I've installed Ubuntu 14.04, and I'm getting read only file system(/dev/sda3) randomly. Previously I was using Arch linux(3.14 lts), which had the same problem but discarded due to other problems. I tested the partition with badblocks(read only test) but got no error. Here is the dmesg output after I got the error

  • Your dmesg output shows lots of errors, check your drive's S.M.A.R.T. status and report back

Looks to me like you have a hardware problem. If this is a sata drive, you could replace the sata cable, or at least check the connectors etc... Otherwise, could you update the question with fdisk -l output.

  • Reinserted the hard disk cable. Still getting same behaviour.

  • Can you replace the sata cable? The number is I/O error's would suggest hardware not configuration. Can you also show the output of sudo fdisk -l Mar 10, 2015 at 16:51
  • Just added the output. See the EDIT. Replacing of cable is not possible any time soon.

Actually there were no badblocks in sda3 but I found many in sda2. All my stuffs were in sda2. So this read only behaviour was arising only when I was using sda2 like listening to music, working on a project etc. Reading these badblocks in sda2 was causing remounting of sda2 as read only filesystem.

Can I tell fsck not to read these badblocks on sda2(it is NTFS formatted because I'm dual booting )?

I have had this problem on my computer for over 1 year and tried everything to solve the problem. Suddenly Linux goes into read-only mode. If you are editing something you are unable to save and have to execute fsck command and reset the computer. The computer is also very slow and freezing all the time. I removed the dual boot and left only Ubuntu, upgraded Ubuntu from version 18.04 LTS to version 20.04 LTS, and it didn't work. What was crucial to solving the problem is the use of the dmesg command. The experience didn't work out for me, just this command. The function of this command is to monitor the computer.

In my case, the problem was related to the SSD incompatibility with Ubuntu. I used HDD and after I switched to SSD the problem came up. The problem was solved by updating the SSD firmware, which was only possible by partitioned Windowns, because Kingston does not have the program to update firmware through Linux. I also installed the dual boot Windowns and Linux, first installing Windows over the entire SSD, then deallocating space through Windowns and installing Ubuntu, but it is very unlikely that this was the solution to the problem.
