I should think the title says it all, and I should think the answer is quite simple, but since I haven't been able to find it, here I am again.
The problem is quite simple, I need to figure out why, on occasion, one of two drives in my laptop is remount read only. I can live with it, but it does happen too often. It seems obvious that the issue arise due to the part of my fstab stating:
errors=remount-ro
The question is why it happens, which I can't seem to figure out. I know this is something I should know, but I don't.Part of the problem presumably is that the first thing I do when I experience the problem, is restarting the system and thus, for a time at least, fixing the problem.
Anyway, please do enlighten me if you've got nothing better to do.
Best regards.

From the man pages of mount(8)
errors={continue|remount-ro|panic}
Define the behavior when an error is encountered. (Either
ignore errors and just mark the filesystem erroneous and con‐
tinue, or remount the filesystem read-only, or panic and halt
the system.) The default is set in the filesystem superblock,
and can be changed using tune2fs(8).
You probably have an error occur when mounting the drive, which is then mounted as read only.
I do not have any tips on solving the errors except trying fsck.

Thanks for the reply, but no, every thing works fine for days and then suddenly, I get issues because suddenly something can't be written, I check how the drive is mounted, and I find that it's mounted read only, though that hasn't been the case from the start. I should probably also mention that it's not the root file system, but the /home which has a dedicated hdd. I should think that I could remount it once again once this problem occur, without the need to reboot, or fsck or what not, but as the issue does repeat itself often enough, I am concerned, and would thus like to figure out what the issue is. That is, what particular error get it to remount-ro.
Best regards.

Perhaps it's a hardware problem or a filesystem problem (you haven't mentioned which filesystem type you are using)?
Have you tried running a smartctl test?

GTP/etx4 and no. Haven't the slightest clue what smartctl is, but will look it up at once.

Perhaps you'd see errors in dmesg after it gets remounted read-only.

I had the same thought, but after I rebooted of course. I would have thought the information was still available, but I can find it.

An I/O error like this usually points to a hardware problem, which your logs show is on sdb1, so you try smartctl from the smartmontools package to test the entire sdb disk and not just partition 1
https://wiki.archlinux.org/index.php/S.M.A.R.T.
smartctl -t short /dev/sdb
and then
smartctl -a /dev/sdb

I already did a short test, which didn't seem to turn up anything, and am now in the process of doing a long one. However, I just looked at overall health. The -a flag tells me that there's no errors logged, nut I don't know if that's because I'm in the process of a new test or not.

When the long test has completed, post the output from

Okay, so it took a bit longer than intended, as for some odd reason the test kept getting interrupted, but in the end I got it to work and here's the output.

I suppose, but it does seem unlikely. I'll make sure to check though, if I can pull my self together to take appart my laptop.

How would you know your issue was similar? Is it simply similar symptoms, or have you read something from the test results I haven't?

I recognize line 2, and I suppose it kinda coincides with the remount incidents... Well it's hard to say, as I don't really know when exactly it happens.

I count 8 incidents this year, some of which I may not even have notices, so it is about the right amount actually. As for the rest, of the errors, they don't apply to me, at least they don't appear in the logs.
So, what does "WRITE FPDMA QUEUED" mean, and what does it mean for it to fail, what might be the cause, and might it be the cause for the remount-ro?
I am a philosopher, of sorts, not a troll or an imbecile.
My apologies that this is not always obvious, despite my best efforts.

many questions
I don't have anything particularly illuminating to add. Do your own googling. Reading the kernel source code is probably best - which is of course horrendous.
At this point, what you *should* be doing is assessing the potential risk vs reward of what I suggested, and just doing what I suggested - it's easy, and pretty safe.

And I'll probably try it out, if nothing else turns up, but in short I haven't the slightest clue what your suggestion does, or how to assess if it has helped, since I don't know the cause of the issue. Google is of little help, and to be blunt I do not have the skills to look through the source code of anything more complicated than a terminal based tic tac toe game.
Anyway, thanks again.

Have you tried swapping cables / SATA ports?
Searching the FPDMA message gave me: http://askubuntu.com/questions/141862/i … 880#141880
among other results indicating drive failure and faulty power, connector or cables.
And do you have any idea of when it remounts? (during file transfer, after idle time, etc.)

A bad connection is somewhat unlikely, but it's of course an option, which swapping sata port and probably cable isn't, since it's a laptop.
The only thing I can think of that may have an affect, is some heat issues I've had on occasion lately.
Anyway, I'm pretty tired now, but I'll make sure to check out the link and get back later or in the morning, when/if I've got anything to add.
Thanks.

It limits the speed to 1.5GB/sec, rather than 3GB/sec - which is hugely important if you're using (old-style) hardware (e.g. motherboard, RAID controller, or the drive itself) which doesn't *support* 3GB/sec.
If it works, the error messages will completely disappear.
Just try it. It's about speed, and low-risk.
