my file system went to read only mode, how to recover?

Asked by Neha Chaudhary on 2019-08-28

I am using ubuntu14.04 for five years. Recently, due to an improper shutdown, my system went to read-only mode. I am not able to do anything in that system, even internet is also not working. I tried to fsck but it didn't work for me. I also tried fsck in recovery mode and using a live USB. Nothing is working. I even tried to grub repair thinking that it may write my filesystem in rw mode but now my system won't even boot. I want my system in read-write mode. What should I do?

Support for Ubuntu 14.04 has already ended, except for paid extended maintenance for server systems. https://wiki.ubuntu.com/Releases

In my opinion the only reasonable action is booting into a live system, creating backup copies of all files that are worth being saved, and then do a clean new installation with a supported Ubuntu release.

Neha Chaudhary (jessica3188) said : #2

Thank you for your response.

I want to save data on that system but I can't. I tried live USB and tried
to backup the data but I can't copy that data because of ro mode.

Manfred Hampl (m-hampl) said : #3

I suggest that you use two USB sticks. One with the installer to boot in life mode (as you already did), an then adding a second one for storing the data.

Neha Chaudhary (jessica3188) said : #4

I cant open any folder in that drive. So, I am not able to transfer any
files from the system.

"I cant open any folder in that drive" - in which one?

Neha Chaudhary (jessica3188) said : #6

The drive in which Ubuntu is installed and went to read only mode. I have
dual boot.

If you boot from an USB stick in the "try Ubuntu without installing" mode and then issue the command

sudo fdisk -l

what output do you receive?

Neha Chaudhary (jessica3188) said : #8

Hi,

I am attaching the snapshot of the output.

Attaching files does not work in Launchpad questions.
The output of "fdisk -l" is plain text, so please copy/paste it as text.

I assume that your Ubuntu file system is /dev/sdd5 (~700 MB)
Is this correct?

What happens if you try mounting /dev/sdd5 to an empty directory?

Neha Chaudhary (jessica3188) said : #12

You are right, it is sdd5.

Can you please tell me how to mount /dev/sdd5 to an empty directory???

This seems to now show the contents of your Ubuntu 14.04 installation.
You should be able to create backup copies of all your files if you want.

I can't. I still can't access the folder content I wanted. Permission

You will need administrative rights.
Open a terminal window and issue the command

sudo nautilus

This will open a file explorer window with unlimited access rights. Use caution.

For the boot problem:

I suggest that you run the boot-info script https://help.ubuntu.com/community/Boot-Info and create a report on pastebin.

Neha Chaudhary (jessica3188) said : #22

Thank you for your help!
So, as my system is in read-only mode, it cant be corrected??? Is there any
way I can use and keep working on my system???

Manfred Hampl (m-hampl) said : #23

To be able to give hints how to repair the system, it is necessary to know why the system is in read-only mode.

Please provide the output of boot-info by booting a live system in the "try Ubuntu without installing" mode, installing boot-info, and running it with uploading the results to pastebin.
https://help.ubuntu.com/community/Boot-Info

Can you help with this problem?
