After you installed updates or a new program? Or when you a opened a program perhaps? Also what command were you trying after sudo that returned the error message? And what exactly do you mean your system became read-only? Could be please be a little more clearer? –Nitin Venkatesh Feb 20 '12 at 3:22 Of course. well, I updated right before this problem came up. Any sudo command, by the way, yields this error. Terminal says after enteri

It is a way to prevent possible data corruption. Your next would be to take a backup of all important data from this drive since this could also mean that the hard-drive could be on its way out. When you rebooted the machine, the / partition got mounted back in the regular rw mode from the read-only it had gone to before rebooting. You must run an fsck on the / partition to check for any inconsistancy. Since it is the root partition, I believe you will have to get into rescue mode to run the fsck. share|improve this answer answered Dec 15 '14 at 11:23 Sreeraj 2,27521328 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy
recently encounter it in one of my OS's installed in my laptop...there are many of them ..this is on Ubuntu... After booting( I am accessing this partition after month or two!) it works fine for few minutes then all of a sudden it went back to Read-Only mode and that too root fs...irk...real irk...:( So, I was doing an update to that OS after a while as I said..and it bug me twice..so started to hunt down that problem.I started to look around different aspect of fs and finally look at fstab..and it was little different then I thought. The root fs was has the parameter of "on-error=errors=remount-ro" and which is missing the "defaults" option. Okay, what's the big deal with that "defaults" option..very big deal indeed.Please check out the mount man page to find out more about that option. From the man pages of mount: defaults Use default options: rw, suid, dev, exec, auto, nouser, and async. Now , I hope you understand why :) But why the hell it was missing from the option in fstab file ...I was wondering..probably last update?or something else?Because I haven't had change anything in that file IIRC...or ...let me know if you believe and prof of something else doing that .. Mind you, I have done two round of fsck after being hit by that to bring down that os and do it from other os partition.And the fsck fixed up few more thing..but still it was happening...so adding that options is simple and worked for me. Hope this will help. Cheers!

Good to hear that...you might read this :Why does a file system go in read only mode?Problem: you have never intended to set your filesystems in read-only mode, but sometimes when your system is up, they remount of their own will. Why does this happen?Distributions often set an option in fstab that cause a filesystem to be remounted when an error occurs, which is typically caused by wrong on-disk format (maybe you have some bad blocks on your disk?). So check if the option errors=remount-ro is set on the filesystem:[root@lhost ~]# cat /proc/mounts(...)/
