getting system out of "read-only" file system.

AmYisraelChai · 08-07-2014, 09:27 AM

Hi all, I had an error while online so my laptop kicked me off chromium and switched to read only file system. I am currently in the grub system recover screen. I have typed in the following command(s):

Mount-o remount, rw/

Mount-o rw/dev/sda1/mnt/sda1

Mount/proc

When I just typed mount -o remount, rw
it seemed to actually acknowledge it by spitting back the following: EXT4-fs (sda2): re-mounted. Opts: (null)

But I honestly do not know what I am doing. Am I on the right path? Help!

Thank you- Rachel Yahalom

Yeah, that wasn't too far off

Code:

 mount  -o  rw,remount  /

remounts the / drive with the options rw, and remount.

It dropped you into a ro shell because of some disk error, in all likelihood. It sounds like it needs a disk check. You can do it in read only mode, not write mode, as that messes up the disk.

Also, in my experience, when a disk goes read-only, something is bad. If you have important things on the disk, copy it elsewhere while in read only mode. Running disk-checking can make matters worse if it's hardware errors and the disk is nearly dying.

Thank you very much. I was able to restore it.
